Combination Model for UTC-UTC (NTSC) Time Offset Long-Term Prediction and Precision Evaluation

Abstract:

Coordinated Universal Time (UTC) is regarded as reference time scale for the worldwide time coordination. In order to steer master clock in timekeeping laboratory, it is necessary to make a prediction of UTC-UTC(Lab) time offset for 15~45 days. The prediction is based on two considerations, data size and prediction model. Compared with quadratic polynomial model and grey model, calculating results show a combination model based on 9 months data size is fitter to secular predicting in terms of both stability and accuracy.
