I am using the new 3DR Ublox GPS with the big antenna. It gets a lock very fast and appears to be doing the right thing. However, I am having a weird problem whereby the pitch of the plane oscillates a few degress in mission planner when it is sitting still on a desk after the GPS gets a 3D lock. It is noticable in the mission planner HUD.
When I replace the GPS with my old MTK one, it works fine and no oscillation is observed.
I am using a new APM2.5 with arduplane 2.5.
Has anyone else experienced this problem? Any solutions out there?
I just received the new 2.5 and have just been doing a series of bench testing but with the MTK. I will put this in my quad tonight and it will be using the new UBlox gps so I will let you know what I find.
Thanks Jack. I would be intersted in your findings. There is another thread reporting this behavour with APM2.0, so it may be an issue with the GPS, not APM itself.
