Description
Summary:In this paper we present a new algorithm of compensation of the time interval error (TIE) applying an unbiased p-step predictive finite impulse response (FIR) filter at the signal of the receiver Global Positioning System (GPS)-based measurements. The practical use of the system GPS involves various inherent problems of the signal. Two of the most important problems are the TIE and the instantaneous loss of the signal of the GPS by a small interval of time, called "holdover". 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. Basic holdover algorithms are discussed along with their most critical properties. Efficiency of the predictive filter in holdover is demonstrated in applications to GPS-based measurements of the TIE.
