This question is regarding a drone and its GPS/Barometer sensor and may not fit well in this community and if that's the case, please advise if I should move it elsewhere.
So. I have built a DJI F550 Hexacopter along with a:
- Naza M V2 + GPS
- H3-3D and GoPro
- DJI mini iOSD
- Boscam 600mw VTX
- Skyzone goggles
- Futaba 8FGH RX
I live in New Zealand and the ski season starts in the next few weeks. My plan is to take the drone to the ski slopes and do some FPV flying following my mates downslope and in the park with hopes to get some nice footage.
I have a few concerns about it, such as how elevation will play flying in GPS/Atti mode.
Atti mode uses a barometer to maintain altitude and GPS mode uses, well, GPS. In ATTI mode, does anyone know whether the barometer will be accurate enough to keep the quad at more or less the right altitude and aid me in my flight? If the sensor has inaccurate readings, the drone will likely jump up and down erratically.
Likewise, would GPS be reliable on a downward slope and constant changes in elevation? I have used a ski tracker on my iPhone before which used GPS and it seemed pretty accurate but I'm unsure what precisions these GPS units have on mountain slopes.
Anyone with experience or knowledge in this field that can help out would be greatly appreciated.
