Has anyone used a Leica GS15 receiver with Collector?

MTorres

I'm using an Android smartphone for Collector (Samsung Galaxy S5). The phone pairs via bluetooth just fine with my receiver but Collector is still showing my location to be about 15 feet off from where it is. Yes, I told Collector to use the receiver and not the internal/phone location GPS chip. TIA

Megan-

We have spoken with a few customers that have used Leica GS15 receivers successfully with Collector.

How are you determining that you're 15 feet off?

Megan,

I'm assuming you have gone through these steps?

Thanks for the suggestions. Here is my final solution: Use the android app "NTRIP" by Lefebure as a mock location provider. Set Collector to use internal location/GPS. Use the Leica CS15 Controller to initialize/start the RTK output in the GS15 GNSS device. Leave the CS15 Controller turned on and carry it on my belt because if I turn it off the GS15 stops sending the RTK corrections. Use the android/Collector to capture centimeter accuracy data. Tips: the GS15 and NTRIP app require separate RTK logins.

The one downside of the approach above is that you will lose some of the GPS metadata if you're storing it on the features you're collecting.

We has worked with some folks in the UK who were using the GS15 and they were able to get this working once they had updated the firmware of the GS15 to 5.0.1 (which may not be the most recent). Older versions were sending an invalid NMEA stream which presented Collector from reading certain sentences.

This is great news, our company has several GS15 units. It would open up a lot of internal opportunities for our department if we could use existing hardware.

Doug,

I have looked into this and so far (beta testing) I haven't run into any problems. As long as I use the GNSS metadata tool to create the fields in my feature classes, the GPS metadata is stored correctly. I'm using firmware version 7.51.

M Torres Hello, I am trying to do the same (connecting a GS16 and receiving NMEA messages to use as a mock location provider with the Android app "NTRIP" by Lefebure). Do you happen to remember the settings you had or if you did anything special to make the connection work? With my current setup, I am not receiving data on the Android app but it is working on the Windows app. However, it would be preferable to use the Android app because of the mock location provider option that is not so straight forward with a Windows tablet.

Here is my setup :

- GS16 with NMEA license (v8)

- RTK Port = BT1

- NMEA Port = BT2 (outputs set to GGA, GSA, GSV, RMC, VTG, GST)

- Bluetooth connection to the GS16 with either an Android phone or tablet (Getac ZX70)

- RTK connection to a public network (MERN)

→ However, no NMEA messages received and a waiting warning for GGA displayed (see image)

Hi Alice. Are you using the same login credentials for your RTK reference network on both the receiver and the NTRIP app?

When I had the same issue as you, I had to get separate login credentials. One login for my GS15 receiver and another login for the NTRIP app.

I’ve also included screenshots of my settings here for you. Hope this helps!

Hi again!

Thank You for the prompt response and for the screenshots!

I thought the GS Receiver was getting its RTK reference from the Bluetooth connection with the smartphone/tablet but I am understanding is that it is not since you are using another login credential.

When I tested the connection, I used a Raw TCP/IP connection so I had no login credentials. I used the reference table below for the IP adresses/ports and selected the Data Stream format accordingly.

I will try using different login credentials to see if it fixes my issue. Thanks!

Hi Doug,

Do you have any inputs on how the customers connected the GS15 with ArcGIS Collector? Did they created a profile in Collector? And do you know if they successfully received the data from NMEA sentences (quality : hdop, vdop, pdop etc)

Thank You!

JaredTaylor

Did you make sure you set up a location profile for the unit in your profile in Collector? This is a setting above where you select an external GNSS Unit. This is an important step so that the transformation from the NMEA stream translates your position into WGS84 web Mercator which is what the Esri basemaps use. It sounds like this may be what you are experiencing. Just something to be aware of.
