### How to get xyz position from 9DOF IMU output?

Started this discussion. Last reply by Luke Olson Oct 11, 2012.

Hello guys, I am doing a project which wants to control the helicopter by laptop so that the helicopter can follow the path we want. I got the 9DOF IMU from sparkfun and I can get the pitch, yaw,…Continue

### How to get xyz position from 9DOF IMU output?

Hello guys, I am doing a project which wants to control the helicopter by laptop so that the helicopter can follow the path we want. I got the 9DOF IMU from sparkfun and I can get the pitch, yaw, roll value from the IMU. I want to know how to convert these values to vector position, like in xyz axis. Thank you very much for your help. WangSee More
