![]() SART will be carried and used in a liferaft to indicate a survivors position in the water. SART has a unique MMSI number that starts with 970 followed by 6 numbers making a 9 digit MMSI number ie 970991234. is in its early stages of developement and may also be able to detect the transmissions.Īs well as updatable positional information the A.I.S. receiver will be able to detect the A.I.S. Only vessels and shore stations fitted with an A.I.S. SART incorporates an onboard GPS which will transmit positional data every minute. The Automated Identification System transmits data on the VHF channels 87 and 88. The radar reflector MUST NOT be used at the same time as the SART.Ī second type of SART is on the market and this is aimed at the A.I.S. Once contact has been made with the Liferaft and the SART turned off, erect the radar reflector to aid location. In poor visibility it may be necessary to make several passes from different directions and triangulate the bearings before the position of the SART can be accurately determined.

Obtaining an accurate bearing to the casualty becomes increasingly harder as the range decreases and the 'blips' become arcs, and impossible when the arcs become concentric circles. It has been found that the best results for locating a SART can be obtained by setting the search radar to a 12 miles range, before switching to six miles as the range decreases. At about one mile range, these arcs will become a series of concentric circles. Within 1 mile of the SART the screen is clutteredĪs the range decreases the 'blips' will grow, becoming arcs. Initial detection of a SART indicating range and bearingĪs the SART gets closer the dots turn to arcs SART's are triggered by 9GHz radars from different sources. An aircraft at 3,000 feet could detect the same SART from about 48 miles. A Lifeboat searching for a life raft can expect to make contact at about five to six miles. The detection range of a SART varies depending upon the height of the radar and the height of the SART. This transmission will be displayed on the radar screen of the rescue vessel as a line of up to twelve 'blips' along the bearing of the SART, with the first echo as the target. Once a SART has been activated, it will react to a 9 GHz radar signal, sending back its own transmission. When abandoning a vessel fitted with its own radar, the radar must be switched off before deploying the SART or the SART will be prematurely activated. If a radar reflector is in place on the life raft, it must be removed when the SART is deployed as it can reflect radar signals from a search vessel before they cause the SART to react. Once the SART has been switched on it should be attached to the highest point available, normally this will be achieved by fixing it to a supplied, one metre long telescopic pole and positioning this through the life raft's antenna opening. ![]() When deploying a SART, read the manufacturer's instructions carefully. SART's are checked on a monthly basis to ensure correct operation by activating the test facility (the test is a low power transmission).Ī SART can be checked by briefly activating it using the test facility and subjecting it to one or two passes of the ship's radar, however it is important that the local vessels are informed before this takes place. SART's are normally carried on the ship's bridge or similar convenient place where they are readily accessible. SARTS, (Search and Rescue Radar Transponders), are location beacons that send a homing signal when interrogated by a 9 GHz radar. The Echomax A03i is built from 28 components interconnected with 17 ultrasonic welding operations inside a three piece airtight 24" round PVC case, inflated orally or by pump.Search and Rescue Radar Transponders (SARTS) The Echomax A03i Inflatable specifically designed for liferaft deployment, they can be safely vacuum sealed into a liferaft then those designed from rigid metal plates. ![]() The 18 inch Echomax octahedral array is built into a round inflatable radar reflector for easy deployment under extreme conditions.
