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

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.

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 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.
