Does anyone know if you can use the Trimble Viewpoint RTX correction service with a Trimble R1 GNSS receiver and Collector? I'm having trouble finding any documentation on it. Trimble mentions that it is compatible with all of their data collection apps like TerraFlex but I'm not seeing any other non-Trimble software on the list.
Thanks!
They are working on that !!
Regards
Alberto
Yes the Trimble R1 is compatible with collector. It takes over your internal GPS on the mobile device that you are using collector on. We just completed testing with the R1 and collector and we see a reliable submeter solution and we even see sub 2ft because you can use an app developed by Trimble called "GNSS Status" to dial into a real-time base station if one is available and receive that correction.
Sorry Amanda I replied to Alberto and not you
Hi Mark ,
You Know if there is a document available that described the steps to configured the R1 with an IOS device (Iphones,Ipads)?
Regards,
SBAS or real-time base station will work with Collector. But currently RTX correction source doesn't work with Collector.
Thanks Miaogeng - Do you know if this is something that will be added with future releases of Collector?
If a company needs the data measurements instantly, because the positions are used in related workflows right after the measurements have been performed, how would you then do the transfer of data?
As long as the device that you have collector loaded on has an internet connection you should be streaming your data directly back to the office. One thing to remember is publish your feature service in WGS84. As long as collector recognizes your rover then collector understands Trimble rover location.
Thanks Mark, so that means that it works in 'the same way' as using the GPS in the mobile device. I'll try it out. Do you also know if is possible to use a Trimble Rover with Collector?
By Trimble Rover are you talking about a Trimble R Series receiver? If so yes we have connected our Trimble R8 RTK rover with our android devices and collected High Accuracy single baseline correction GPS using our statewide VRS network. We cannot connect the R8 to the IPAD though. Just remember to download the Trimble GNSS status app to get the RTCM correction functionality.
Apple's core location services rounds to the decimeter level for elevation from what i have seen using the EOS GNSS receiver. Does the Trimble App override the core Apple location feed and allow points to be stored to a lat long precision of 8 decimal places? Or does it get rounded up?
Dan Allen. I have no idea about EOS GNSS. As i know something for sure is that you can't say that you can achieve that accuracy worldwide. I know in Europe with R1 you can get 10 cm . But in different continents depend from coverage of the satellites, type of satellite and correction signal. So same is even for iphone. Depend from your location. 🙂

Until told otherwise, or a new update, it appears Collector just is not setup to collect high accurcay GPS data, even if you can connect to a bluetooth GPS receiver. It does not store a Z elevation even if the feature is z enabled, and it does not store PDOP, horizontal, vertical precision values typically associated with High accuracy GPS.
I am hoping someone from ESRI can clarify, and or provide a status update on better support for RTK GPS in hopefully the upcoming release of Collector.
Mark,
How did you connect your R8 to android bluetooth/collector? I tried connecting our R10 to android. It pairs in bluetooth and shows up in the Trimble GNSS status app, but it fails and gives an error message when I try to select it as the receiver in the Trimble app. Is there some sort of configuration?
Thanks
No it would just show up in the GNSS status app and I could connect.
Did you setup some sort of bluetooth connection first to your R8 using Trimble Access, or did you simply just select the R8 in the Android bluetooth list and pair with it? It doesn't make any sense that the R8 would work, but the R10 wouldn't. I must be missing something simple.
Dan
Did you go into android developer options and allow mock locations. Don't think this would make a difference. I do also have trimble rtx installed on my android phone that I had set up prior to testing the R8 for other purposes. That would be the only things I can think of. My workflow Bluetooth connection to R8 through android bluetooth. Go to GNSS status and connect. I tried it with a Leica GNSS receiver and I could bluetooth, but it would not connect through GNSS status either. Sounds similar to what you are running into. Not sure what would be causing this.
Thanks for the info. I have mock locations enabled. If I use the RTX app I can bluetooth connect to the R10 and see satellites. Oddly if I add the R10 as a bluetooth device through android first, the RTX app won't connect. If I delete the Bluetooth pair, then open the RTX app first, it will initiate a new pairing with the R10. I am curious if the new "add trusted device" in Android 5.0 that pops up when you make the connection is messing things up. When i try this same procedure with the GNSS app (unpair, open app, make new pair through app), I get the popup for entering the password, but after typing in 0000, it looks like it is going to work, but then I get a failure message.
I wifi connected to the R10, and logged into its ip address . There are a lot of configuration options in there. I am sure it is just a check box someplace that is keeping this from working.
I contacted Trimble, and our R10 is about 5 firmware versions out of date, and updating to current should fix the bluetooth connection issue.
Great!! The firmware, yes we have been burned in the past with firmware so
always good to run upgrades periodically. Hope this works for you.

Dan,
Thanks for your feedback. From Collector for ArcGIS v10.3.4 is out | ArcGIS Blog , you can see we are working on better support for high accuracy solution. The initial release v10.3.5 will include the following capabilities:
Hi, I've been using the Collector App with Trimble's R1 to collect point data in the UK.
The R1 is receiving corrections via Trimble's Viewpoint RTX service.
I have just read the following page (Using GNSS Receivers with Collector for ArcGIS | ArcGIS Blog)
which seems to suggest that the ViewPoint RTX service is not using WGS84, but rather a national reference frame (ITRF).
Is there a chance that the points I am capturing with the Collector App are not in WGS84 as I first thought?
I have been extracting and projecting my points into British National Grid, and finding that they all appear approx. 5m South of where I had expected..
Many thanks.
The difference between WGS84 and ITRF is quite small. That should not be the reason of 5m shift. Can you share more details about how you extracted and projected your points into British National Grid? Also how do you configure your webmap, such as basemap, feature service spatial reference?
How do you retrieve the coordinates collected using the Collector app the GNSS utility app and the R1 GNSS receiver if you are not using an internet connection outdoors? Where can i download the coordinate data?
