Page 30: Abbreviations And Definitions
Abbreviations and Definitions Acknowledge Automatic Identification System - A shipborne broadcast transponder system in which ships continually transmit their position, course, speed and other data to other nearby ships and shoreline authorities on a common VHF radio channel. AIS-SART Automatic Identification System-Search And Rescue Transponder AtoN Aid to Navigation BAUD... - Page 31 Heading - The direction, in which the vessel is pointed, expressed as angular distance from north clockwise through 360 degrees. HEADING should not be confused with COURSE. The HEADING is constantly changing as the vessel yaws back and forth across the course due to the effects of sea, wind, and steering error.
- Page 32 Range RX is the telegraph and radio abbreviation for “receive” Search And Rescue Signal-to-Noise ratio (SIN). Quantitative relationship between the useful and non-useful part of the received satellite signal. A high SIN indicates a good receiving condition. Speed Over Ground – Speed in relation to the seabed. SOTMA Self Organized Time Division Multiple Access -An access protocol, which allows autonomous operation on a data link while automatically resolving transmission conflicts.
