You are using the ocean server compass?

Are you using the depth sensor as well?

There is no calibration SW? or just no linux SW? Would you know if there is depth calibration SW?

I would guess that the elphel should just be able to parse NMEA-0183, then it can work with most compass modules (KVH, PNI TCM-2, etc.)

On IRC I heared there is no calibration on the compass. So probably it only gives lets say the rotation it makes like a gyro does.

FWIW, the compass does support hard-iron calibration via simple serial commands plus manual rotation of the compass. See ocean server compass manual. This is similar to other compass modules. It would seem that this is an application level procedure and not really suitable for embedding in the camera. It would be nice if the camera did allow for a redirect of the serial comms to a network socket or something.

Why not doing it from the camera ? It's what we did the first time we got the compass. We calibrate it via the serial port with some special commands. It is possible I think to build a PHP app that will launch compass calibration on request from the browser. So the user will only have to manually rotate the camera.
