Salah satu alatnya adalah radar-SART (Search and Rescue Transponder). Radar-SART ditempatkan di sekoci penyelamat, SART hanya bereaksi terhadap 9 ghz x-band (3 cm radar panjang gelombang).
Whathappens when you activate an EPIRB or PLB. Distressed mariner/outdoor adventurer/pilot activates beacon (EPIRB, PLB, ELT). The beacon transmits a 406 MHz emergency message containing your Unique Identifier Number (UIN) to the LEOSAR (polar orbiting) and GEOSAR* (geostationary) satellite systems. The satellites relay the 406 MHz emergency
Securethe EPIRB to the survival craft and mount the SART in a position to maximize its elevation. Which action is the most appropriate action for a GMDSS radio Operator to take in a Distress situation where immediate help is needed, but the vessel is not sinking nor needs to be abandoned?

DSCis considered the automated watch on distress channels running on VHF, MF/HF radios. The satellite communication is based on satellite network that reaches up to sea area A3. Emergency Position Indicating Radio beacon's (EPIRB) and Search and Research transponders (SART) are sending out distress and locating signals under emergencies.
Insimple terms, an EPIRB 'raises the alarm and indicates a position' and the SART is used by rescue craft searching in that area. SART stands for Search And Rescue Transponder. Unlike an EPIRB (Electronic Position Indicating Radio Beacon) which independently broadcasts a radio signal for satellites to repeat to a ground station, a SART only broadcasts a response signal when it is interrogated by radar.
MD2C5g. SART or Search and Rescue Transponder is extremely vital equipment on the ship as it performs the job of a signal-man. It is a vital machine during distress for it helps in locating the position of the vessel in case it goes off-track. SARTs are made of waterproof components which protects them against damage by water. SARTs are essentially battery-operated, hence can be operative for a long time. SARTs are of use in ships, lifeboats and liferafts. They are the most supportive machines in case of an unprecedented emergency. SARTs are designed to remain afloat on the water for a long time in case the vessel finds itself submerged in water. The bright colour of SARTs enables their quick detection, whereas the combination of transmitter and receiver enables it to transmit as well as receive radio signals. SART machines have been instrumental in rescuing several crafts and ships by reacting to the search signal sent from an X-band radar, typically of 9 GHz. These signals are known as homing signals. The response is usually displayed on radar screens as a sequence of dots on an X band-radar, which helps rescuers reach the vessels in time. Watch video on SART As mentioned earlier, SART is basically an electronic device that automatically reacts to the emission or interrogation by radar. This enhances the visibility of the party in need of assistance on the radar display PPI. They operate on the 9 GHz band and only transmit when they are switched on when interrogated by radar. SART – General features, location and functioning SART is made of fibre-reinforced plastic which can withstand and bear the prolonged exposure to sunlight and extreme weather conditions It is capable of floating free of the survival craft International orange in colour SART is mounted on a mounting bracket which is fixed to a bulkhead on a ship, on the bridge It operates on the 9GHz frequency band to GHz and generates a series of clips on the radar it is interrogated by 3 cm/X Band radar. They can either be portable or fixed permanently into the survival craft The SART is activated manually and hence responds only when interrogated When activated in a distress situation, the SART responds to radar interrogation by transmitting a signal which generates 12 blips on the radar and turns into concentric circles as the range between the two reduces On the PPI, the distance between the blips will be miles This signal is very easy to spot than a signal echo from say, a radar reflector The SART also has an audio or visual indication of its correct operation and informs survivors when interrogated by the radar An audible beep is heard every 12 seconds when there are no radars in sight and every 2 seconds when interrogated by radar Carriage Requirement Passenger ship- at least 02 Cargo ship 500 GT and above- at least 02 Cargo ship 300 GT and above- at least 01 1 on each survival craft Battery Requirement In standby condition, operational for 96 hours In working condition, operational for 08 hours Battery should be replaced every 2 to 5 years Operable in temperature between -20 deg to 55 deg SART Test Procedure Self Test General Switch SART to test mode Hold SART in view of the radar antenna Check that visual indicator light operates Check that audible beeper operates Observe radar display and see if there are concentric circles on the PPI Check the battery expiry date Self Test Typical Remove SART from the bracket Insert the probe into the SART at 2 seconds interval; the lamp flashes and the beeper sounds Observe concentric circles on the X band radar In case of a false activation, switch the SART off immediately. Transmit a DSC safety alert on VHF Channel 70. Transmit a safety broadcast by RT on VHF Channel 16 to all stations indicating your ID and position and that you wish to cancel your false alert which was transmitted in error. AIS-SART 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 class-A position report. The position and time synchronization of the AIS-SART is derived from a built-in GNSS receiver GPS. 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 or a radar-SART Search and Rescue Transponder. SARTs find themselves useful in rescue operations involving aeroplanes or ships stranded by air and sea accidents. They are designed to survive the toughest conditions and stay active on elevated positions like on a pole so that they could cover a diverse range. Talking of heights, a SART transponder on an aeroplane could have a range of 30 to 40 miles. This helps to scrutinize a huge range and huge area. Looking at the facts, one can determine that SARTs are a marvel of human engineering, making them significant equipments on the ship venturing out in deep oceans.

