摘要
由于长基线变换矩阵中的窄巷组合难以单历元固定模糊度,提出采用数据平滑方法对其进行改进,并利用北斗实测数据对该方法进行验证,实验结果表明:历元平滑后的矩阵变换能够实现长基线多频模糊度的快速解算,从而提高了长基线精密导航定位的效率。
The matrix transformation algorithm for ambiguity resolution is transformation introduced,and the matrix changing algorithm for long baseline multi-frequency rapid ambiguity resolution has been principally analyzed.The narrow-lane combination ambiguity resolution in long baseline transformation matrix can not be realized in a single epoch,the data smoothing method has been used to solve this problem.Finally Beidou triple-frequency data have been used to validate the algorithm,the result indicates the matrix transformation algorithm can realize long baseline multi-frequency rapid ambiguity resolution,and enhance the efficiency of long baseline precise positioning and navigation.
