Estimating stability and reliability of satellite clock jump

As one of the main broadcast information in the navigation message, satellite clock errors are directly related with users' positioning accuracy. Given the current indicators of the "Bei Dou" on-board atomic clock's stability, this paper, based on the user testing angle, tests and estimates satellite clock parameters' consistency and smoothness of the "Bei Dou" navigation message by designing a consistency test method of the satellite clock errors correction forecast model and prediction accuracy, ensuring that users can reliably make good use of high-quality data. © 2012 Springer-Verlag.
