摘　　要：基于北斗导航系统的高精度定位技术已应用于航标遥测遥控、技术测量等作业场合。但在某些航标作业应用中,高精度定位设备天线无法固定在作业点上(例如海上航标抛设作业),此时原定位模式便不能满足应用要求。针对上述问题,提出采用主辅天线模式,静态获取参数,动态解算作业点经纬度的方案,并抽象出数学模型,设计了完整的算法,通过实测数据验证了算法的可行性。The high-precision positioning technology based on the Beidou Navigation System has been applied to the remote control and monitoring of marine aids to navigation(Ato N), technical measurement, etc. However, in some applications of Ato N, the antenna of the high-precision positioning equipment cannot be fixed on the operation site(e.g. the throwing operation of marine Ato N), and the original positioning mode cannot meet the application requirements in such cases. In view of the above problems, this paper proposes a scheme of adopting the main and auxiliary antenna mode, statically obtaining parameters, and dynamically calculating the latitude and longitude of the operation site, and abstracts the mathematical model, designs a complete algorithm, and verifies the feasibility of the algorithm through the data from actual measurement.
