Using IMU, GPS and controlled by PID, it finally drifted less and can hover!!All channels are automatic, except the throttle is controlled manually, so it's still a 'semi' auto hover. Will definitely move to fully automatic soon!Video1Video2Hurray!!!
You need to be a member of diydrones to add comments!
nick, Jack, what microcontroller (or mini computer) are you using to handle all the sensors and control loops? I looked around a bit and didnt see it mentioned elsewhere.
Most of the commercial autopilots don't need DGPS anymore. There should be no drift with the Novatel DGPS. It's probably an error in sending correction sentences from base station to aircraft. Your main concern is climb rate.
Thanks! Yeah it's manual throttle control. And will use the height reading from GPS for altitude control.
The quality of height reading wasn't good, jumps up and down up to +/-10 meters occasionally, so I will probably filter the altitude with a really low cut-off frequency then feed it to control loop.

Any suggestion??
