GPS变形监测中整周模糊度解算的新方法

A New Method for Integer Ambiguity Resolution in GPS Deformation Monitoring

利用变形监测网中监测点坐标已知的特点,提出了一种新的解算整周模糊度的方法———DC(directcalculation)算法。该方法不需要组成和解算法方程,更不需要搜索和确认,而是直接计算整周模糊度。实际计算表明,该方法计算速度快,精度高,是变形监测中整周模糊度解算的极好方法。

In the case that the accurate coordinates of the monitoring point and reference station are known, a new method for integer ambiguity resolution--DC（direct calculation） is introduced. The results of tests indicate that the above algorithm can solve precisely and fast for the integer ambiguity. It is a good method for integer ambiguity resolution in GPS deformation monitoring.
