Geolocation Via Satellite: A Methodology and Error Analysis

Abstract

This report is directed towards the problem of geolocating the transmitter or receiver of a satellite-relayed signal; however, its methodology is appropriate to general estimation theory. A unified treatment of nonlinear least squares estimation, dominated by techniques for analyzing the estimate accuracy, is presented. In this context, appropriate equations are derived for doppler measurements as a function of the ground stations and satellite orbit elements. These may be used to determine the satellite orbit as well as ground station locations. A general model for motion on an oblate earth is also developed. Keywords: Satellite communications, Least squares estimation, Doppler measurements.
