| 摘 要： | 提出了一种基于卫星导航 RNSS ／RDSS 组合业务的三星定位算法，该算法是通过用户同时观测3个 RNSS 业务和1个 RDSS 业务伪距观测量，建立用户伪距观测方程组，再采用最小二乘法求解用户三维位置坐标和钟差，实现基于 RNSS ／RDSS 组合业务伪距观测量的三星快速定位；通过理论推导，分析了伪距观测误差对用户定位精度影响。通过数据仿真试验，验证了实际三星定位组合星座和伪距观测噪声条件下的用户定位精度。

Tri-Satellite Quick Positioning Algorithm Based on Generalized RNSS/RDSS System |

| Abstract: | The paper put forward a tri-satellite quick positioning algorithm of generalized RNSS /RDSS system.According to the characteristics of generalized RNSS /RDSS system based on integrated RNSS and RDSS service,the algorithm accomplished user’s tri-satellite quick positioning calculation adopting least squares techniques,through acquiring 3 RNSS and 1 RDSS pseudo-range observation quantity and correcting pseudo-ranges.The influence of pseudo-range measuring error toward accuracy of positioning was analyzed in theory.The accuracy of positioning was proved by experiment,under tri-satellite constellation and measuring noise conditions of compass at present,using emulation and observation data of RNSS +RDSS pseudo-range. |
