I changed the OS to Ubuntu 16.04 for the Intel Aero RTF Drone. When I fly the drone indoors, the GPS will not work well, the drone can not know the exact position. But we have VICON system in the room. How should I sent the position data detected by VICON system to the drone in real time so in this way we can tell the drone the real position is? By doing this the drone will not use the position data from GPS, and will use the position data received from the VICON system. Is Mocap node the right thing to do? Also Do I need to connect the QGroundControl software every time I fly the drone? It would be great if I can get some reference.
