摘　　要：载体姿态测量的实际需要和多天线姿态测量的局限性决定了单天线姿态测量系统拥有广泛的发展前景。分析了单天线测姿的应用价值和基本原理,从我国的具体国情出发,提出了基于北斗卫星星座仿真的单天线姿态确定技术研究的方法。利用STK平台对目前组网运行的北斗卫星星座和理想的北斗满卫星星座进行了仿真,利用Matlab平台进行了实验,仿真实验结果和误差分析表明,北斗卫星星座仿真的单天线姿态确定技术在适用条件和测姿准确性等方面效果理想,在一定精度要求下满足应用需要,对建立实用可靠的单天线测姿具有积极的推动作用。To overcome the actual needs of the attitude measurement and the limitations of multi- antenna attitude measurement, the principle and the application value of the single- antenna attitude measurement was analyzed. Two models of Beidou constellation （ now and future） were simulated on STK, and the cor- responding data was introduced in Matlab for attitude identification. The simulation results and the error analysis showed that the single- antenna attitude determination technology based on the Beidou constella- tion was satisfied under certain accuracy requirements, which has positive value for the practical applica- tion of the single- antenna attitude measurement.
