摘要/Abstract

摘要： RDSS短报文是北斗卫星导航系统(以下简称北斗系统)的特色服务,实现了用户报文通信和位置报告。北斗系统早期的位置报告基于双星RDSS观测值,其精度受限于数字高程数据的精度。从BDS-2开始,北斗系统发展了融合RNSS和RDSS体制的位置报告方法,其基于北斗RDSS体制,将用户接收机的观测数据向中心站进行回传,并在中心站实现精密位置的解算和报告,提升了服务覆盖范围和定位精度。本文介绍了北斗精密定位报告系统采用的中心站处理算法,并采用分布于中国不同区域的50个北斗观测站数据对系统性能进行评估。分析了RDSS入站频度、用户站与监测站的基线长度等因素对用户定位的影响。结果表明,基于北斗分区综合改正数的精密单点定位的精度最优,其在2 min响应时间内的平面和高程精度(RMS)分别为0.51 m和0.94 m。北斗精密定位报告精度与基线长度相关性较小,在仅采用BDS-2数据的情况下,定位精度下降可达1倍以上,而在相同时长情况下,提高RDSS入站申请频度对定位性能不产生影响。

Abstract: RDSS (radio determination satellite service) short message is a characteristic service of the BeiDou satellite navigation system (BDS), which realizes user short-message communication and location reporting. The BDS RDSS based location reporting was realized for the first time on its first-generation system (BDS-1) using two GEO (geo-stationary earth orbit) satellites, and its accuracy was limited by the accuracy of the digital elevation model (DEM) database, which was used to assist its realization of 3D positioning service using two satellites only. Starting from its regional System (BDS-2), BDS has developed new technology of the location reporting in the Master Control Center (MCC) by integrating the RNSS (radio navigation satellite system) and RDSS observations. In the new development, the RNSS range and carrier phase observations of user stations are transmitted to the MCC through RDSS link, and the RNSS observations are used to determine users' precise positions in the MCC. Supported by the various types of precise spatio-temporal data, e.g. precise satellite orbits and clocks, the precision of user positioning is thus greatly improved. In this paper, we introduce the three location reporting processing algorithms used in the MCC central station, and evaluates their performance with respect to the sampling rates and baseline length. Data of the 50 BDS tracking stations in Mainland China is used to validate the performance. Results show that the precision of the location reporting realized in the MCC reaches 0.51 m and 0.94 m for horizontal and height components, respectively. The positioning precision shows little relation to both the baseline length and sampling rates, while the precision of BDS-2+BDS-3 combined solutions is improved by around 50% over the solutions using BDS-2 observations only.

Key words: BeiDou satellite navigation system, precise positioning, RDSS location reporting, zone correction
