AB: GPS quality control is to determinate the quality of observations in terms of various error factors such as atmospheric effect, multipath, etc. It could be used to predict the accuracy of positions in field surveys. Because errors in observations deteriorate the accuracy of positioning, it is an important process to predict how much errors are contained in observations and determine if the accuracy goal of the survey is achievable. In this study, we present the standards of quality control based on theories and various simulation tests. The simulated data are constructed from GPSSIM module of Bernese GPS software Version 5.0. We created simulated data with various levels of error factors in two baselines lengths of 80km and 30km. Then, the simulated data are processed by TGO ver1.5, LGO ver2.0, and GPSurvey ver2.35. Through this procedure, we determine the relations between the quality of the observations in terms of each error sources and achievable positioning accuracy. It is expected that this study increase the efficiency of the general field survey by predicting the positional accuracies before the post processing.
