Request to add external GPS receivers to the docs

If you have external GPS that is not listed in the official documentation, please let us know as comment to this issue and we will add it... (OR create Pull Request and add it yourself :))

Martin Trimmel on Slack: "Hi! I tested the Leica GG04plus. Works perfect on Android. On iOS it was not possible to get the antenna information into the input app."

Hi, I was able to connect Input 1.3.0 (Android) to a an Emlid Reach M+ (not a surprise since Reach RS+ is listed) using several methods:

direct Bluetooth connection
Android mock location > Bluetooth > GPS Connector app
Android mock location > Wifi > NTRIP Lefebure Client
No luck yet with iOS... However, since NMEA over TCP seems to work, I would be happy to test an option within Input for a direct connection over TCP !

For reference, connection over TCP is MerginMaps/mobile#1893

I’ve been using the Garmin GLO 2 on an iPad with the Input app without trouble for a couple months.

Hi, we are using the UNI-GR1 marXact GPS receivers on Android tablets with the Input app, works perfect!

Tested with Emlid Reach RX https://www.linkedin.com/feed/update/urn:li:activity:6993131837707452416/ on android

We use Carlson GNSS receivers (Brx7 & XML2) to take measurements in Mergin Maps, which works well on Android! In combination with Carlson Layout, this application can overrides the mock location of the tablet's internal GPS.

I have tested the Carlson Brx7 directly via Bluetooth connection, the Brx7 has an internal NTRIP client to receive corrections.

I have used Geomax Zenith 06 and Zenith 60 receivers with Geomax X-PAD Android application.
You need to request a GNSS Mock license from Geomax ( it is free of charge) and use the "Mock GNSS" option in the X-PAD application.

Could you please add these devices from ArduSimple?

Thanks!

@jolivart

@jolivart Sure! Could you specify if these devices work directly with Mergin Maps mobile app or if they need some other app (Android/iOS) for NTRIP / mock location? Feel free to include any useful info about the setup :) Thanks!

All the devices can work directly with Mergin Maps.
They can be used in parallel with GNSS Master app for Android to get RTK corrections.
We have prepared a tutorial:

Thanks!

Can you trimble r4s. Receiver?

Can you add trimble r4s receiver?

Hi @gef431 , could you please specify some details about the usage? Does it work through Trimble Mobile Manager app (like R1 and R2) or something else? Do you use it on Android or iOS? Thanks!

Yes. It work with TMM.Can I configure the application to use TMM position?

I have a Spectra SP100 (Trimble) GNSS receiver. I'm using Trimble Mobile Manager (TMM) to connect to the receiver and to TERIA as the NTRIP correction service. I also enabled Developer Mode in TMM so I could activate the Android Mock Location feature through Trimble Mobile Manager.

My goal is to use the SP100 with Mergin Maps.

However, when I select "Internal receiver" in Mergin Maps, the positioning accuracy is nowhere near centimeter-level. Instead, it ranges between 20 and 80 meters, as if the app is using the phone's internal GPS rather than the SP100.

If I select "Internal receiver (fusion)", I don't get any location data at all—the app doesn't display any position.

Could you help me understand what might be causing this issue and how to configure Mergin Maps correctly so it uses the SP100 with the RTK corrections provided by TMM? Even with GNSS Master it doesn't work. Dans directly by bluetooh, I don't even have the coordinates

@HydretudesOI

Hi @HydretudesOI, I haven't used TMM as a mock position provider myself, but we're adding native TMM support to the mobile app. The upcoming release introduces a new position provider connection method for direct communication with Trimble devices, see MerginMaps/mobile#4641.

Once it's out, I'd recommend switching to this method instead of the mock workaround.
