摘要
进入21世纪以来,GPS观测技术得到了迅猛发展和完善,在卫星导航、基础测绘、变形监测等方面已被广泛应用。而如何精确地确定GPS卫星轨道问题(即GPS卫星星历)是GPS观测技术中的一个重要内容。结合实际观测数据用广播星历和精密星历分别进行基线解算,通过对解算结果比较得到使用广播星历的最佳基线长度范围。
GPS observation techniques have developed rapidly since the 21st century. It is widely used in basic surveying and mapping, satellite navigation and deformation monitoring. How to determine the GPS orbit problem accurately is an im- portant content in GPS observation technology.The paper discusses the baseline solution with broadcast ephemeris and precise ephemeris, and obtains optimal length range of broadcast ephemeris by comparing the result of calculation.
