Abstract

Predictions of the time-offset of individual GPS satellites from the IGS rapid timescale are computed with significantly lower prediction uncertainties than may currently be obtained using the IGS ultra-rapid predictions. The factors contributing to the uncertainties in the IGS predictions are discussed. The application of a Kalman filter based prediction algorithm is shown to produce close to optimal predictions
