Abstract

The BeiDou-3 global satellite navigation system (BDS-3) provides two radio determination satellite service (RDSS) positioning services for users, i.e., the traditional RDSS (TRDSS) positioning of the BeiDou-2 regional satellite navigation system, and the comprehensive RDSS (CRDSS) positioning, which integrates the RDSS and radio navigation satellite service. As published studies regarding the RDSS positioning service are few, we analyze and compare the performances of the two RDSS positioning modes. First, we systematically investigate the principles of the TRDSS and CRDSS positioning, and then analyze the evaluation methods in terms of their positioning accuracy, real time, and coverage range. Second, based on the BeiDou RDSS measured data, we evaluate the performances of the TRDSS and CRDSS positioning. Compared with TRDSS positioning, CRDSS positioning exhibits the following: 1) A significant increase in positioning accuracy, resulting in error improvement from 8 to 2 m and root mean square improvement from 3.13 to 0.85 m; in other words, the positioning error, constant deviation, and stability improve significantly. 2) The real time reduces slightly from 1.1 to 1.8 ns, which is within the acceptable range. 3) The coverage range expands from the areas of 62°E–145°E and 5°N–55°N to the areas of 50°E–170°E and 0°N–70°N, respectively. 4) CRDSS positioning is not restricted by the constraints of the digital elevation database or the user elevation information and can thus solve the occlusion problem effectively.

北斗三号系统两种RDSS定位模式性能分析

北斗三号全球卫星导航系统(BDS-3)为用户提供两种无线电确定卫星业务(RDSS)定位服务，即北斗二号区域卫星导航系统的传统RDSS (TRDSS)定位和RDSS与无线电导航卫星业务相结合的综合RDSS (CRDSS)定位。由于目前关于RDSS定位服务的研究较少，本文对两种RDSS定位模式的性能进行了分析和比较。首先，系统研究了TRDSS和CRDSS定位原理，并从定位精度、实时性和覆盖范围三个方面分析了其评价方法。其次，基于北斗RDSS实测数据，对TRDSS和CRDSS定位性能进行了评价。与TRDSS定位相比，CRDSS定位具有以下特点:1)定位精度显著提高，定位误差从8 m提高到2 m，均方根从3.13 m提高到0.85 m;也就是说，定位误差、恒差和稳定性都有了明显的提高。2)实时性从1.1 ns略微降低到1.8 ns，在可接受范围内。3)覆盖范围分别从62°E - 145°E和5°N - 55°N扩大到50°E - 170°E和0°N - 70°N。4) CRDSS定位不受数字高程数据库或用户高程信息的约束，可以有效解决遮挡问题。
