Method for forecasting receiver clock error

TL;DR: In this article, a WMAD-based GNSS satellite clock error data preprocessing method is proposed to solve the problem that a classical gross error detection method cannot effectively eliminate errors with smaller magnitude in clock errors.

TL;DR: In this paper, a novel GNSS (Global Navigation Satellite System) ultra-fast clock error forecasting method was proposed, which improved the current situation that the existing GNSS clock error forecast method is lower in clock error real-time forecasting precision and poorer in stability, and comprises the following steps of: preprocessing clock error data; performing principal component analysis on the clock errors; respectively carrying out modeling prediction on the main components and the total residual error sequence; obtaining a final forecast value.

TL;DR: In this paper, a frame network displacement prediction method based on a combined model was proposed, which has the advantages of being high in prediction accuracy, wide in applied range and the like.

TL;DR: In this paper, a method for estimating the clock deviation of a satellite navigation timing receiver is presented, which includes the steps of polynomial fitting, model simplification and matrix solution.

TL;DR: In this article, a judge module, an information storage module and an information processing module are added in the system, which can solve the navigation and position problem in signal blind areas within a small range, and only a certain correction is required based on the existing basis of GPS navigation equipment without big cost change and volume change.

TL;DR: In this article, a method for converting an original measurement value of a global positioning system (GPS) into a precise and uniform sampling was proposed, which relates to the global positioning technology.
