The em-trak SART 100 is an aid to navigation and must not be relied upon to provide accurate navigation information. AIS is not a replacement for vigilant human lookouts and other navigation aids such as Radar. The performance of the SART 100 may be seriously impaired if not installed as instructed in the user manual, AIS SART ? AIS SART is a distress position transmitting device designed for fast search and rescue activity. It sends distress signal with an exact GPS location using the AIS system.
AIS-SART transmits on dual channel, CH2087 and CH2088. The maximum communication range depends on both heights of transmitting antenna and receiving antenna. A=2.5(√H+√h) （nm） H and h refer to the heights in meter of antennas above sea. As required, AIS-SART should cover at least 5nm on the condition that transmitting with other nearby ships and VTS stations. AIS transponders use two different frequencies, VHF maritime channels 87B (161.975 MHz) and 88B (162.025 MHz). SCOUT has designed the KS-30 antenna to be tuned on the AIS frequencies. Perfectly suited to the AIS radar and AIS Engine.

AIS-SART was added to Global Maritime Distress Safety System regulations effective January 1, 2010. A search and rescue transponder (SART) is a self-contained, waterproof transponder intended for emergency use at sea. These devices may be either a radar-SART, or a GPS-based AIS-SART (automatic identification system SART). AIS stations should be designed for operation in the VHF maritime mobile band, with 25 kHz bandwidth, in accordance with RR Appendix 18 and Recommendation ITU-R M.1084, Annex 4.
The Automatic Identification System (AIS) is the biggest advance in marine navigation since AIS uses two VHF frequencies;. 1. AIS SARTs are ideal for close.
Satellite AIS (S-AIS) tracks the location of vessels in the most remote areas of the world, especially over open oceans and beyond the reach of terrestrial-only AIS systems.

The batteries of the SA70 AIS SART will last at least 96 hours when activated. To save battery capacity in case of a situation where the unit is needed, the use should be limited to tests and emergency situations.

However, you can u se the RPi clock to calibrate the RTL-AIS service to account for any frequency offset. Note: The frequency offset is measured in Parts Per Million (PPM). 2014-03-27 About product and suppliers: Alibaba.com is a one-stop-shop for everyone who wants to purchase ais sart from the ease of their homes and being assured of standard quality.
When started, the Tron AIS-SART sends its position data in an ordinary AIS message. In addition the Tron AIS-SART sends a safety text message every forth minute, containing text: “AIS SART”. This will be received by other AIS systems within the range.

AIS is a transponder system for ships intending to increase the safety at sea. It operates in the VHF band. The two frequencies used worldwide are 161.975 and 162.025 MHz (channels 87B and 88B, or AIS1 and AIS2). An AIS transmitter regularly transmits the ship's position, heading, speed and MMSI (the unique maritime identification number).
