In order to enhance positioning accuracy and reliability,improve data utilization,improve the success rate of epoch result,a stratified weighting algorithm based on posterior residual error was designed for multi-GNSS.The algorithm can greatly improve reliability,accuracy and the success rate of epoch result without affecting positioning accuracy.Firstly,the GNSS date to be processed was solved based on weight allocated by priori information,then the system weight is allocated by posterior residual error of above results of each system,and this is the first layer weight allocation.
