Error Statistics from Predicting UTI-UTC and Pole Position.

Abstract

Various equations and fit procedures were tested to determine an adequate procedure for predicting variations in the earth's rotational orientation and pole position over time periods of 5 to 20 days for application to the NAVSTAR Global Positioning System (GPS). It was shown that a 10-parameter fit to data observed over a one-year period would give 0.002 to 0.007 sec of time accuracy in the prediction of the earth's rotational orientation. A five-parameter fit to the X component of pole position and a seven-parameter fit to the Y component gave prediction accuracies of 0.005 to 0.012 sec of arc. (Author)
