What causes the SART to begin a transmission?
When activated manually, it begins radiating immediately.
It is either manually or water activated before radiating.
After being activated the SART responds to radar interrogation
It begins radiating only when keyed by the operator.
How does the searching vessel's radar interrogate a survival craft SART?
Activate the IFF interrogation system.
The SART responds automatically when it detects the search craft or other vessels' X-Band radar signal.
Maintain watch on VHF-FM Ch-70 for the SART's unique identifier.
The SART responds automatically when it detects the search craft or other vessel's 3.5 GHz radar signal.
What does a SART signal sound or look like?
It transmits "SOS" and the vessel's name and position in slow speed Morse Code
It will appear on a radar unit's PPI as a line of dots radiating outward with the innermost dot indicating the
SART's position.
It will appear on a radar unit's PPI as a line of dots radiating outward with the outermost dot indicating the
SART's position.
None of the above.
How can rescue personnel detect that a SART is transmitting in the immediate vicinity?
The SART's dots on the PPI will begin arcing and eventually become concentric circles
The DSC unit will react to the SART's signal and respond with the two-tone auto alarm.
The SART can provide an approximate location to within a two nautical mile radius, per IMO standards.
The SART signal appears as a target which comes and goes; the effect of heavy swells on a SART.
What signal is detected as originating from an SART?
The Morse code distress series S-O-S repeated three times followed by DE and the vessel's call sign.
line of dots on a radar screen outward from the SART's position along its line of bearing.
A line of dots on a radar screen inward from the SART's position to its own ship along its line of bearing.
None of these.
How can vessel personnel detect the operation of a SART in its vicinity?
A unique radar signal consisting of a 12 dots radiating outward from a SART's position along its line of
bearing.
A unique two-tone "warbling" signal heard on VHF-FM Ch-70.
A unique two-tone alarm signal heard upon the automatic un-muting of the 2182 kHz radiotelephone
automatic watch receiver.
The SART signal appears as a target which comes and goes; the effect of heavy swells on an SART.
How should the signal from a Search And Rescue Radar Transponder appear on a radar display?
A series of dashes
A series of spirals all originating from the range and bearing of the SART.
A series of 12 equally spaced dots.
A series of twenty dashes.
In which frequency band does a search and rescue transponder operate?
3 GHz
9 GHz
S-band
406 MHz
Which of the following would most likely prevent a SART's signal from being detected?
Signal absorption by the ionosphere
Heavy sea swells
The rescue personnel were monitoring the 10-CM radar.
The rescue personnel were monitoring the 3-CM radar
Which statement is NOT true regarding the SART?
Responds to interrogations by a vessel's X-Band radar
Transmits on the 9 GHz band reserved for navigational radar
Operates in conjunction with a vessel's S-Band radar.
Transmits a distinctive code for easy recognition.
Which statement is true regarding the SART required for GMDSS compliance?
This is a performance monitor attached to at least one X-band navigational radar system
This is a 9 GHz transponder capable of being received by vessel's X-band navigational radar system
This is a 9 GHz transponder capable of being received by another vessel's S-band navigational radar system.
This is a performance monitor attached to at least one X-band navigational radar system.
Which statement is NOT true regarding the SART?
Responds to interrogations by a vessel's X-Band radar.
This is a 6 GHz transponder capable of being received by a vessel's X-band navigational radar system.
This is a 9 GHz transponder capable of being received by another vessel's X-band navigational radar system
Transmits a distinctive signal for easy recognition
A SART's signal cannot be detected:
In poor visibility or at night
In heavy seas
By a search vessel's 10 cm Radar
By a search vessel's 3 cm Radar.
Which is a function of a satellite under COSPAS-SARSAT using satellite EPIRBs?
Vessel information recovered from the digital encoded message provided by the satellite EPIRB.
Doppler shift of EPIRB signal is measured
Information received from EPIRBs are time-tagged and transmitted to any Local User Terminal in the
satellite's view.
All of these.
Which of the following satellite systems is of particular importance to search and rescue missions under
GMDSS?
COSPAS/SARSAT.
AMSAT
NASA/Arienne.
COMSAT.
Which of the following statements concerning COSPAS-SARSAT is true?
EPIRBs are units that are used as alerting devices.
These are satellites in a low-earth polar orbit that detect EPIRB beacons on 406 MHz and relay the
information to an earth-side Local User Terminal (LUT).
The Doppler frequency measurement concept is used to determine the EPIRB's location
All of the above.
Which of the following statements concerning satellite EPIRBs is true?
Once activated, these EPIRBs transmit a signal for use in identifying the vessel and for determining the
position of the beacon.
The coded signal identifies the nature of the distress situation
The coded signal only identifies the vessel's name and port of registry
If the GMDSS Radio Operator does not program the EPIRB, it will transmit default information such as the
follow-on communications frequency and mode.
Which of the following EPIRBs is most likely to be used to transmit a distress alert signal?
S-Band EPIRBs
406 MHz EPIRBs
Class A EPIRBs.
121.5/243 MHz EPIRBs.
