摘要
针对参考站单站静态双频的特点,提出了一种综合利用双频载波相位观测值求差法和载波相位变化率来探测周跳并修复的新方法;介绍了两种方法的数学模型,给出了具体实施步骤;最后用算例验证了方法的可靠性和有效性。
A comprehensive method for detecting and repairing cycle slips is proposed with single and static station in dual frequency receiver. Dual frequency differenced carrier-phase and rate of carrier-phase change are utilized in this method. The mathematical model of two methods are introduced in this paper, and then the concrete implementation steps are presented. The reliability and validity of the method are testified by an example.
