Marine Navigation and Surveying Developments

Gérard Lachapelle

Abstract:	The major marine positioning tasks currently required are reviewed. The marine navigation and positioning requirements for these tasks are presented. Emerging requirements are also discussed. The status and performance of major ground- and satellite-based marine navigation and positioning methods are described. The emphasis is placed on the rapid developments which have occurred with GPS equipment, software and methods and which have resulted in novel marine positioning applications. These include (i) the establishment of DGPS services using marine radiobeacons, (ii) the development of narrow correlator spacing C/A code and P code or codeless- based post-mission and real-time kinematic cm- level accuracy methods, and (iii) the development and testing of multi-antenna systems for attitude determination at the 0.05” to 0.5” accuracy level.
