Abstract: This paper about vessel Positioning System. Using this application We can determined vessel location in sea with help of longitude and latitude as
Well as we can get our speed, UTC time, and many other parameter which helpful in sea related to vessel location.
I-INTRODUCTION
VPS (Vessel Positioning System) is the System which works on the Basis of GPS (Global Position System). With help of GPS receiver we can determine the location of vessel anywhere in sea. VPS indicated its own position in sea with GPS modulo. Using the Vessel Positioning System (VPS, a process used to establish a position at any point on the sea) the following two values can be determined anywhere on Earth
1. Vessel’s exact location (longitude, latitude and height co-ordinates) accurate to within a range of 20m to approx.
2. The precise time (Universal Time Coordinated, UTC).
Speed and direction of travel (course) can be derived from these co-ordinates as well as the time. The coordinates and time values are determined by several satellites orbiting the Earth.
II-NMEA 0183 PROTOCOL The National Marine Electronics Association (NMEA) developed a standard over 20 years ago that defines the interface between various pieces of marine electronic equipment and navigational computers, allowing them to talk together and share vital information.
NMEA data is transmitted from an information source such as a GPS, depth sounder, or gyro compass etc. These data sending devices are called “Talkers”. Equipment receiving this information such as a chart-plotter, radar, PC or NMEA display is called a “Listener”.
1.1 Communication specification
The NMEA 0183 standard is a purely digital data transmission scheme, using ‘1’s and
