Trimble Positions Thread - Post Here

Thanks,

I received some answer through my support channels....the features that are giving me issues are in Geometric Networks. I guess Positions doesn't handle these types of datasets. My work around for now is to just use my generic features in the field and cut/paste them as the networked features after they are corrected.

I have to look into geometric networks more, so I can decide if I want to leave it as-is, and continue with the work around...or, remove the geometric network so I can use the features in my projects for data collection.

Miles...

In cases like this, I'd strongly recommend taking a look at the log file in C:\Users\<user>\AppData\Roaming\Trimble\Positions\10.1. It should give you more information about the nature of any problems on check-in. You may want to consult your Trimble support channel for deeper interpretation of any log messages. Although you can try posting specific messages here, I make no guarantees on getting a timely response.

Matt

OK, I got one for the group....

Just got back in from the field. Check-in the data to ArcMap, but it gives me the error "Failed to store 10 features. Do you wish to ...(then I forget)". I click OK, and it loaded all the Point features, but none of the lines (10 lines). However, when I click on the View Features button, all the line features do show up and I can see the vertices and accuracy outlines for each.

Not sure why they aren't fully transferred or checked-in. I'll see what happens after I correct the data.

Any thoughts?

Thanks.

Hi Joel...

This would typically happen when you installed a service pack, or performed an in-place upgrade of ArcMap, as the ArcMap configuration file would get replaced. Re-installing Positions Desktop would certainly re-trigger the installer code that changes the ArcMap configuration file, but you can also make the change manually by opening up the ArcMap.exe.config file (typically in \Program Files (x86)\ArcGIS\Desktop10.2\bin) and making sure that the <startup> section contains these 2 lines:

</startup>

Hi Joel,

Not sure why that would happen just from moving the license manager, but the release notes for Positions do address this error, and this fix might work for you? I’ve also found that just reinstalling Positions sometimes does the trick, and that might be easier.

During the installation process, the Trimble Positions Desktop add-in installer attempts to modify the ArcMap.exe.config file in the C:\Program Files (x86)\ArcGIS\Desktop 10.1\bin folder. Depending on permissions, this can sometimes silently fail… manually edit the ArcMap.exe.config file (using a suitable text editor, for example, Microsoft® Notepad) to make the

<!~~<supportedRuntime version="v4.0.30319"/>~~>

I am using Trimble Positions with ArcGIS 10.2.2. It has been working fine.

When I tried to do some recent post corrections, I got an error message:

“The ArcMap.exe.config file is missing the necessary modifications. Post processing cannot continue. Please re-install Trimble Positions or consult the documentation for making the changes manually.”

Would anyone know why this came up? We have recently moved our ArcGIS license manager to a new server. That is the only change I can think of that might be related.

I made a separate "MiscGeneric" geodatabase, that has a point, line and polygon feature class, all with a bunch of fields that are similar to the data in my main geodatabase. I put them in every one of my projects and DDFs, so that when I do come across unexpected things in the field, I can at least get them marked and have some range of fields available to fill in about them.

I wish I could remove the default ones in TerraSync, but as long as you name the Generic ones different enough for you to know which one is which, then there isn't much confusion.

MichaelMarcus

Matt,

I did use a few generic features while mapping. I came across a few unexpected items that needed to be collected for clarity that were not apart of my DDF. I will add a few "misc" features in my data dictionary to cover such situations.

Thanks for your help.

Michael...

In all likelihood, that error is a result of using generic features in the SSF. Unfortunately, this TerraSync option isn't currently supported in the Positions workflow.

As a reminder, this thread is probably not the most efficient way of getting support for Trimble Positions. It's only monitored by Trimble on an ad-hoc basis. Your Trimble Reseller continues to be the front-line for support along with information provided on the Trimble website and on http://positionsblog.trimble.com/.

I'm not sure if this is the correct place to ask this questions but here goes...

I'm trying to check in an ssf file into ArcMap 10.2 using Trimble Position Desktop Add-in 10.3.0.2. I was able to check in two of the three projects that were transferred from the Trimble Geo 7 unit using TerraSync software. The third ssf file returns an error message.

Can someone explain what this means and how I might resolve this.

Thanks

DeanAnderson

Vicky,

If you haven't solved the Passive Mode issue, check your antivirus software, that is what was causing that error for us.

Hi Vicky...

