摘要
利用仿真实验研究BDS和GPS双星座中不同轨道卫星的组合导航精度和稳定性,选取全球不同经纬度代表区域进行实验。结果表明,在高纬度区域能够提高定位稳定性,中低纬度区域能够提高定位精度。研究成果对BDS的精度验证和多星座数据选取具有一定的参考意义。
By using the simulation experiment, the navigation precision and stability of different orbiting satellites in the double constellation of BeiDou system and GPS system at present are studied. Experiments were carried out on different regions of latitude and longitude in the world. The results showed that the stability of location was improved in high latitudes. At this stage the design have been reflected in the low latitude region to improve positioning accuracy. The research results have certain reference significance for the precision verification and multi-constellation data selection of BeiDou system.
