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

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!!

In QGroundControl you can have multi MAVs. Just use a USB hub and plug each one one of your radios into that. Each will get their own COM port and you can just assign each to a different MAV number. 


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!

I'm afraid I don't know anything about Xbees. As for recording all the datalogs, yes as I recall QGroundControl logs all the incoming MAVLink from all the MAVs, regardless of which one is currently being controlled

Brilliant thank you so much :)

You can also use UgCS to control multiple drones and store telemetry logs. Also UgCS can work with XBee modems, please see this document - https://www.ugcs.com/files/PDFs/Manuals/v2.9/manual-xbee.pdf.

Please let us know how you get on with this. I've been wanting to do some swarming experiments with our Wing GCS, but have not found the time yet.

My earlier investigations led me in the direction of QGround Control or UgCS as indicated above, or possibly APM Planner.

I am also looking to control multiple drones at the same time. Can I achieve this with my existing 3DR telemetry radios or do I need the XBee modem for sure? Also, can you please share a document which explains how to achieve multiple drone control with Q Ground Control (I am more familiar with Mission Planner)?

Yes, see my pictures in this thread that show how to use a USB hub to control multiple drones with 3DR radios. 

@Chris Anderson

Yes. I got that. How do I send commands to the drones so that they move together, get a formation, etc?

Oh. Just read the manual

Thanks. But I already saw this. Does it work properly with Mission Planner? Is Q Ground Control a better option?

Do I have to use similar drones or can I use drones of different sizes/frame types?
