Hey thanks for replying... I'm using the older version of 3DR Ublox LEA-6H Module. I mean this module(see link) but without the compass,
Yes it shows my position correctly but the quad on the mission planner still has some deflection. Sometimes it shows home on the mission planner but the Blue LED of the GPS keep blinking. Yes My GPS has a clear view of the sky. But as I'm doing it in the roof top there are some other houses beside me. Can this be a problem?
How I could configure my GPS module? please tell. And is there any other GPS module better than the ublox to use with APM 2.5? please give me the link if any unit is available to work with APM. Here is the picture of my GPS module
