An autonomous navigation scheme using global positioning system/geomagnetism integration for small satellites

Abstract

This paper presents a low-cost scheme of an autonomous integrated global positioning system (GPS)/geomagnetism navigation system for small satellites to improve the performance of stand-alone GPS or geomagnetism navigation using the existing hardware equipment. In the paper, the use of the GPS and autonomous navigation systems based on magnetic field measurements (ANSMFM) to determine low Earth orbits (LEO) is discussed. The paper combines the GPS with the ANSMFM and constructs a new autonomous GPS/geomagnetism integrated navigation system (AGGINS) using two integration approaches: loosely and tightly coupled integrations. The improved extended Kalman filter completes the data processing for the optimal integration. The paper analyses the benefits of the AGGINS and finally gives simulation results that demonstrate the effectiveness and practicability of the method.
