Satellite Clock Bias Prediction Based on Modified Single Difference Data of Clock Bias
Abstract An improved strategy for the prediction principle based on single difference values of satellite clock bias (SCB) is proposed. This paper analyzes prediction characteristics of the frequently-used linear polynomial model, quadratic polynomial model and grey model when they use the proposed prediction principle. The simulation results show that the proposed improvement for the prediction principle is effective and the prediction precision of the frequently-used models can get better prediction results based on the proposed prediction principle in the short-term SCB prediction.
