Abstract

Gray system model is used in secular predicting GPS Cs clock error and Rb clock error, compared with quadratic polynomial model.Calculating results show that in the secular term (210 days)predicting GPS Cs clock error precision of gray system model is up to ns, and GPS Rb clock error precision of gray system model is up to 10ns, which exceeds quadratic polynomial model obviously and satisfies precision requirements in the real application.
