??Multiple pixhawks communicating to single Ground Control Station??

Posted by YTIEB on February 11, 2017 at 5:29pm

I am looking to have 3+ (ideally quite a few more) pixhawks send their live telemetry data to ideally one laptop that records this data as it comes in. Is this possible?

At the moment I am thinking either mission planner or Qgroundcontrol and using one of the swarm type modes. But Can these 'planners' deal with receiving lots of incoming communication?

Ideally I would like to use a method of long range communication like LoRa to send the data but I am unsure of how to get many of these at 433Mhz transceivers to talk to the GCS at the same time.

Any suggestions on hardware/software or threads that may help me out?

Thanks in advance!!

    Chris, thank you very much! Understood.

    Would this set-up allow me to record 4 live telemetry data streams with no interference? Or would I have to select a COM in turn to get each one of the four sets of data in turn? (I am not that familiar with QGroundControl!)

    Also - I imagine this set-up limits me to as many USB slots I can have?
    Is there a way of using Adaptive time division multiplexing or something else with one aerial?

    Also, do you think 'meshing' with xbees could be an option? Maybe using something like this: http://www.thanksbuyer.com/xbee-pro-900hp-s3b-module-with-adapter-m...
    Or would that still need multiple receivers?

    Thanks in advance!
