1. GPS Overview

Global Positioning System IS based on the radio navigational system and satellites which provide an
unlimited number of users with accurate three dimensional positions, velocity and time in straight 24 hours,
worldwide coverage, under any weather condition.
GPS has two types of Positioning such as 3D and 2D.
3D Positioning is used to using in Airplane, which is required three positioning -Latitude, Longitude, Height.
In this positioning, It s required 4 satellites to make the position.
2D Positioning is to using Vessel/Ship, which is used only Latitude, Longitude without height.
In case of 2D positioning, It s required only 3 satellites to receive signal, then time zone for positioning will
be extended.
GPS gives more accurate positioning result always due to receiving signal from satellites, which are
revolving around the earth.
The GPS Plotter has received information from satellites and display own ship position, bearing, time, and
speed out of LCD screen.
Further it provides information for navigation on sail, more clear data together with port map and
Latitude/Longitude, Track, Event Mark based on High-resolution LCD implemented.
