yesterday I finally had the time to try my new ublox gps. I fly in a zone with a very bad satellite reception (high mountains all around).
What I verified with the ublox vs em406 is that in two flight the plane made 2x each flight 9WP sequence with various altitudes at each waypoint. I was impressed by the precision of the altitude hold.
With the em406 the plane had some difficult to reach the wp an sometimes it missed them at first attempt, say 1 on 3-4 (the plane will then turn around until it reach the radius, 30m in my case).
Yesterday, with the ublox, it missed a wp only two time. I consider 2 wp missed at first attempt on 36 a very satisfactory result.
1hz refresh means 20m error befor it react vs 5m of 4hz refresh.
I consider this a great improvement on this beautiful equipement: very happy to have it (and the great support too).
To be honest I have to say that the plane dives two times; one time it recover itself and continued the sequence, the second I had to recover it manually.
Bad satellite connection?
Bad IR readings?
Both?
*??
Next step I would integrate it with remzibi osd to be able to take videos (so sorry a day has only 24h >;-D).
Wish list:
- speed hold
- be able to set a fixed rtl altitude

The Ublox update rate is 5 Hz vs 1 Hz for the EM406A.
