摘　　要：高精度GPS定位中,数据预处理的好坏直接决定其定位精度和可靠性,而其中的关键之一就是要准确可靠地探测出观测值中出现的周跳。在进行GPS周跳探测时,如何根据观测值的变化规律、不同的观测数据类型及其组合、观测历元间估值残差等来采取不同的周跳探测方法。同时提出各种方法的特点及适用范围。In the high-precision GPS positioning, data preprocessing directly determines the positioning accuracy and reliability, one of the keys of which is to accurately and reliably detect the cycle-slip which appears in the observations. This article will elaborate when making cycle-slip detection, How to adopt different method of cycle-slip detection according to the rule of the observation data, the different observation data types and combinations, the observation residuals valuations between epochs and so on. Simultaneously proposes each method characteristic and the applicable scope.
