The vessels and rescue planes nearby can receive the position reports sent by AIS-SART to easily locate the life raft in distress. NAS-1000 AIS-SART conforms to the requirements set in IMO IMSC 246 (83). The Nasa Marine AIS SART Plotter is the first stand alone AIS receiver / plotter specifically designed for the leisure boat market. The unit consists of a dual frequency AIS receiver, demodulator, signal processor and a backlit matrix display. It receives an NMEA input (RMC) from the boats GPS which puts the user at the centre of a radar style screen. A COG pointer is selectable by the user AIS or the Universal Shipborne Automatic Identification System (AIS) is a ship transponder system that is currently used by most of the commercial shipping industry. AIS uses two marine VHF channels.

This scheme creates a high probability that at least one of the messages is sent on the highest point of a wave. A SART will only respond to a 9 GHz X-band (3 cm wavelength) radar. It will not be seen on S-band (10 cm) or other radar. Shipboard Global Maritime Distress Safety System (GMDSS) include one or more search and rescue locating devices. The radar-SART may be triggered by any X-band radar within a range of approximately 8 nautical miles (15 kilometers). An AIS-SART, being an AIS transmitter, has a unique identi er, (an MMSI) using the format 970xxyyyy, where xx is the manufacturer ID from 01 to 99 and yyyy is the sequence number assigned by the manufacturer from 0000 to 9999.

The test from this unit can also be seen as the SART: AIS transponder for emergency alert use only (has no receive functionality) that transmits a special emergency transmission which takes priority over all other AIS transmissions. Available in vessel versions (SART) or personal versions (PLB) with the difference being size and range. SART is a small, battery powered, omni-directional radar receiver and transmitter, it can be detected by ship or aircraft radars operating in the frequency band 9.2-9.5 GHz. On receiving a signal from the radar, the device transmits a series of response signals. Advanced technology maximises range.

Any vessel or station which can receive and detect an AIS signal will also detect an AIS-SART.

AIS-SART was added to Global Maritime Distress Safety System regulations effective January 1, 2010. The AIS search and rescue (SAR) aircraft station should transmit position report Message 9, and static data using Message 5 and Messages 24A and 24B. 2.1.5 Repeater station 2.1.6 Automatic identification system search and rescue transmitter The AIS SART station should transmit Message 1 and Message 14 using the burst transmissions as EPIRB’s are small portable devices using the global COSPAS-SARSAT Satellite System and sending signals on the 406MHz frequency, whereas the SART devices are portable radar transponders operating on the radar ”X” and ”S” frequency bands. EPIRB’s are small portable devices using the global COSPAS-SARSAT Satellite System and sending signals on the 406MHz frequency, whereas the SART devices are portable radar transponders operating on the radar ”X” and ”S” frequency bands. AIS transponders and receivers use two VHF radio frequencies: 161.975 MHz (AIS1, or channel 87B) and 162.025 MHz (AIS2, or channel 88B). The USCG has asked the Federal Communications Commission to authorize any US vessel to operate AIS on these two channels under its existing ship station license. AIS SART(Search and Rescue Radar Transponder) Model: FT-9500 Frequency: 161.975~162.025 MHz Type of Transmit: SOTDMA Transmit Power: 30dBm±1.5dB Certificate: CCS To aid SAR vessels and aircraft in locating people in distress, the specification (IEC 61097-14 Ed 1.0) for an AIS-based SAR transmitter (AIS-SART) was developed by the IEC's TC80 AIS work group.

The AIS-SART with ID code 970000003 was mounted on “Oscar”, a simulated person floating in the water. The results obtained from this unit shows that AIS-SART used as a man over board alert has a good potential as a life saving device.

i McMurdo Smartfind S5 AIS SART Part number 92-001-001A The AIS SART5 transmits messages in NMEA format on the two AIS frequencies AIS1, 161.975 AIS SART Plotter The Nasa Marine AIS SART Plotter is the first stand alone AIS receiver / plotter specifically designed for the leisure boat market. The unit rescue operations in the frequencies listed in sections 7, 8 and 9 of the instrument.

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.