First step of troubleshooting would be to try copying and pasting the URL into a browser and seeing if you can download the files that way. If that works, you can always create a post processing profile that uses the local files as a workaround.

I am running Arc 10.2 with Arcpad 10.0 so had to upgrade from the Trimble GPS Correct and Analyst to the Trimble Positions.

I am no longer able to post-process my data using an established base station data (set up by adding records from a user list acquired by our software provider). The base station information is downloaded from an ftp site but I am no longer able to download the data.

The Details are that: "The remote sever returned an error: 227 Entering Passive Mode" and the differential correction fails because "No base data file found".

I have been working with our software provider's tech support who seems to think it is something to do with our server blocking the ftp but we did not have problems prior to updating to Trimble Positions.

I thought I would post on here to see if other users encountered this problem,

Thank you,

No worries. I'll take a look to see if something changed in a recent release. I believe it used to work although truthfully I haven't looked at that functionality in a long while.

Hey J. - Thanks for getting back to me so quickly. I did what you suggested and created a mobile cache from the same enterprise database dataset that was used to publish the mobile services but I left out the TrimbleSessions layer. When loaded onto the Trimble Geo7x and loaded into ArcGIS for Windows Mobile it prompted me for a User Identity. So it does look like the issue seems to be stemming from the TrimbleSessions/Positions.

Isaac... Just to remove Positions from the equation, do you get the same behavior if you create a mobile project using a mobile cache that does NOT have a TrimbleSessions layer and use that on the Windows Mobile device? You can also temporarily move the PositionsMobileExtension.ame file out of the \Program Files\ArcGIS Mobile\10.2.1\ folder to prevent the field-side extension from loading. You will get a prompt saying it can't be found as the .amp file still references it.

IsaacGant

Hello All,

We are having an issue with the User Identity layer in a Mobile Project not functioning properly on a certain device. Using Trimble Positions Desktop Add-in 10.3.0.2, Trimble Positions Mobile Extension (and Mobile Project Center Extension) 10.2.1.1, and ArcGIS Mobile Project Center 10.2.1.0 to create a Mobile Project using Mobile Services that were published from a Server Enterprise Geodatabase via ArcGIS for Desktop 10.2.2. The device that is having the issue is a Trimble Geo7x Handheld unit with ArcGIS for Windows Mobile 10.2.500 installed. We have setup a User ID feature class layer that is meant to record the Identity of the user that is collecting data for that current session. Whenever we open the project on the Trimble Geo7x unit, the system never prompts the user to select or create their Identity and then opens the project for data collection. If we open the project with ArcGIS for Windows Mobile (Version 10.2.1.0) on our desktops or Windows tablets (both run Windows 7) then the User ID layer works perfectly, prompting the user to select their identity or create one if they are a new user. Normally the program would not let the user continue to the project without selecting or creating their identity first. Has anyone else experienced a similar problem? Any help or suggestions would be greatly appreciated. Thank You.

I did remove the spatial index, but the only thing that changed originally was that I received a message stating:

"Check finished; No available sessions.

1 session in other projects remain."

I tried checking in all of the projects that I have worked on, and finally was able to see other sessions, but had no luck actually seeing the session points as we should. I just saw the polygon in the TrimbleSession Feature Class.

This morning, after shutting down PC last night, I was able to see the new Session, but I still have 8 sessions I am unable to see. They are all from last Friday in the same project. ArcGIS Mobile/Trimble Positions errored out several times and closed the program, which explains the multiple sessions. However I can't actually see the sessions as I am supposed to through the Trimble Positions Desktop add-in, I just see the features in the feature class.

-------------------------------------------------------------------

FYI - I am in contact with a Support Technician also. She wanted to make sure I am checking it back in with the same MXD, which isn't the issue since I have been using the same MXD for all of the mobile caches I have created for this type of project.

This could be due to an issue with the spatial index. Try removing the spatial index on TrimbleSessions and re-attempting the sync.

As a note to others who read this thread, I'd suggest using your Trimble dealer and Trimble Support as your front lines for Trimble Positions questions, ahead of posting here. I don't believe this forum is monitored regularly by Trimble although you can certainly make the argument it should be.

We are using Trimble Postions 10.2.1.1 with ArcGIS for Windows Mobile 10.2.1, after creating the Mobile Cache with Positions Desktop add-in 10.3.0.2.

