Abstract:
GPS (Global Positioning System) is increasingly being used for a wide range of applications. It provides reliable
positioning, navigation, and timing services to worldwide users on a continuous basis in all weather, day and night,
anywhere on or near the Earth. GPS is made up of three segments: Space, Control and User. GPS has become a
widely used aid to navigation worldwide, and a useful tool for map-making, land surveying, commerce, scientific
uses, tracking and surveillance, and hobbies such as geocaching and way marking. None of the present GPS systems
satisfy the requirements for the safety of civilian navigation in the sea as the maritime boundary of a country cannot
be marked.
This paper deals on the versatility and the usefulness of a GPS device in the sea. The main objective of the paper is
to help the fishermen not to navigate beyond other country’s border. If a fisherman navigates beyond the country’s
border, an alarm is generated indicating that the fisherman has crossed the border. Additionally, a GSM transmitter
interface will send a message to base station located on the shore indicating that a vessel has crossed the border.
Thus guards in the shore can assist and provide additional help to those fishermen if needed.
Keeping in mind about lives of Indian fishermen, this device has been created to help them not to move beyond
Indian. On the whole, it is an attempt to build a suitable device for the fishermen at a reasonably low cost.
