AIS (Automatic Identification System) onboard a ship is a maritime safety system that:
# Primary Functions
1. *Broadcasts*: Vessel's identity, position, course, speed and other relevant information.
2. *Receives*: Similar information from nearby vessels.
3. *Displays*: Real-time data on surrounding vessels.
# Key Features
1. *Vessel tracking*: Accurate positioning and movement monitoring.
2. *Collision avoidance*: Alerts crew to potential collisions.
3. *Traffic management*: Enhances situational awareness.
4. *Search and rescue*: Facilitates emergency response.
# Mandatory Requirements
1. *International regulations*: SOLAS (Safety of Life at Sea) requires AIS on:
- Passenger ships
- Tankers
- Cargo ships (>500 GT)
- Ships carrying hazardous materials
1. *Class and flag state regulations*: Additional requirements may apply.
# Types of AIS
1. *Class A*: Mandatory for commercial vessels (SOLAS-compliant).
2. *Class B*: Optional for recreational vessels.
3. *AIS Base Station*: Shore-based stations for monitoring maritime traffic.
# Benefits
1. Improved safety
2. Enhanced situational awareness
3. Reduced risk of collisions
4. Efficient traffic management
5. Environmental monitoring (e.g., oil spill detection)
# Components
1. AIS transponder
2. GPS antenna
3. VHF antenna
4. Display unit (e.g., ECDIS, radar)
5. Interface for integrating with other ship systems (e.g., ECDIS, radar)
# Standards and Certifications
1. IEC (International Electrotechnical Commission) standards
2. ITU (International Telecommunication Union) recommendations
3. FCC (Federal Communications Commission) regulations
4. Type approval from flag state administrations
# Installation and Maintenance
1. Professional installation
2. Regular software updates
3. Periodic performance checks
4. Annual inspections
