Introduction to GPS

The Global Positioning System (GPS) is a space-based navigation system that consists of 24 navigational satellites in 6 different orbits that provide location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

The significance of GPS on ships is immense. Navigation is one of the most critical aspects of a ship’s operations, and GPS provides accurate and reliable information on a ship’s position, course, and speed. With GPS, a ship’s crew can determine its exact location, plan and execute safe routes, avoid hazards, and navigate through rough weather conditions.

GPS also allows for efficient voyage planning and management, saving time, and fuel, and reducing operational costs. Additionally, GPS enables search and rescue operations by providing accurate information on a ship’s location in case of emergencies.

Overall, GPS has revolutionized navigation and safety at sea, making maritime operations more efficient and secure.
