Hi, I am using marvelmind with pixhawk… I got fixed GPS but with error : Unhealthy GPS Signal and AHRS not healthy … any help, please

Hdop should be below 1.0 yours is 1.2. If hdop below 0.8 would be better. Try to fly in clear sky area.

marvelmind is used for indoor navigation. it take x y z coordinates using stationary and converts them into gps coordinates. he is not flying outside.
