GPS L1,L2双拼周跳探测与修复，包含几种常用的实时探测算法，附有GUI界面(A MATLAB software package for GPS cycle-slip processing is presented in this paper. It realizes cycle-slip detection and repair in the measurement domain for GPS L1 and L2 signals. The software implements several classic approaches oriented to real-time processing. With the graphic user interface, the user can configure the raw data, set algorithm-related parameters, add synthetic cycle-slips, and view the detection results in both text and illustrated forms. )
