What is the primary function of a boat's GPS system?

The primary function of a boat's GPS system is to provide location data and navigation routes. A GPS, or Global Positioning System, utilizes a network of satellites to determine a vessel's precise location on Earth, often represented in terms of latitude and longitude. This capability is crucial for mariners as it enables them to chart their course effectively, avoid hazards, and reach their destination safely.

The navigation functions of GPS are complemented by features that can provide route planning, waypoint marking, and real-time tracking, ensuring that boaters can navigate waterways efficiently and with confidence. This technology greatly enhances safety and efficiency in marine travel, making it an invaluable tool for recreational and commercial vessels alike.
