Abstract

This paper presents a new algorithm for compensation of the time interval error (TIE), applying an unbiased p-step predictive FIR filter (with and without prediction) to the signal global positioning system (GPS) SynPaQ III with problems of holdover, using as reference a rubidium atomic clock. The TIE refers to errors resulting in system stability. The error holdover is a problem that at present does not possess solution and the systems that present this type of error produce lines of erroneous synchronization in the signal of the GPS. The results from this study show that it is possible to emulate an atomic clock using a GPS receiver.
