摘要
周跳的探测和修复是实现高精度GPS测量的关键问题。目前对载波相位观测值周跳的探测和修复已有多种方法,但都有各自的不足。文中综合利用多项式拟合法和双频电离层残差法来探测和修复周跳。介绍两种方法的数学模型,给出具体实施步骤,利用算例验证方法的可靠性和有效性。
The cycle slip detection and reparation are the key to realize GPS measuring in high precision. At present, there have been lots of ways to detect and repair the carrier phase of observations, but each of which has its own inefficiency. It presents the mathematical model of the two methods to detect and repair the cycle slips by using polynomial fitting and ionosphere residual method, and provides the implementation steps. Finially, some experiments are made to analyze and test whether it is reliable and efficient.
