A Real-Time Bi-Directional Differential Global Positioning System

by Shetty, Ranjeet S.

Abstract (Summary)
Traditionally, Differential Global Positioning System (DGPS) provides corrections to enable high accuracy position solution to mobile users. The Local Area Augmentation System (LAAS) employs DGPS to obtain precise positioning of aircraft for various levels of landing categories in the airport vicinity. Unrelated to LAAS, some remote-positioning systems transmit measurements from a mobile user to another location to determine the state of the mobile user remotely. The Bi-directional DGPS proposed here would enable both of these features simultaneously within the same architecture. The purpose of this research was to demonstrate a Bi-directional DGPS, within a prototype LAAS, that integrates both DGPS and remote-positioning capabilities. The Bi-directional DGPS was successfully demonstrated at the Ohio University Airport using both a van and an aircraft as a mobile user with a fixed supporting ground-based station. This thesis presents the architecture, results and conclusions of these demonstrations.
