The azimuth angles of platform and vehicle will be obtained by an integrator from azimuth rate signals measured by an azimuth gyroscope supported on a horizontal gimbal.

This paper presents the design and actual circuit of a computer control system for the North-Seeker with ARM7 (here LPC2292 is used) as core microprocessor and the flexible gyro as sensor.

By compensating the gyroscope's drifting with computer data processing, the precision of azimuth measurement was significantly improved.