I don't have a problem creating the mobile cache and deploying it to the field, however when I Synchronize the Mobile Cache after collecting, I get the error: "Error posting updates for TrimbleSessions layer." All of the collected features are automatically posted to the geodatabase, but we want to be able to see the point clouds associated with each feature. We have the project set up for Real-Time Corrections + Post-Processing. I can't even see that there was a session at all.

Is there a setting I need to change, or is someone else experiencing the same issue?

Hi Alison,

I just got off the phone with ESRI ArcPad support and they had me move my project to a new folder location. I moved it to my desktop and it seemed to work.

Also, my apologies to everyone reading this thread as I just realized I posted an ArcPad issue on the Trimble Positions thread.

I haven’t seen this one. Do you get the same message with other ArcPad projects? Have you tried an uninstall/reinstall?

Hello all...

I have a new question.

I am trying to use Quick Fields, for the first time. I have exported a project with a point feature class for use with ArcPad. I have opened the project in ArcPad on my pc in order to create a Quick Field that adds a sequential ID. I have turned on Quick Fields. I have gone into Design Mode. I click on the Quick Fields button and then click on the Add button.

Here is where I have a problem:

When I choose "Layer," I get this error...

I have tried closing every program on my computer except for ArcPad and I still get this error. Could this be because I am using a personal geodatabase instead of a file geodatabase?

I'm afraid I don't understand what this error means.

Any help would be appreciated.

Angela

Hold down the Control key on the keyboard while you click to remove the project and that will override that message. Hope that helps.

Alison

Thanks Alison!

This worked perfectly.

Yes, it worked!

Thanks a bunch!

Hi Miles,

Sorry for the delay here. So if the Seiler station was failing to download, you might try again now that it's been a little while. Maybe it was just too soon? Those are usually pretty good I thought, and you might call Seiler directly if you can't get them to work.

The accuracy may be a result of the distance to the base station (or your receiver, and I don't see anywhere what that is). If it's really far away, you just shouldn't expect high accuracy estimates. The base station distance that you refer to above is only referring to the difference in datums and really shouldn't affect the accuracy estimates. You can go into the base provider properties when selecting a base station and on the Reference Position tab, you can choose to use the reference position from the base provider, but that's not going to improve your accuracy estimate.

The only way to know for sure that you are getting decent accuracy and that there is no datum shift occurring is to collect data on a good survey monument.

Thanks,

Alison

Hello all...

I hope I am posting this in the correct place.

My organization just started using Trimble Positions with ArcMap 10.2. I am able to check out data (for use with a Trimble Geo7x), collect GNSS data, and check it back in. However, I have some projects that I created when I was getting to know Trimble Positions that I cannot remove. I wanted to clear out the Trimble Positions Desktop Administration window and remove several old projects. I keep getting this message:

Project [xyz] cannot be removed as it has active sessions.

I have already deleted the project files from my Geo---I hope that was not a mistake. I assume that those sessions are flagged as "active" somewhere in the TP Jet database, but I have no idea how to change that.

Does anyone know how to remove projects with active sessions?

Thanks a bunch!

Angela

Thanks Alison, that does help....just wish the Positions setup documentation would have filled me in on the changes, and not instructed me to enable GNSS.

The data that I am not able to check-in was created using TerraSync, before I had any of the desktop software (or even a desktop for that matter). I will try to check-out the schema for these features and re-collect the data....sure glad I wasn't gathering tons of stuff while I waited 4 weeks for the new HP Workstation!!!

As far as differential correction accuracy....I tried using the nearest base station for my test data (a Seiler Institute one), but it continued to give me download failure warnings. Then, I tried with the GLONASS only stations, and that at least got the data corrected, but the accuracy was mostly in the 2-5m category....and the base station distance was 1.03m. Is there a way to correct the data using the base station datum or projection vs. the data's?

Thanks again.

Miles

Hi Miles,

The latest version of the Trimble Positions Desktop Add-in does not have that GNSS Enabling button anymore in the admin window. That is really only required when using the ArcGIS for Windows Mobile field software, so it was removed on purpose to try to resolve some of that confusion. If you set up a project for ArcGIS for Windows Mobile, then you will see the GNSS Enabling option in there.

