本文针对快速、高精度及高可靠度方位标定的需求,采用北斗卫星载波相位差分技术实现方位角测量。首先介绍了基于北斗卫星定向的原理和算法流程,重点研究了周跳检测及修复和整周模糊度估计等定向核心技术,开展了短基线试验验证,结果表明,方位角精度满足高精度方位标定的应用需求。

For the requirements of high-speed,high precision and high-reliability azimuth calibration,we adopt the technology of BDS satellite carrier phase difference to achieve azimuth measurement.Firstly,the principle and algorithm process based on BDS satellite orientation are introduced;Secondly,the core technologies such as cycle-slip detection and ambiguity estimation are emphatically studied;Finally,we carry out the verification in short base-line,the results show that the azimuth accuracy meets the requirements of azimuth calibration.
