Global Navigation Satellite System Requirements for Vessel Traffic Services

W.R. Cairns and J.M. Sollosi

Abstract:	ABSTRACT: A Global Navigation Satellite System (GNSS) has the potential to offer all users highly accurate positioning and navigation information on a worlwide basis, with high system integrity and availability. What can this navigation resource offer vessel operators, Vessel Traffic Services and waterways management authorities? We know that GPS offers 1OOm accuracy and DGPS better than 5m (2drms). What is the relationship between this accurate position information and the Electronic Chart Display and Information Systems? The U.S. Coast Guard VTS in Alaska's Prince William Sound uses DGPS as a position source for its Automated Dependent Surveillance System. Could the success of this effort be extrapolated to a regional or even a global VTS? The aviation community uses a type of user fee to fund much of its safety-related systems. Can mandatory VTS participants offer a funding source for the GNSS? What are the technical and the legal/political issues affecting further deployment of DGNSS-based transponders or automated dependent surveillance?
