In order to solve the problem of controlling ability of projectile’s attitude, the system of geomagnetic gyro combination pose measurement based on DSP is studied. Use the prototype of tri-axial MEMS gyro and geomagnetic, based on rotation vector attitude algorithms and TMS320F28335 for data processing, calculating the roll angle under different rotational speed and analyzing error. Test results show that the scheme can process gyro and magnetic signals and calculate attitude results in real-time, accurately and stably, meet the requirements of attitude control.
