BDS/Galileo相位组合观测值优化选取

Optimal selection of BDS/Galileo phase combination observations

针对载波相位测量中,整周模糊度的快速正确求解受限于载波波长和测量噪声的问题,提出一种在保持模糊度为整数的前提下,利用BDS/Galileo载波相位虚拟组合观测值来增加波长并保持低测量噪声的方法,使之有利于模糊度的求解;根据组合观测值选取标准,对组合系数进行选取并获得几组有效观测值组合。结果表明,通过该方法能够获得满足特定性能的组合观测值。

Fast and correct integer ambiguity solution is limited by the wavelength and measurement noise in carrier phase measurement.Discussing on the issues,the paper came up with the idea that uses visual carrier phase combination observation of BDS/Galileo to increase the wavelength and keep low measurement nose.Under this condition,the ambiguity would be easily to be calculated.The principle of this method was elaborated in this paper.According to the selection criteria,the combination coefficient was selected and a few effective combination observations were got finally.The results showed that a few combination observations with specific properties could be obtained by using this method.
