Doppler Speed Log works on the principle of Doppler shift in frequency measurement i.e. an apparent change in frequency received when the distance between source and observer is changing due to the motion of either source or observer or both. Doppler Log is used to indicate speed and distance are…View More Performance Standards – Doppler Speed Log
Autopilot is basically used when ship has to steer a set course for a long time without alteration because any deviation from the set course is controlled electronically and automatically. This will not only relieve the helmsman from steering duties but is also more efficient because as soon as the…View More Performance Standards – Autopilot and Heading Control System
LRIT stands for Long Range Identification and Tracking. While meeting the general requirements for ship borne radio equipment forming part of the global maritime distress and safety system (GMDSS) and for electronic navigational aids, the LRIT should comply with the following minimum requirements: IMO PERFORMANCE STANDARDS FOR LONG RANGE IDENTIFICATION AND TRACKING SYSTEM (LRIT)…View More Performance Standards – LRIT
Automatic Identification System (AIS) is a system which provides a means whereby ships exchange information such as ID, position, course, speed etc, with all other ships in vicinity ans shore stations. IMO has specified performance standards for AIS fitted on ships, these performance standards help avoid sub standard ships and…View More Performance Standards – AIS
Both Long Range Identification and Tracking (LRIT) and Automatic Identification System (AIS) have different purpose altogether but are important to ships at sea. AIS is an broadcast system, whereas LRIT is reporting system. AIS is a system which provides a means whereby ships exchange information such as ID, position, course, speed…View More Difference between LRIT and AIS System
