Study of the Global Positioning System for Maritime Concepts/Applications: Study of the Feasibility of Replacing Maritime Shipborne Navigation Systems with Navstar

摘要

A geostationary reference satellite (REFSAT) that broadcasts every four seconds updated GPS satellite coordinates was developed. This procedure reduces the complexity of the GPS receiver. The economic and performance payoffs associated with replacing maritime stripborne navigation systems with NAVSTAR was quantified and the use of NAVSTAR for measurements of ocean currents in the broad ocean areas of the world was evaluated.
