Navigation Services: A Measured, Extendible and Affordable Approach to Satellite-Based Navigation

Daniel J. Brophy, Fred M. Bay and Randy Hartman

Abstract:	Safe, orderly growth of civil aviation well into the 21st century requires a transition to Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) − the creation of a modern, seamless, global air traffic management system. The International Civil Aviation Organization (ICAO) has outlined a vision for a future CNS/ATM system that includes expanded use of satellite communications and navigation. To realize this vision, ICAO is developing Standards and Recommended Practices (SARPS) for the GNSS that address all the requirements for civil aviation navigation. These standards define requirements for Differential Global Positioning System (DGPS) navigation systems that support various levels of navigation performance and include both wide-area and local-area augmentations. Augmentation systems are required to monitor GNSS signal integrity and perform a differential correction to improve accuracy. Successful provisioning of a navigation augmentation service is critical to achieving CNS/ATM. The transition from conventional ground navigation aids to space-based navigation aids can be a significant and costly undertaking. It requires a thoughtful, measured and incremental deployment approach. This paper describes the preliminary technical trades for a system architecture proposed by a newly formed, private navigation service company, called Synchronetics™ .
