Navigational Equipment

Types of Navigational Equipment

Global Positioning System (GPS)
- Satellite-based navigation system.
- Provides accurate location data (latitude, longitude).
- Used in vehicles, maritime, and aviation.
Radar
- Uses radio waves to detect objects and their distance.
- Commonly used in maritime navigation to avoid collisions.
Sonar
- Sound propagation used to navigate and detect objects underwater.
- Essential for submarines and marine exploration.
Compasses
- Magnetic compasses indicate magnetic north.
- Gyrocompasses align with true north and are used in ships and aircraft.
Charts and Maps
- Nautical charts provide details about water bodies, coastlines, and hazards.
- Topographic maps help in land navigation.
Lighthouses and Buoys
- Lighthouses provide visual navigation aids, marking coastlines or hazards.
- Buoys mark navigational routes and indicate water depths.
Inertial Navigation Systems (INS)
- Uses motion sensors to track position without external references.
- Common in aircraft and spacecraft.
Automatic Identification System (AIS)
- Maritime tracking system for identifying and locating vessels.
- Enhances maritime safety and traffic management.

Key Functions

Positioning: Determines the exact location of the user.
