High precision positioning is based on carrier phase measurements . how to confirm integer ambiguity is very important 以载波相位观测量为依据进行高精度定位时,整周模糊度的确定是一个关键问题。
The two algorithms do not use information of relative attitude dynamics between spacecrafts . relative attitude is estimated by pseudo observation 通过建立联系编队卫星姿态关系的虚拟观测量求解相对姿态。
Recently , with the development of gps , many researchers pay attention to the real - time position for mobile users 近年来,随着gps的发展和完善,利用gps载波相位观测量进行移动用户的实时定位技术研究,开始受到人们的关注。
Integer ambiguity resolution is the key problem of gps based real - time attitude determination system which use double differencing carrier phase observables Gps姿态测量通常采用双差载波相位观测量,因此整周模糊值解算成为gps实时姿态测量的关键问题。
Also , vsop cannot frequently change observing object , hence it cannot supply more observations to many quasars , which are required for geodesy and geodynamics Vsop还不适合于频繁改变观测对象,所以无法提供针对多个射电源的观测量,而这正是大地测量和地球动力学所需要的。
In this dissertation , the theory and realiztion of gps based attitude determination technique are studied , multipath effects on gps observables and carrier phase multipath mitigation are also analyzed 本文研究了gps实时姿态测量技术的理论及实现,并分析了多径效应对gps观测量的影响及载波相位多径误差抑制。
