In microwave communication, the conventional theodolite method for antenna azimuthcalibration is of large error and poor efficiency.
在微波通信中,天线方位角的校准通常采用经纬仪法,存在误差大、效率低的缺点。

In the software design the gyro's drift measure and the process of calibration is added. The Kalman filtering technique is used in the horizontal initial alignment and the azimuth initial alignment.
