Hi guys
I'm pretty new here, but not new to multicopters. I built my first MK over 5 years ago, recently put together a CarbonCore 500mm quad and recently built up my first hex, a Vulcan 900mm Pro witha the Naza-M.
I took it for its short maiden flight this evening and I'm very pleased.
I've now mounted up the GPS unit and I'll be setting that up tomorrow, but it raises a question I can't think of an answer to, namely:
If the IMU is in the main Naza unit, why would you ever need to tell the flight control system the offset of the GPS from the CofG? What possible difference would that make to the interpretation of the GPS or magnetometer readings?
IMU offset I totally get, as rotations induce linear accelerations due to offset from the roll centre, but GPS and compass headings, not so much.
Please explain
Thanks
Martyn
