Abstract

Ever since the beginning of time, man has searched for better navigational aids. The NAVSTAR Global Positioning System (GPS) represents the culmination of years of research and development. The system utilizes state of the art satellite communication enabling all weather worldwide navigation never before possible. The system provides position accuracies within 9 meters; velocity information within 0.1 m/sec; time data within 100 nanoseconds. With GPS still in the infancy stages, the potential applications remain limitless. Many James Bond type scenarios become very realistic -a display in every car showing exactly where the car is and an electronic map showing possible courses. The application of GPS is limited only by one's own imagination. This thesis explores the three GPS areas: 1) system concept; 2) signal structure; and 3) Digital Signal Processing (DSP) techniques. The GPS information presented allows the reader to become familiar with the NAVSTAR system concept and the application of a DSP technique in a GPS receiver design. By capitalizing on the rapid electronics
