摘要
通过GPS三频组合观测值周跳检验量,提出了利用最小二乘原则选择最优组合观测模型的方法,选择了一组最优组合模型。通过各载波间的频率关系,模拟出L5频数据,编制了周跳探测软件,通过实例验算,结果表明组合模型探测周跳精度优于其他模型。
With the test of cycle slips which come from the Tri-band combination of the GPS observation,we propose a method that can select the optimal combination of observation model using the Least-squares principle.With this method we choose an optimal combination model that is(0 1-1)(-3 1 3)(-7 9 0).Through the relationship between the carrier frequencies,we simulate the L5 carrier data.Preparation of a cycle slip detection software.And with the instance checking,we find out this combination model has more accurate than other models on cycle slip detection.
