摘要
根据GPS和BDS组合系统中基线解算的基本理论,从时间基准、空间基准、坐标系统、卫星位置四个方面,将BDS的观测数据归算到GPS基准下,与GPS观测数据统一进行计算,论证了GPS/BDS系统组合定位的优势。最后通过工程实践,验证了组合定位在工程测量中的应用情况。
According to the basic theory of baseline solution in GPS and BDS combined system,the observation data of BDS is calculated into the GPS benchmark from the four aspects of time reference,spatial reference,coordinate system and satellite position,and the GPS observation data is calculated uniformly.This paper describes the advantages of GPS/BDS system combination positioning.Finally,the application of combined positioning in engineering measurement is verified through engineering practice.
