Study Notes
Electronic Chart Display and Information (ECDIS)
- Digital alternative to traditional paper charts for maritime navigation.
- Enhances safety and efficiency in navigation through real-time digital displays.
Global Positioning System (GPS)
- Navigation system determining precise locations (latitude, longitude, altitude) anywhere on Earth.
- Relies on a network of satellites orbiting the Earth.
- Integration with heading sensors and speed logs improves navigational accuracy.
Positioning Requirements for GPS
- Requires unobstructed scanning and clear view for effective operation.
- Must have adequate space and no interference from structures or equipment.
Construction and Installation of GPS
- Ships must install two independent GPS receivers for redundancy and reliability.
- GPS should integrate with other onboard systems like ECDIS and AIS.
- Equipment must be regularly updated to display the latest information.
Radio Detection and Ranging (RDAR)
- Navigational tool for detecting and tracking vessels, land masses, and obstacles.
- Operates using radio waves, essential for situational awareness.
Positioning Requirements for RDAR
- Needs a clear view ahead and unobstructed scanning for functionality.
- Should be free of interference from other equipment.
Construction and Installation of RDAR
- Radar antennas must be optimally installed to minimize blind spots.
- Integration with other navigational aids, such as AIS and ECDIS, enhances effectiveness.
Automatic Identification System (AIS)
- Enables vessels to exchange information about their position, identity, course, and speed.
- Sends and receives short safety messages; supports communication between vessels and shore stations.
- Operates using radio frequencies.
Positioning Requirements for AIS
- Requires unobstructed views and adequate space for optimal operation.
- Must have no interference from other structures or electronic equipment.
Construction and Installation of AIS
- Radar antennas need placement to avoid blind sectors.
- Integration with navigational systems like ECDIS and ARPA is crucial for performance.
Automatic Radar Plotting Aids (ARPA)
- Provides automated tracking of multiple targets, aiding in collision avoidance and navigation.
- Enhances situational awareness by displaying information about nearby vessels and conditions.
