Application of GPS for fisheries

Abstract

Selective Availability (SA) in order to degrade the position accuracy of Global Positioning System (GPS), was turned off in May, 2000. This improved new positioning accuracy of GPS is reported. And, the GPS compass for ship heading sensor and a small drifting buoy's monitoring system by using low earth orbit (LEO) communication satellite are introduced as the recent unique applications of GPS for fisheries. The results of the evaluation test used these GPS application instruments are also discussed.
