摘要
扼要介绍了北斗系统导航定位报告体制与工程技术;首先论述双星、三星、多星定位报告原理;然后概括北斗系统导航定位报告体制在性价比、位置报告、双业务融合、抗干扰方面的优势;最后分析出站下行、入站上行波束设计,信号频率及调制方式设计,双向距离和观测量分解与校正,自主导航载荷与定位报告链路融合设计,双向距离和观测量平滑与位置解算滤波等工程关键技术的解决途径。
This paper provides an overview of the BDS radio determination satellite system and engineering technology.Firstly,the principle of radio determination double-satellite,triple-satellite and multi-satellite is briefly described.Secondly,its advantages on cost performance,location reporting,double-businesses fusion and anti-interference are derived.Lastly,its key engineering technologies,that is,outstation beam and instation beam designing,signal frequency and modulation mode designing,sum of two-way distance observation decomposing and correcting,autonomous navigation payload and locating report link fusing,sum of two-way distance observation smoothing and position solution filtering,are analyzed.
