Cheng Mengfei - Analysis on Prediction Characteristics of time offsets in GNSS - October 29, 2018 • 397 Views
To realize compatible interoperability in global navigation satellite system(GNSS), a unified time system need to be established. Monitoring and predicting time offsets between different navigation satellite systems can help unify the times. Taking UTC(Coordinated Universal Time) for reference, this paper contrasts and analyses predicting performance of times in different GNSS, then predicts the time offsets by polynomial model, gray model, Kalman model, and AR model, and their predicting accuracy and characteristics are studied and discussed. At last, some new conclusions are got in experiments.
