Compared with GPS data post processing,real-time GPS data are not reliable,and process of real-time data processing can't be reversed,so GPS real-time data quality control is particularly important.This paper designs a set of real-time data quality control module,it detects and corrects cycle-slip by using the combination of observations,then detects cycle-slip and gross errors by analyzing posteriori residual of observation equations,so real-time data processing is more stable and reliable.Based on single real-time data processing module(SRIF) in PANDA software,this paper tests real-time quality control module,and the results indicates that this module is more stable and reliable,and is suitable for GPS real-time data processing.
