Study on Positioning of GPS Receiver Built-in Buoy Using Communication Satellite

Abstract

The buoy built-in GPS receiver for ORBCOMM system was developed recently. The ORBCOMM system is a kind of remote monitoring system using the communication satellite. Using this system, the drifting position of buoy is able to be monitored on real time mostly. But the system performance is not evaluated sufficiently in actual sea condition. In this paper, we explained the concept of this new satellite monitoring system, and the results of verification experiments on positioning accuracy and GPS data communication delay time conducted at sea. And, a proposal of a small single GPS receiver added to the buoy in order to improve the positionig accuracy is made and the experimental results is also discussed.
