Topic: My first flight GPS Flight Recorder and QGC
Today I was able to test my newly arrived GPS using both the Parrot App and QgroundControl discussed elsewhere here.
Firstly the GPS Flight Recorder was controlled by the latest Ipad, wireless only, the drone was flown without cover as I was using a 1500 battery which is higher than the standard and coupled with the GPS is a tight fit!
Location of the drone on Google Maps was nearly spot on, not military grade but close enough! set a single way point was no problem and the vehicle flew well in a slight breeze, it feels strange not piloting but following the track on the map as no visual from the camera that I could find from this method.
Hitting the home button resulted in an immediate course change to return, creating a new way point whilst flying is simple and you can manoeuvre the machine virtually anywhere you want within limits, I was on a soccer field and manoeuvred the drone from boundary to boundary and goal to goal without loosing control so can't tell what happens if the signal goes off.
The drone did seem to struggle getting hight with the extra weight of battery and GPS, at about 25% power remaining height was impossible, probably not the best of batteries.
I used version 1.0.4 of QGroundControl with a Lenovo T410 laptop windows OS, I had set up way-points the night before for the soccer field this laptop also has a built in 3/4G modem so it has mobile broadband as well as wireless.
The first thing I noticed was the drone GPS communicates with QGC but unlike the Parrot app position reported in QGC is no where near accurate as in Flight Recorder! this means accuracy with the way-points is suspect, the laptop also has it's own built in GPS and when I activated that found it to report correctly so the drone GPS is reporting a correct location, Flight Recorder is showing that but QGC is way off at least 5 meters!
I did get the drone in the air with QGC however it seemed to have it's own agenda as to where it was going, before flight I had confirmed that the way points in the GPS were as plotted in QGC, what happened next left me a little worried about QGC, the drone moved off about 10 meters no where near the first way-point and climbed to about 30 meters where it just hovered!
I had lost control! I request via QGC, a termination of mission, landing, emergency turn off all failed to produce any control over the drone, my last resort was to terminate the wifi which brought the drone into land in a controlled manner.
Clearly the drone could travel far and high without any control so need to get a better grip of QGC before I try that again, there are a few other PC controll programs I have found so will give them ago, QGC is attractive due to the ability to set way-points but not at the lost of aircraft, Flight Recorder does the job, seems to me Parrot could add the ability to add way-points to their program without much trouble
The flight testing was good, always a good day when no crashes are involved
