摘要
针对北斗系统高精度动态差分定位解算不够快速准确等问题,该文介绍北斗导航卫星系统载波相位动态差分定位方法:利用B1、B2载波相位观测值组成双差宽巷载波相位观测值,进行双差宽巷组合观测值整周模糊度的确定,然后解算双差载波相位观测值的整周模糊度,利用载波相位观测值进行动态定位解算;并通过BDS实测数据进行算法验证,证明本文解算的方法可以实现BDS高精度差分定位的整周模糊度动态解算,得到测站的厘米级差分定位结果。
Aiming at the problem that the calculation of high-precise dynamic difference positioning is not rapid and accurate, the paper introduced the positioning method of BDS Navigation Satellite System： the double difference wide-lane carrier phase observations were formed by the carrier phase observations of frequencies B1 and B2, the integer ambiguities of double difference wide-lane carrier phase observations were fixed, and the integer ambiguities of double difference carrier phase observations were resolved, then the dynamic positioning was carried out by carrier phase observations. Finally, experimental result proved the feasibility of the method with its high precision.
