摘要
从全球定位及位置报告方案出发,提出基于卫星无线定位(RDSS)原理的快速三星高精度定位及位置报告原理、工程方案设计,分析了实时性、精度等主要指标,展现了该原理在全球快速救援以及动态用户跟踪的应用前景。采用Ru=RiS-RiSu矢量方程,完整表达了广义RDSS定位及位置报告原理,包含了以用户为测量及定位中心和用户外已知点为测量及定位中心的两种情况,将两种定位方式结合,就完成了位置报告。广义RDSS差分定位概念,将只具有单向伪距观测量的RNSS卫星纳入三星定位方程,实现了和GPS等卫星的兼容应用。为此,介绍了构成上述原理的CRDSS卫星的要求。
Based on global precise positioning and reporting, theory and proposal of comprehensive RDSS is introduced in this paper. Real time and accuracy of RDSS is analyzed. Foreground of application is forecasted. The formula of ^→Ru=^→RS^i-^→RSu^i is used to express the whole theory of comprehensive RDSS（CRDSS） position and report, which includes two cases, one takes the user as the center of measuring and positioning, the other takes the known points except the user as the center. The position report is the combination result of the above cases. The concept of CRDSS differential position realizes the complex applications of GPS satellites, by introducing the single way RNSS satellite to three satellite position formula. The requirements of CRDSS satellites are also provided.
