The AIS-SART is a self-contained radio device used to locate a survival craft or distressed vessel by sending updated position reports using a standard Automatic Identification System (AIS) class-A position report. The position and time synchronization of the AIS-SART are derived from a built in GNSS receiver (e.g. GPS). Shipboard Global Maritime Distress Safety System (GMDSS) installations include one or more search and rescue locating devices. These devices may be either an AIS-SART (AIS Search and Rescue Transmitter) (from January 1, 2010), or a radar-SART (Search and Rescue Transponder). The AIS-SART derives position and time synchronization from a built in GNSS receiver. Once per minute, the position is sent as a series of eight identical position report messages (four on 161.975 MHz and four on 162.025 MHz). This scheme creates a high probability that at least one of the messages is sent on the highest point of a wave. AIS SARTs are typically cylindrical and brightly colored. A typical model is 251mm (about 10 inches) high and weighs 450g (about a pound).〔(【引用サイトリンク】url=http://www.jotron.com/Kategori/Maritime-Products/AIS-SART--Radar-SART/485.php )〕 The specification (IEC 61097-14 Ed 1.0) for AIS-SART was developed by the IEC's TC80 AIS work group. AIS-SART was added to the GMDSS regulations effective January 1, 2010. ==See also== * Emergency Position-Indicating Radio Beacon (EPIRB) * Civil Air Patrol (US Air Force Auxiliary) * Long-Range Identification and Tracking (LRIT) * Marine VHF radio * Automatic Identification System * Global Maritime Distress Safety System 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AIS-SART」の詳細全文を読む スポンサード リンク
