7 . based on the comparison with dual band gps phase and c / acode , ambiguity function method , least squares search , ambiguity solution covariance , cholesky disintegrate and least square ambiguity decorrelation adjustment , it is considered the method of ambiguity function using double gps antennas to move baseline and the equation of dual differential carrier phase
在分析双频p码伪距法、模糊度函数法、最小二乘搜索法、模糊度协方差法、 cholesky分解法、和lambda算法的基础上，重点研究基于双gps天线动一动基线载波相位双差整周模糊度确定方法。
