"I also don't know if this helps, but here are the compass offsets from the mission planner.


COMPASS_OFS_X

-400 400
Offset to be added to the compass x-axis values to compensate for metal in the frame

"quick edit, the first screenshot was where I held the device parallel to the ground, the second screenshot was when I oriented it to try to maximize the z axis but ended up with a magnetic magnitude vector of almost 0."

Hey everyone. I bought the external compass/mag and I think the magnetometer is bad. (using apm 2.5, firmware v3.1.5 traditional heli and I've cut the line on the apm 2.5 to enable external compass). The Z axis on the magnetometer seems to be 'near…

Hey, does anyone know a simple algorithm for fusing GPS (position (and maybe velocity)) with INS (accelerometer) data? I say simple because the Extended Kalman filter articles I see all over the place are all to hard for my brain to comprehend. I've…

Robert S. replied to Robert S.'s discussion Can't change baud rate on Ublox GPS
"So after another two days of trying to change the baud rate, the baud rate still doesn't change. I have at least verified that I don't get an 'ack' back after trying to change the baud rate.

Does anyone have any c code examples that I could run a…"

Hey everyone, I ordered the APM 2.5 with the Ublox (Lea-6H) GPS module, and I am writing my own custom code (C++ using AVR Studio) to integrate with the hardware on the APM. So far, I have successfully integrated with the Barometer, IMU (gyro,…
