摘要
给出了一种快速GPS模糊度分解算法的改进方法 ,该算法通过白化处理 ,消除或减弱短时间内GPS载波双差观测量的相关性 ,提高了卡尔曼滤波器对模糊度估计精度 ,仿真结果表明 :对于短基线情况去相关处理可以在较短的时间内获得较小的估计偏差。
In this paper,a way of improving the fast GPS ambiguity resolution is presented This algorithm improves the precision of ambiguity's Kalman filter estimations through whitening process to remove or reduce the correlation of double-difference GPS carrier phase observations for short periods The simulating results show that smaller deviation can be obtained by decorrelation for short baselines over short observation periods
