Message can be routed to “all stations”, to an individual station or to a group of stations, using their Maritime Mobile Selective-call Identify code (MMSI):Distress messages are automatically broadcast to “All stations”. In addition to the MMSI of source and destination stations, information can be conveyed in the DSC message:For example, to aid the Rescue Service, the DSC Distress alert message is configured to contain the following: A\Ship‟s identify (the nine digit MMSI) B\Time. C\ Nature of distress (in the form of standard code) D\Ship‟s position.Where fitted ship‟s officers should ensure they are fully conversant with the procedure for entering the necessary information into DSC equipment:At sea, unless provided automatically from a navigation system, ship‟s position should be update at least once during each watch period.1. At sea, if DSC equipment can‟t get ship‟s position message from a navigation system automatically, then the position message should be renewed _______.A. .at least every 4 hours:B. at least every 8 hoursC.at least every 12 hours:D. at least every 24 hours.2. According to the message, distress message can be received by _______.A. all stations:B. coast stations.C. ship stations:D. group of specified stations3. Each DSC “packet” have _______ priority(priorities)A. 1B. 2C. 3D. 44. Which of the following statement is not true?A. A DSC message has a MMSI of source station.B. A DSC message has a MMSI of destination station.C. A DSC message has a name of source station.D. A DSC message also has other information for sending rounD.Passage2.The NA VTEX receiver is a Narrow Band Direct Printing (NBDP) device operating on the frequency 518Khz, (some equipment can also operate on 490Khz and 4209.5Khz), and is a vital part of the Global Maritime Distress and Safety System (GMDSS).It is automatically receives Maritime Safety Information such as Radio Navigational Warnings, Storm/Gale Warnings, Meteorological Forecasts, Piracy Warnings, Distress Alert etc.The information received is printed on the receiver‟s own paper recorder roll:Each message begins with starts of message function (ZCZC) followed by a space then four B characters:The First, (B1), identifies the station beingreceived, the second, (B2), identifies the subject i.e:Navigational Warning, Met Forecast etc, and the third and fourth, (B3+B4), form the consecutive number of the message from that station:This followed by the text of the message and ends with an end of message function (NNNN).The NA VTEX system broadcasts COASTAL WARNING which cover the area from the fairway buoy out to 250 nautical miles from the transmitter, the transmission from some transmitters can be received out to 400 nautical miles and even further in unusual propagation conditions.1.

NBDP should not be used for the distress traffic.Passage5.The IMO also introduced digital selective calling (DSC) on VHF, MF and HF maritime radios as part of the GMDSS system: DSC is primarily intended to initiate ship/ship, ship/shore, and shore/ship radiotelephone and MF/HF radiotelex calls: DSC calls can also be made to individual ships or groups of ships: DSC distress alerts, which consist of a preformatted distress message, are used initiate emergency communications with ships and rescue coordination centers: When fully implemented, DSC will eliminate the need for persons on a ship's bridge or on shore to continuously guard radio receivers on voice radio channels, including VHF channel 16 (156:8 MHz) and 2182 kHz now used for distress, safety and calling: A listening watch aboard GMDSS-equipped ships on 2182 kHz ended on 1 February 1999, and on VHF channel 16 is scheduled to end on 1 February 2005: We urge that the DSC-equipped VHF and MF/HF radios beexternally connected to a satellite navigation receiver: That connection will ensure accurate location information is sent to a rescue coordination center if a distress alert is ever transmitteD. FCC regulations actually require that ship's position be manually entered into the radio every four hours on ships required to carry GMDSS equipment, while that ship is underway (47 CFR 80:1073): Once SOLAS ships are allowed to disband watch-keeping on VHF and MF radiotelephone channels, other ships are going to need DSC-equipped radios to contact these ships, particularly in a passing situation, especially when outside U:S: waters: We believe VHF, MF and HF radiotelephone equipment carried on ships should include a DSC capability as a matter of safety: To achieve this, the FCC requires that all new VHF and MF/HF maritime radiotelephones type accepted after June 1999 to have at least a basic DSC capability: VHF digital selective calling also has other capabilities beyond those required for the GMDSS: The Coast Guard uses this system to track vessels in Prince William Sound, Alaska, V essel Traffic Service: IMO and the USCG also plan to require ships carry a Universal Automatic Identification System, which will be DSC-compatible: Countries having a GMDSS A1 Area will be able to identify and track AIS(自动识别系统)-equipped vessels in its waters without any additional radio equipment:1. Which of the following is the best answering?A. Only VHF equipment can used DSC.B. Only MF equipment can used DSCC. Only HF equipment can used DSC.D. DSC will use on VHF, MF and HF equipment2. According to this message, which of the following is wrongA. When fully implemented, for persons to continuously guard will eliminateB. DSC is used for watchingC. DSC is only used for watching:D. DSC is used to initiate emergency communication:3. According to this message, the watch-keeping of VHF CH16 will be ended _______:A. on 1 February 1999:B. on 1 February 2005:C. on 1 February 2000:D. on 1 February 2010:4. The writer intends that the VHF/MF/HF radio equipment _______:A. should have its own satellite navigator;B. have nothing to do with the satellite navigation system;C. should be connected to a satellite navigator:D. should change the ship‟s position manually every hours:5.

