Today I did my first flight to test a new Pixhawk 2.1 with Here antenna (original ProfiCNC/Hex product).
PX4 flight stack, FC mounted on a hexa which flew amazingly with the Pixhawk 1 and M8N GNSS.
Omitting that flight reactions are tweaky, my concern is that flying with Position Flight Mode, the bird doesn't keep its position as expected.
14 satellites liked, 0.3 HDOP, but the drone doesn't keep its position as the Pixhawk 1 with APM and M8N used to keep like a pole.
The Pixhawk 2.1 with Here antenna allows to move the drone of a few meters and I must control it manually almost like flying in Stabilize mode.
Why it doesn't stuck on its stable GPS position?
Thanks to all those of you that will help me solving this issue.
