摘要: 设计了一套实时数据质量控制模块,利用观测值的多种线性组合进行周跳探测及修复,并对观测方程的验后残差进行实时分析,来探测粗差和周跳,从而使实时数据的处理结果更加稳定可靠,并在PANDA单历元实时数据处理模块(SRIF)的基础上,运用实时质量控制模块进行试验。结果表明,此模块更加稳定可靠,适用于GNSS实时数据处理。

Abstract: 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.
