Is Collector compatible with a Trimble R1 GNSS receiver using the Trimble Viewpoint RTX correction service?

AmandaRenner — Tue, 30 Jun 2015 21:30:14 GMT

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!

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.

Hi Mark ,

You Know if there is a document available that described the steps to configured the R1 with an IOS device (Iphones,Ipads)?

I don't have any good document that I can point you in the direction of. However it is fairly simple as the R1 connects via bluetooth, and I have seen it work from our vendors on IOS devices. The trick to getting it to pair is that you hold down the power button on the R1 until it flashes blue, then if you have the "GNSS Status" app download it should show up in devices. Then you just hit the plug and it will start using the R1 as the GPS.

SBAS or real-time base station will work with Collector. But currently RTX correction source doesn't work with Collector.

These are the results of accuracy checks on 3 known control monuments in our county. The blue dots are the control monuments and the green circles represent 1, 2, and 3' distances around that point. The pink points are the collected GPS coordinates using the R1 and the GNSS status app. One thing to remember is to make sure that your published feature service is in WGS 84 coordinate system, then you can reproject to whatever coordinate system if needed.

What is the correction source do you use?

I used a real time vrs network correction Iowa DOT provides this service. I connect to the closest base station through Trimbles "GNSS Status" app and it provides that single baseline correction. Definitely should be tested in every situation, but these results made us happy.

Thanks for your assistance on this Mark. I found this description of how to connect Collector to the R1:

How do I connect the R1 to my iOS device for use in Collector?
Getting your iOS device connected to an R1 through Bluetooth may seem intimidating, but it can be achieved through a few simple steps.

Download the Collector for ArcGIS app and Trimble GNSS Status Utility off of the app store. Both of these apps will be free to download.
Connect the R1 receiver to you iOS device with Bluetooth. On the R1, push and hold the power button until the left LED light flashes blue. On your iOS device go to Settings>Bluetooth and turn Bluetooth on. The R1 should now show in your Devices list as GNSS:<last five digits of the R1 serial number>. Tap on the R1 in the Device list to connect.
Open the GNSS Status Utility. If necessary, tap on No Receiver Connected. Select the R1 and tap on the plugs to establish the connection.
If you are interested in using the SBAS corrections for higher accuracy, you will need to set it in the GNSS Status Utility. Tap Menu to bring up your options and go to Real-time Config. Edit the setting to change it to SBAS. Now, if you go to the Home screen, you should start to see your accuracy decrease as it connects to the SBAS satellite correction. If you want to see the SBAS satellites you are currently tracking, go to Detailed Status in the Menu. You will see a satellite count under Satellites by System.
The GNSS Status Utility automatically creates a mock location for Collector to use. When you open the Collector app, it should be connected to the R1 and no settings have to be changed. If you want to test that you are connected to the R1, set it on the ground and walk away with your iOS device. Your position in Collector should stay stationary as you move.

Would you say it is accurate and/or helpful?

Thanks again,

Thanks Miaogeng - Do you know if this is something that will be added with future releases of Collector?

That is it for the ios platform, with androids you have to go into developer options and changes some settings, but there is a lot of help out there on how to establish mock locations.

This should get you up and running, and I have not tried SBAS. We have the free VRS real-time service available through the DOT so we always try to use this. Just wanted everyone to know that the results above are not from SBAS.

AmandaRenner — Fri, 17 Jul 2015 16:23:12 GMT

Thanks for the clarification. We sometimes work in IA and probably other states correction services so we might be able to take advantage of that until the RTX service works.

We have also tested our Trimble R8 survey accurate unit and have found it

to collect even better results through collector using the GNSS status

app. The R8 does not bluetooth to our IOS devices for some reason though,

but android is fine. Have you tried using GNSS status and an R1 with the

built in RTX. I would of thought it would of collected everything based

on the mock location, and when using GNSS status the GPS should be

whatever the connected device is. You could always talk to your vendor,

we use Seiler and they are starting to get results for the R1, which

doesn't have a lot of testing since it is so new.

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?

Data measurements from the Trimble Rover are streamed via the Trimble controller directly to the database.
The Collector App receives the data measurements from the Trimble Rover.

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?