The meaning of word “radios” in the passage is :A. radio equipmentsB. radio wavesC. radio programsD. no meaningPassage6.Satellite systems operated by the International Mobile Satellite Organization (Inmarsat), are also important elements of the GMDSS: Three types of Inmarsat ship earth station terminals are recognized by the GMDSS: the Inmarsat A, B and C. The Inmarsat A and B, an updated version of the A, provide ship/shore, ship/ship and shore/ship telephone, telex and high-speed data services, including a distress priority telephone and telex service to and from rescue coordination centers: The Inmarsat C provides ship/shore, shore/ship and ship/ship store-and-forward data and telex messaging, the capability for sending preformatted distress messages to a rescue coordination center, and the SafetyNET service: The Inmarsat C SafetyNET service is a satellite-based worldwide maritime safety information broadcast service of high seas weather warnings, NA V AREA navigational warnings, radionavigation warnings, ice reports and warnings generated by the USCG-conducted International Ice Patrol, and other similar information not provided by NA VTEX: SafetyNET works similarly to NA VTEX in areas outside NA VTEX coverage: Inmarsat C equipment is relatively small and lightweight, and costs much less than an Inmarsat A or B. Inmarsat A and B ship earth stations require relatively large gyro-stabilized antennas; the antenna size of the Inmarsat C is much smaller: Inmarsat also operates an EPIRB system, the Inmarsat L, which is similar to that operated by COSPAS-SARSA T: Under a cooperative agreement with the National Oceanic and Atmospheric Administration (NOAA), combined meteorological observations and AMVER reports can now be sent to both the USCG AMVER Center, and NOAA, using an Inmarsat C ship earth earth station, at no charge: There is also no charge to register for this service and to receive the necessary Inmarsat C software: For more information, see the NOAA Shipboard Environmental (data) Acquisition System, or SEAS: We strongly urge that Inmarsat C equipment have an integral satellite navigation receiver, or be externally connected to a satellite navigation receiver: That connection will ensure accurate location information to be sent to a rescue coordination center if a distress alert is ever transmitteD.1. According to the passage, which type of Inmarsat SES terminals are approved by the GMDSS?A. INMARSA T-C;B. INMARSA T-M;C. INMARSA T MINI-M;D. INMARSA T-P2. The writer suggests that INMARSA T-C ship earth stations ______A. should have an satellite navigator;B. should be connected to a satellite navigation receiverC. A & BD. A or B3. The SafetyNET (satellite-based worldwide maritime safety information broadcast service) service is provided by _____________A. INMARSA T-AsystemB. INMARSA T-B systemC. INMARSA T-C systemD. INMARSA T-M system4. Which ship earth station does not requires relatively large gyro-stabilized antenna?A. INMARSA T-AB. INMARSA T-BC. INMARSA T-CD. Both A & B5. The meaning of phrase “store-and-forward” in the passage isA. first memorize, then relayB. memorizing messageC. directly send messageD. store a file6. INMARSA T-L isA. INMARSA T-C systemB. INMARSA T-BC. EPIRB system of INMARSA TD. COSPAS-SARSA T7. According to the passage, which of the following is not true?A. a meteorological observation can be transmited to NOAA with Inmarsat-C SES at free of chargeB. A AMVER reports can be transmited to the USCG AMVER Center at chargeC. It is no charge to register for AMVER serviceD. It is no charge to receive Inmarsat-C softwarePassage7.The GMDSS installation on ships include one or more search and rescue radar transponders (SART), devices which are used to locate survival craft or distressed vessels by creating a series of dots on a rescuing ship's 3 cm radar display: The detection range between these devices and ships, dependent upon the height of the ship's radar mast and the height of the SART, is normally about eight nautical miles: Note that a marine radar may not detect a SART even within this distance, if the radar settings are not optimized for SART detection1. Which statement is true according to the passage?A. SART can send alert signals to RCC through INMARSA T system;B. SART can send alert signals to RCC through COSPAS-SARSA T system;C. SART can send alert signals to RCC through VHF/HF/MF communication system;D. SART is used to locate survival craft or distressed vessels2. The detected distance of SART is determined by_________A. The position of the SARTB. The frequency of the marine radarC. The height of the radar antenna and the SARTD. The frequency of the SART3. If the radar settings are not optimized for SART detection，maybeA. can not see returns of SART on radar screenB. can see returns of SART on radar screenC. affect function of SARTD. be independent of radar detectingPassage8.Radar should not be regarded as more than an aid to the detection of other vessel, and collisions in poor visibility can be averted for certain only if the information provided by the radar set is correctly interpreted。
