I am trying to get redundant ground control stations working. I have been reading through Link Management — MAVProxy documentation and Modules — MAVProxy documentation and I am not sure how to use link management.
What I’m looking to achieve is to have 2 computers, each with their own RFD900X connected to it. The vehicle will transmit to both of them, but only receive commands from the first computer.
If the first computer/radio has any sort of failure, the second computer/radio would be activated to take control of the flight.
I have been able to get both radios working from the same computer, but that is not what I want to do. I want 2 separate instances of Mission Planner on 2 separate computers.
Thank you,
Anyone know a solution for this?
That should work by default though secondary GCS will be able to send commands at any time (as it should). The only consideration is not sending RC overrides from secondary GCS if primary GCS is used as RC (using RC override).
The primary GCS and secondary GCS both are using RC passthrough.
I have an frsky rs mini connected to a RFD900X on each GCS.
I have been able to connect to them with the 2 separate computers but it was unusably slow. Im not sure if that was a symptom of passing through RC commands or not
Is there a way to disable RC commands from GCS #2 until I need it?
No. Ardupilot doesn’t really support multiple RCIN streams. You could connect the secondary RC handset to the secondary GCS and use Mission Planner joystick support to provide fallback RC. Though then you should enable low latency mode in RFD so it looks for RC override packets and sends them immediately instead of keeping them in FIFO.
I was originally going to use the same RC handset for both of the ground control stations, but that doesn’t seem to solve or create any problems if ardupilot wont handle 2x RCIN streams.
Then it seems like I also wouldn’t be able to simply have a second controller set due to still sending multiple RCIN streams.
Do you know if the RFD900X just sends a constant RC stream/heartbeat since I have it set up for SBUS passthrough? I’m wondering if I could simply not turn on the second controller until needed.
Being that there is only 1 radio onboard, and there is only 1 RCIN onboard, perhaps there is a solution through the radios that only sends 1x RCIN stream? The passthrough is entirely enabled through the RFD900X and I don’t have to tune any parameters in mission planner to get it to work correctly.
Having three radios in point to point mode on one network isn’t supported and IIRC SBUS/PPM isn’t supported in mesh modes.
Do you have any ideas what I can do to have a redundant GCS setup?
Not with your apparent requirements.
