GMT Greenwich Mean Time. See also UNIVERSAL TIME COORDINATED. GPS SYSTEM TIME Time corrected to Universal Time Coordinated (UTC) and used as the time standard by the user segment of the GPS system. 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. IALA International Association of Marine Aids to Navigation ans Lighthouse Authorities IEC International Electro-technical Commission. IEC 61162-1 Maritime navigation and radiocommunication equipment and systems – Digital interfaces Single Talker- Multiple listeners: Closely related to NMEA0183 version 2.3, communication at 4800 baud. Definition of both electrical and protocol to be used. IEC 61162-2 Maritime navigation and radiocommunication equipment and systems – Digital interfaces Single Talker- Multiple listeners, High speed transmission: Closely related to NMEA0183HS version 2.3, communication at 34800 baud. Definition of both electrical and protocol to be used. IEC 61993-2 Maritime navigation and radiocommunication equipment and systems – Automatic Information Systems (AIS) Definitions of the sentences used for AIS in addition to those mentioned in IEC 61162-1 and IEC 61162-2. IMO International Maritime Organisation INTERFACE Electronic circuits that permit the passage of data between different types of devices; For example, the speed and heading interface circuit permits data from a speed log and compass to pass to the navigator processor. IP Internet Protocol (IP) is the central, unifying protocol in the TCP/IP suite. It provides the basic delivery mechanism for packets of data sent between all systems on an internet, regardless of whether the systems are in the same room or on opposite sides of the world. All other protocols in the TCP/IP suite depend on IP to carry out the fundamental function of moving packets across the internet. ITDMA Incremental Time Division Multiple Access -Access protocol for pre-announced transmissions of temporary or nonrepeatable character. It is also used during data link network entry. ITU International Telecommunication Union. LED Light Emitting Diode. LSS Logical AIS Shore Station. A LSS is a software process, which transform the AIS data flow associated with one or more PSS into different AIS-related data flow. The SW process of a logical AIS station can run on any appropriate computer at any appropriate place. 82694_Op&Ins MAN_RA2500_D 4
MMI Man Machine Interface NMEA National Marine Electronics Association. The NMEA electronics interface specifications have been developed under the auspices of the Association. The NMEA 0183 is an internationally recognized specification for interfacing marine electronics. NMEA 0183 version 2.3 is identical to lEC 61162-1. POLLED MODE A transponder is in a polled mode during a request-response session only. Distinguish this from a station, which is polled into certain slots. This station is first polled and then enters assigned mode. POSITION UPDATE The redefining of position by analysis of satellite orbital data as referenced to time. PROCESSOR The processor circuit card in the console that controls system operations and computes the positioning/navigation solutions. PROMPT A message on the display instructing the operator to make a keyboard entry. PSS Physical AIS Shore Station. The PSS is the most basic AIS-related entry, which can exist on its own in a real physical environment, as opposed to an AIS base station or AIS repeater station. PULSE SPEED SENSOR Speed log whose speed output signal is defined by a pulse mte output. RATDMA Random Access Time Division Multiple Access -Access protocol for transmissions which have not been preannounced. This is used for the first transmission during data link network entry or for messages of non-repeatable character. REFERENCE COMPASS The compass against which the steering compass (see STEERING COMPASS) may be calibrated. REFERENCE ELLIPSOID A mathematical description of the Earth's ellipsoidal shape (see ELLIPSOID), which is the reference frame for positioning computation. RESET To return stored values to either the default value or zero in memory. RMS See ROOT MEAN SQUARED. ROOT MEAN SQUARED (RMS) A statistical measure of probability, stating that an expected event will happen 68% of the time. In terms of position update accuracy, 68 position updates out of 100 will be accurate to within specified system accuracy. SENSOR A device that detects a change in a physical stimulus and turns it into a signal that can be measured. 82694_Op&Ins MAN_RA2500_D 5
