| Abstract: | 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. |
