Setting up a correction link - Arducopter integration?

Hello together,

i have a cube orange flight controller setted as arducopter, remote controller i´m using the here link.
Aditionally i´m using the telemetry this module on my orange cube FC:

In the installation guide, is described that it´s possible to use the telemetry radio as a carrier for RTK corrections. Is that necessary? What is the sense for this?
I have a reach M2 module as rover and a Reach RS2 as base, connected with EMLID Lora Radio.
https://docs.emlid.com/reachm2/ardupilot-integration/#setting-up-a-correction-link
i´ve tried to set this, but this menue is not active?
In the EMLID documentation, does it say that MAVLINK communications has to be switched off first?
But where do you have to do that in the Mission Planner menu?
And if you do that, does the previous telemetry module no longer work?
Do you have to reactivate MAVLINK communication then?
How i must proceed?

Hi Fred,

This option is usually used for optimizing the number of connected devices. It’s easier to supply the Reach M2 module with corrections via the UART connection to the autopilot. This way, you don’t need to use additional modules to receive corrections.

You don’t need to use the LoRa radio for receiving or transferring corrections if you’re planning to embed the corrections in the telemetry link.

You’ll need to connect only telemetry radio to the GCS. MAVLink connection to autopilot should be disabled otherwise it won’t be possible to change radio settings.

May I ask you if you have loaded the radio settings prior as described in the guide? Have you disconnected the telemetry from the autopilot prior to the configuration?

Hi Polina,


You mean, i can unmount the LoRa communication module?
The RTK communication between Reach RS 2 Base and Reach M2 Rover (in my copter) can communicate trough my installed RFD Long Range Telemetry module completely, without LoRa?
Can i completely remove the Lora module from the copter?
Since i´ve intrerupt the communication with the Lora module, i didn´t see any signals from the reach RS2 in the state of the rover M2.

Thank you!

Hi Fred,

If you’re planning to embed the corrections into the telemetry link, there is no need to add or use LoRa radio module. The autopilot should transfer the corrections to the receiver via the Serial connection.

Yes, you can.

Yes, the main idea is that the base sends corrections to the GCS which transfers them to the autopilot via a telemetry link. This helps reduce the number of hardware components introduced to the drone.

If you’re planning to send the corrections via the telemetry link, there is no need to use the LoRa module.

May I ask you if you have successfully configured the correction link between the base and GCS?

but if i didn´t use Mission Planner? i wanna use instead UGCS as autonomy software?

What do you mean exactly with GCS? Mission Planner?

you mean if i get GPS injection into the mission planner? Yes i get signals.

Hi Fred,

The functionality of embedding the telemetry radio as a carrier for RTK corrections is available in the Mission planner only. If you’re using another configuration software, you won’t be able to use this feature.

Yes, I mean the Ground Control Station, probably laptop with a running Mission Planner.

Yes, that’s what I meant. Could you please share the screenshot of the Status tab of the Reach M2? It’ll help us check if Reach can send the corrected solution to autopilot.

But i´m helpless, i don´t undestand what i must do to get signals from the scond GPS…

Dear Polina, this is my setting in mission planner:

What do you suggest to set here, to work with reach M2?


first it was setted to 0: no inverted, but the same problem: no signal to GPS2
I setted in reach view the protocolls of rover and base to NMEA too.
