摘要
根据双频载波相位求差法推导了载波相位观测误差的概率统计模型,并用实例验证了运用该模型探测与修复周跳的有效性、准确性,证明该方法可以减小确定周跳的计算量,加快周跳探测与修复速度,并可对数据进行实时处理,可靠性强。
A carrier-phase error model on the base of probability and statistics was proposed according to the differenced data of the dual frequency carrier phase. The results of examples calculated with the model show that calculation amount of determining the cycle slip is reduced greatly and the speed detection and repair of cycle slip is improved significantly. Moreover, data can be processed timely and the result is reliable