Last Updated on October 11, 2022 by Amit AbhishekSearch And Rescue Transponder or SART in short is an integral part of ships GMDSS Global Maritime Distress and Safety System requirement under SOLAS after search and rescue transponder is a self-contained, waterproof transponder that when actuated during emergency reacts to the emission of a radar to send its current is both a vital and mandatory All GMDSS vessels up to 500 ton must carry one SART device on board ship, consists of 3 basic equipment a powerful battery, omni–directional radar receiver and its are designed to be compact and easy to use, are used / fitted on ships / vessels, life raft , boats and survival crafts. Once activated they can last for at least 96 mounted in a bulkhead bracket of the mother ship they can be carried in one hand to the liferaft when abandoning the ship and mounted on the canopy of the liferaft using the telescopic And Rescue Transponder SART Purpose, Requirement & UseThe main purpose of search and rescue transponder SART, is to receive and respond to the radar signals from aircraft or ship equipped with X-band radar with a response homing response or homing signal when seen from ships or aircraft radar will be indicated as a line of 12 dots n miles apart with the first dot shows the exact point of the SART sequence of dots on an X band-radar help the rescue team to easily recognize and locate the survival craft tracking the source of distress signal from the SART Global Maritime Distress and Safety System GMDSS , all passenger ships are required to carry at least 2 SART device. Similarly cargo ships up to 500 ton must carry one Cargo ships above 500 tons much carry two SART device. Similarly all life rafts much also include / have one SART, further there is also specific battery requirement for these example; the battery should be able to operate under most extreme conditions between -20°C to 55°C. Further, it should be able to operate continuously for 8 hrs and at-least 96 hrs on – General Features, Location & FunctioningMade of waterproof reinforced plastic it can withstand extreme weather condition and prolonged sun SART device is generally orange in color internationally Accepted standard , but a few times can also be seen in yellow is made as such it can float freely of the mother ship or survival operates in the 9 GHz 3 cm or X-band’ radar frequency band and does nor responds to or show on S-band is mounted / installed on the ship’s bulkhead near bridge using a fixed support or mounting can only be activated manually ON Position after break the security tab. Thus only respond when actuated under distress; the rotary switch will auto reset to off from test position once testing is advised but should be limited to very short period. Further, nearby ships should be informed in advance before device can either be used as portable device or mounted on survival activated the device will flash red light every 2 seconds under standby mode and will sound buzzer every 2 seconds with continues red light when actively activated it will send a distress signal that will show on the radar as 12 consecutive dots. As you approach the source the dots will start to get wider and form an Do You Activate SART On Ship?Search And Rescue Transponder SART is intended for use only in distress or emergency condition. But they are also to be inspected and tested 30 seconds during annual activate / operate the SART you first need to lift and remove it from the bulkhead bracket mounting point . Then break the safety or security tag away from the some design you need to pull front lanyard to break safety tab while other designs have different methods to do so check manual . Now to activate rotate the switch ring to ON are no operational differences between TEST and ON modes; it is just that when set to ON mode it will remain activated while you need to keep the rotating switch at TEST mode during the test once released when on Test Mode the rotating switch will automatically preset to OFF position. SART devices are tested annually for a period of 30 seconds to insure they are working generally check whether it responds to the radar and show as intended on the radar display on ship. Further we look out for intended sounds buzzer and signals red light for 30 it does not respond to the radar or do not flash red light every 2 seconds in standby mode / gives audible beeper each 2 seconds with red light when