Design and realization of BDS attitude determination system
In order to realize the remote real-time processing of Beidou observation data online and solve the baseline attitude,this paper designs an attitude determination system based on Beidou observation,inclu-ding a data collecting terminal unit and an attitude determination solving scheme.The system uses the STM32 microcontroller as the control core,collects the observation data of Beidou system through GNSS board and antennas,and uploads the data to the server through 4G module.The observation data is ana-lyzed on the server and the real-time calculation is performed to achieve attitude determination.The attitude determination experiment verification of attitude determination work is carried out using the measured data of about 5km and about 100m baseline station,as well as the actual 2.6m baseline observation data collected by the attitude determination system described in this paper.The results show that for the three length base-lines,the Standard Deviation(STD)of azimuth and pitch angle is 0.0004° and 0.0003°,0.0014° and 0.0013°,and 0.0540° and 0.0891°,respectively,which can provide a reference for the application of Beidou system attitude determination.
