  • Hi,
    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

    Regards.

  • Can you use Ublox GPS with the UAV DevBoard? It only says it can work with ArduPilot board.
  • I will try to post some empirical data in the next couple of weeks, I have been experimenting with my EM406A and have not been impressed, When I saw the Ublox for sale over the weekend here I jumped on it! So I'm waiting on it to come in. Once I get it I'll try to run some tests using my netbook and an arduino.
  • Has anyone compared it to the Venus GPS? On paper that one sounds great (10Hz) and less of a pain to integrate. But I havent heard too many real experiences with it.
  • Does it get a better signal then the 406 when pitched at an angle?
  • 3D Robotics
    Actually, to be precise, the uBlox 5 delivers 4Hz in practice. But the accuracy is amazing, from altitude to sat aquisition, and it even works indoors!
  • 100KM
    From what i understand you can derive acceleration data from it . more here

    George,

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