transponding the TEST is considered a Effective SART Range Maximum Detection range Effective RangeThe Search and Rescue Transponder SART is considered to be a line of sight device much like the VHF radio. Which means it won’t provide greater coverage beyond visible activation the SART will provide visible indication on radar screen of the searching ship or aircraft. When interrogated by a X-band radar placed at 15 m on ship, it should respond when interrogated up to 8 mounted at the height of 1 meter from sea level its effective range is just N-M TO N-M here N-M representing nautical mile when searched from sea when mounted at a height of meters it has an range of a little more than most vessels radars are mounted at more than 10 m or 15 m to be exact for merchant ships. This in fact increase the effective maximum detection range of these SART when interrogated by a X-band radar placed on an aircraft it has and effective range of more than 30 and Service RequirementsEnsure all crew members knows how it should be aware where to mount, how to mount and test the should be replaced every 2 to 5 a visual inspection of the device each long passage or once a month activate and test the SART for audio visual signals as well as intended results on radar sure it is placed in a way / operated that it is not accidentally the safety lock is in place and the seal is not activated accidentally your first response should be to switch off SART immediately and send DSC Safety Alert on VHF CH transmit a safety broadcast by RT on VHF Channel 16 to all stations indicating a mistake and you wish to cancel the false alert with your ID, ships info and case the SART fails in inspection or testing or is damaged send it back to the manufacturer or concerned authority most of the time authorized service agent .Location Errors Things To Consider There are inherent delay in SART responses. When interrogated by a X-band radar the SART sweeps through the entire X-band range for radar signal before locking onto the can understand it in a similar way your old car radio search the entire frequency band before locking onto the station sweeping of frequencies is required by default in SART operation because, all marine radars operate at a different frequencies in the X-band radar thus results in a delay when at larger distance of 6 to 8 nautical mile, such delay will show its location 150m off its actual position on radar Between EPIRB and SART?While most mariners know exactly what are the difference between EPIRB and SART is but many people do not. After all both are safety equipment used in distress assisting search and or Emergency Position Indicating Radio Beacons is a safety equipment that sends distress signal to the search and rescue coordinators via Cospas-Sarsat satellite basically sends distress beacon / signal containing encrypted identification number which holds information such as imo no, GPS data / ships location, ships name, date of event and mmsi no to the nearby shore stations with the help of satellite in the form of hexadecimal the other hand SART or Search And Rescue Transponder beams back radar signals when interrogated by a X-band radar, thus showing its location / position on the radar SART only works in visual range the higher the source of radar longer the detection range ; EPIRB can operate in beyond visual range sending distress signal under any data received on shore station is used in the initial rescue initiative while SART provide quick identification for nearby passing vessels or can be used at later stage of rescue SystemThe AIS-SART or Automatic Identification System Search And Rescue Transponder is a self contained radio device that transmit AIS messages containing location, static and safety information of the distressed AIS-SART system derive its data on ships position and time from its built in GNSS receiver GPS . AIS stations on receiving the AIS-SART signal results in a alert on the system Maritime Distress Safety System GMDSS require one or more search and resue device in the form of an traditional SART device or Automatic Identification System Search And Rescue Transponder AIS-SART.Unlike traditional SART device that works on radar frequency and can be seen on radar screen of any vessel or installation in range with X-Band radar, AIS-SART can only be detected by AIS AIS-SART is designed to be used / deployed in a similar way as any traditional SART device.
