Just got an APM 2.5, but unfortunately without the DF-13 to XBee connector that was supposed to come with all APM2.5's. While assembling the board, I noticed that the new DF-13 port is marked as…Continue

Hi, 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…Continue

Mapping with Ardupilot

Posted on November 1, 2011 at 1:45am 57 Comments

I've been playing with ArduPlane for quite a while and have finally got to the point where I can make it do something useful. I've been inspired by others on this site to use it for aerial photography to make 3D maps and the like.

 

I have an ST Models Discovery as the airframe (awesome platform for Arduplane by the way) and have made my own camera mount out of plywood for the bottom. It has one servo for roll stabilisation using CHAN 8 on the autopilot to keep the camera…
