Hi all,I must first express my happiness on finding this forum. This is a great UAV forum with lot of experience and i have gained a lot of knowledge by reading the discussions in the forum. Thank you all for sharing your knowledge.Its a few months since i have started learning about autopilots, and i desire to build a low cost one myself. When i see the commercially available autopilots i see that all the processing of the GPS, sensor data is done on the UAV itself. I was wondering if it is possible to transmit all the data to the ground station(computer) for processing and from the ground station send the pwm values back to the servos onboard the UAV to control the servos?What do you think are the cons (or pros) of this methodology? The main reason why i want to do this is, processing of data ( like working with floating numbers, trign functions, control loops) is easier done on the general purpose computer( ground station).

I think you'll find that wireless bandwidth, latency and range will be problems with standard wireless gear like Xbee. Jack Crossfire has done it with a heli, but even that one generated the PWM onboard.
