Did u check the GPS_SOL in messages, Pacc(position accuracy), Sacc(speed accuracy), Pdop, numSV (number of satellite detected.) and SVINFO, which tells the information about satellite.

If Pacc is bigger than 10 meters, gcs will sound a alarm automatically. GPS will need at least 4 satellites to get a good GPS 3-d lock.

I'm having problem with tiny 2.1 + lea-5h

I get message Invalid argument "latlong.of_utm"  after it boot up.
In GCS it says my aircraft is at approximate 0.0000 172.323432
no mater where the plane move to , it will not track in gcs.

Get 3d lock.
When I load up gps tunnel to check the GPS with u centre, the location report correct position.

Any suggestion?

Your sincerely
