A GPS-Based Integrated Sensor Approach to the Precision Pointing Problem

摘要

This paper presents an integrated sensor system for determining the azimuth and pitch of a platform in post- mission. The sensors include a Global Positioning System (GPS) dual-antenna fixed-baseline system, coupled with a fibre-optic gyro (FOG) and a combined compass and tilt meter. The integrated sensor approach was chosen to overcome limitations in GPS-only system stemming from satellite line-of-sight dependence an carrier phase integer ambiguity resolution.