On your check-in, it sounds like maybe you were collecting data in ArcPad and then trying to bring it in with the TerraSync tools? Or maybe that you had collected data in TerraSync that was just created on the handheld and not created from Positions? That won’t work to check in. In order to check in TerraSync data to Positions, it has to be checked out from Positions. If you were using ArcPad, you could use the QuickProject check-in instead.

And yes, Positions does not allow differential correction with multiple base stations the way you could in Pathfinder Office. You will only be able to correct against one base station at a time.

Hope that helps.

Alison

Good morning everyone...I just got everything setup with Trimble positions Desktop Add-in. I have ArcGIS 10.3 ad use TerraSync in the field on out Trimble Geo7X.

First issue is that I do not see the "GNSS enabling" option in the Desktop Administration dialog. This one has me pretty stumped

Second, I am having trouble Checking-in data collected using the generic TerraSync feature classes. I collected these data last week, prior to having our new workstation and the software. Please see the attached screenshot for the error I get when trying to check-in any SSF using the generic TerraSync features.

Check In Error screenshot.jpg

I can export those data to SHP files and get those opened in ArcMap, but then I am unable to correct them.....I was able to export some schema from our data model to TerraSync, and collect field data with those attributes, then check those in and successfully correct them (sort of - see #3).

Third, when I corrected the data from the test file, I was only able to select one base station, and it did not give me enough accuracy (based on what the unit was expecting). What is the best way to setup Trimble Positions for differential corrections? And, does this have something to do with not having the GNSS Enabling option?

Thanks,

Miles

BartPouteau

I'm having an issue with the Compatibility Testing on the Enable GNSS screen. When I run the test it tells me to "Please define a datum transformation for feature class [xyz]." I've already set a transformation in the ArcMap data frame as well as the Positions Datum Transformations dialogue (says it's for ArcPad and I'm using Mobile but figured it couldn't hurt).

I'm not aware of anyway to set a transformation to one specific feature class in ArcMap without actually modifiying the source data which isn't and option... am I missing something?

Thanks.

Bart

Hi Darryl.

This works now. See posts below for explanation. There is also a link provided by Jorge Orellana that pointed me in the right direction.

Good luck!

James

Gold!!! thank you for finding and posting that!

This was the remedy! And here was my post back to that forum.

Fantastic!!!

I have been working on this since Monday!

Our set up is: A GeoXT 6000 running Windows Mobile 6.1, ArcPAD 10.2 for Mobile, Trimble Positions Add-in for ArcPAD 10.2.

On PC: Windows 7 64bit SP1, ArcGIS Desktop 10.2, ArcPAD 10.2 for Desktop, Trimble Positions Add-in for Desktop 10.2.

I was receiving the same SQL error:

In order to remedy this solution I had to remove the QuickField Applets from the GeoXT 6000's program files.

Located at DeviceStorage/Program Files/Arc Pad/Applets

I created a sub directory called quickFieldBackup and moved all of the Files that started with QuickField into this.

Everything works great after that!

Thank you a ton!

Hello again,

That is just crazy. I was always told that only file geodatabases were the

only format that the GPS software worked with. I will look into it if I

find out any different I will let you know.

HI Darryl,

I am pretty much 99.2% certain that I had this working up until about 4 weeks ago.

I am running Arc Desktop 10.2.1, ArcPAD 10.2 and Trimble Positions Arc-pad add-in for Windows Mobile 10.2.

I am exporting layers from Arc Desktop via the Trimble Positions for Desktop Add-in.

I am not sure what happened but one day i just started receiving this error on every thing that I exported to ArcPAD that was tied to a SQL database connection (SDE?)

Anyway if you are certain that Trimble Positions Desktop Add-IN won't export to ArcPAD correctly when using an sql database, please let me know again.

But like i said, I am pretty sure I had this going once and I don't know what changed.

Thanks!

James Hickey

DarrylSanchez

Hello James.

Welcome to the GPS world. You are right to say that it doesn't work. The

reason is that the technology only allows file geodatabases at this point

in the game. However, I anticipate that it will change and add other data

types.

I am having trouble when using and SDE geo database. After export, when i open the map on a GEO XT 6000 windows mobile 6.1 in ArcPAD I receive the attached error message. If I use a file geodatabase locally then I don't receive the error. I need to use SDE geodatabase in SQL.

Any ideas?

Thanks.

