Computation of Positions Error Signals in Augmented INS/GPS Syetem Based on Wavelet Analysis

Abstract

Integrated systems based on Inertial Navigation System (INS) and the Global Positioning System (GPS) generated increased interest in the airborne survey and remote sensing community over the past few years. Where, with full operational GPS capability, it has been recognized that an optimal combination of GPS with inertial navigation brings a number of advantages over stand-alone inertial or GPS navigation.This paper aims at introducing GPS and INS system integration approach for fusing data utilizing wavelet analysis. Where the wavelet used to compare the sensers outputs at different resolution levels, for several types of errors in INS and GPS, to smooth and predect the INS erros.
