Sensitivity Analysis of an Integrated NAVSTAR GPS/INS Navigation System to Component Failure

This paper examines the performance of an integrated GPS/INS navigation system with respect to component failures. The paper is divided into three sections. The first section details the system configuration by which the navigation components are integrated. The second section examines the modelling methods used to simulate each of the components and the third section analyzes the simulation results. Four modes of component failure are investigated. They are GPS outage, baro‐altimeter failure, inertial failure and satellite obscuration. 1983 Institute of Navigation