JosephRigley

I apologize for squeezing sour grapes in the thread, but since you asked... In terms of problems I am having with Positions, it's all over the place, similar to all the problems others have posted in this thread (exporting cache, synching cache, correcting sessions, updating features). Every time someone goes into the field with it I face a wrestling match at the front and back-end of the field session troubleshooting steps that failed for a wide variety of reasons, most unknown. Trimble has had plenty of time to get these things working better. That, combined with an overall dissatisfaction with Positions in ArcGIS Mobile workflow, 1996 GUI, and mystic error handling. Some of these things are surely a result of or made worse due to integrating with chronically sub-par ArcGIS software (esp the workflows), so I don't blame it all on Trimble.

I may just be a tough customer, but reading the rest of this thread I would think not so much.

DarrylSanchez

Joseph,

Sorry to hear to that you had frustrations using Trimble positions. I have

had good experiences with this software but now have moved on to ArcGIS

Mobile for Windows 7 running on Trimble Yuma 2 Tablet PC.

I am curious what exactly what you having problems with. I know Allison

Walker and she is very knowledgeable. I took some Trimble classes from her

and she was a wonderful instructor.

Thank you, Alison Walker!! Deleting the spatial index on the sessions feature class fixed the problem I was having today with sessions not syncing.

Also, I usually have to finish sessions that are for some reason open on the Trimble before copying off the the mobile cache or I run into problems.

I have to say that this Positions software has a pretty even cost:frustration ratio (very expensive, very frustrating), it's some of the worst software I've ever had to use.

EricJohnson

The lack of a failure notification is really odd.

I recently experienced failure to update notifications when trying to update corrected polylines in a geometric network.

Is anyone aware of a workaround for this? I am planning on writing a script to create the network with the rules anyway, this problem makes the script more urgent.

kg76

I've got a new problem and I'm trying to figure out whether it's an IT issue or something I did.

I use ArcGIS 10.2 + Trimble Positions Desktop + ArcPad extension.

Up until recently everything was running smoothly, I was able to check out data, collect data, check it in, post process it, and update my collected features to a geodatabase.

Recently, the last step in the workflow - the "Update Features" step - fails. Actually, it doesn't fail, it just doesn't work. I press the button and nothing happens. This is only occurring for one geodatabase that I use. Others will update, no problem.

Has anyone experienced this before?

TrentReeder

Has anyone had any luck determining why Trimble Positions can't find new sessions? I am having the same problem as cfoster15 and TrentR. I can synchronize a mobile cache and get the features to import that way but I need it to recognize the sessions in order to do post-processing. I have made sure everything is in the same projection, the MXD and project are associated, etc.. I'm not sure what's wrong.

Good news and bad news... Good news, I was able to get a test project to find my session data only after going into Positions Desktop Configuration and creating a new Jet DB. Bad news, it only worked that one time and I am now back to Positions not being able to find any new sessions.

I would suggest going through your log files to look for any glaring issues. Here's where you can find a number of them (locations on your machine may differ):

C:\Users\<user>\AppData\Local\Trimble\Positions\10.1
C:\Users\<user>\AppData\Roaming\Trimble\Positions\10.1
C:\ProgramData\Trimble\Positions\10.1

Hope this helps!

JoshuaJacomb

Does anyone know if Trimble Positions can be run in conjunction with ArcGIS for Windows Mobile running on a full Windows 7 Tablet (Panasonic)? Based on Trimble's literature the Positions extension does not operate on the full Windows OS, but I was curious if anyone had tried this approach anyways. It would be nice if they would release a version that was identified as compatible considering that ArcGIS for Windows Mobile can be run on a full Windows OS. Thanks in advance for any responses.

Hi Chad,

A couple things can cause this, but the one I see most often is the Spatial Index causing trouble. Try opening the feature class properties in Catalog, go to the Indexes tab and Delete the Spatial Index then try to sync again.

Hi Kim,

Wanted to let you know that the Invalid Geometry issue when collecting lines with nested points has been logged as a bug by Trimble and is expected to be resolved in the next release, hopefully before the end of the year.

Alison

Hi Kim,

Do you use nested points when collecting your lines? Can you describe that workflow? Are you streaming lines or collecting vertices? And then when you stop to collect a point, do you pause your line and then continue when you are done with the point feature?

Thanks,
Alison

Thanks for all the info Kim! I'm glad it worked for you today, but as you said, that just seems to indicate that none of your settings or your workflow or database would cause the problem. I think it must be in the software. I'm working with Trimble on this, and I'll let you know what I find out... might be Tuesday before it moves forward. In the meantime, if you get anything new, let me know.

Alison

KimHonetschlager

Alison,

I misspoke on the "View Position" issue. When I check the data into my mxd and select "View Features" I see the "Invalid geometry" error, but when I click on one of the arcs it displays in the map and its position is reasonably good. It has geometry. When I select "View Positions" for that arc it doesn't show any positions. So it does sound like it's the same problem that you are seeing.

I collected again today. Collected about a dozen arcs in the same area with the same settings and I get no "Invalid geometry" errors. I did get an "insufficient accuracy" error on some of the arcs, but I marked those as exceptions and corrected the data successfully. I should loosen up the accuracy before I collect again, but I don't think that's related.

Still grasping at straws. I tried collecting with or without a new checkout & it doesn't seem to matter. I took the spaces out of my folder name and apm name, but I don't think that's it. I've got Maplex turned on in the mxd - that used to choke ArcPad/GPS Correct/GPS Analyst, but that's been the same on all my recent sessions. I tried collecting streaming vertices from the main editing tool bar and from the one at the bottom of the screen; makes no difference. I've collecting a point within the arc by pausing the streaming vertices versus just collecting an arc; interrupting doesn't trigger the error. I've tried long and short arcs, collecting many arcs or just a few. No dif.

I'm using the Trimble ArcPad Extension protocol in GPS preferences. Log GNSS to SSF is turned on in the Trim Positions Setup>Logging Settings. Real-time settings are: Choice 1: Integrated SBAS and Choice 2: Use Uncorrected GNSS. Since I'm post-processing I should probably just use uncorrected GNSS, but these settings have been consistent across sessions. It's possible that I changed some setting that triggered the error, but I'm not aware of having done so.

I have not tried a QuickProject. My database is simple: an arc feature class (trails) and a point feature class (trail points). I used it with GPS Correct/GPS Analyst last year. I'm collecting out in the open for testing purposes. I don't have an external antenna.

I'm open to suggestions!

Thanks Kim,

I guess the first thing I should have asked is if you are setting any accuracy requirements when you set up the project. These guys are not, but if you are, then that may be the problem.

So these users that I am working with also had GPS Analyst on their computers recently, and given the other problems I have seen with that, I wonder if there might be something there. I will investigate this one further and see if I can come up with something.

Might not be the same issue though because when they click on a feature and click View Positions, nothing is listed in the window where you should see information about all the individual positions. It is just blank... which explains why they get the Invalid Geometry error, but not why it happens to begin with.

The one thing you mention is that with a smaller amount of line features, it worked fine and when you collected more, then you got this issue. These users are many times collecting 30 or more line features in one session, and I wonder if this might be causing problems? But honestly, I'm just grasping at straws there. Wondering if you could reproduce the same behavior again.

Trimble asked if you could reproduce the issue using a QuickProject instead of your own database. Then it is easier for them to rule out an issue with the database itself.

I'll keep you updated on any additional info I can dig up.

Hi Kim,

I have a couple users having the exact same issue, and I have not been able to get to the bottom of it. Maybe we can compare and see if we can find the common thread that might be causing this?

- What is your OS? I initially thought it had something to do with Positions' trouble running on XP.
- Were you previously running GPS Analyst on that computer?
- Were you running an older version of Positions Desktop at some point? What version are you running now?
- When you click on one of those Invalid Geometry features, and then click the View Positions button, is there anything in there? Or is it just blank?
- Is this happening even before you differentially correct? Or is it only after differential correction?

I would be very interested in any info you can share.

Alison,

Here are the specs: Win. 7 Professional. Yes, I previously ran GPS Analyst, but this is the first version of Positions that I've used. Positions Desktop Add-In v. 10.1.0.3.

The data are definitely there. When I select an arc and "View Positions" it shows up. On my first session I collected just 4 arcs, but they all imported without error. Then I collected 8 arcs over 2 different sessions (I don't think I changed any settings). Only one arc imported successfully, the others all have the "Invalid geometry" error. I thought at first that it was because I had interrupted the streaming to collect a point, but that didn't prove to be the problem. I get the errors before I differentially correct. The points I collected all look fine.

Thanks,
Kim
