The SART should be capable of indicating the location of
a unit in distress on the assisting units radars by means of a series
of equally spaced dots (see Resolution A.530(13)).
-
2.1 The SART should:
-
.1 be capable of being easily activated by unskilled
personnel;
-
.2 be fitted with means to prevent inadvertent
activation;
-
.3 be equipped with a means which is either visual
or audible, or both visual and audible, to indicate correct operation
and to alert survivors to the fact that a radar has triggered the
SART;
-
.4 be capable of manual activation and deactivation;
provision for automatic activation may be included;footnote
-
.5 be provided with an indication of the stand-by
condition;
-
.6 be capable of withstanding without damage drops
from a height of 20 m into water;
-
.7 be watertight at a depth of 10 m for at least
5 min;
-
.8 maintain watertightness when subjected to a
thermal shock of 45°C under specified conditions of immersion;
-
.9 be capable of floating if it is not an integral
part of the survival craft;
-
.10 be equipped with buoyant lanyard, suitable
for use as a tether, if it is capable of floating;
-
.11 not be unduly affected by seawater or oil;
-
.12 be resistant to deterioration in prolonged
exposure to sunlight;
-
.13 be of a highly visible yellow/orange colour
on all surfaces where this will assist detection;
-
.14 have a smooth external construction to avoid
damaging the survival craft; and
-
.15 be provided with a pole or other arrangement
compatible with the antenna pocket in a survival craft in order to
comply with 2.4, together with illustrated instructions.
-
2.2 The SART should have sufficient battery capacity
to operate in the stand-by condition for 96 h and, in addition, following
the stand-by period, to provide transponder transmissions for 8 h
when being continuously interrogated with a pulse repetition frequency
of 1 kHz.
-
2.3 The SART should be so designed as to be able
to operate under ambient temperatures of -20°C to +55°C. It
should not be damaged in stowage throughout the temperature range
of -30°C to +65°C.
-
2.4 The height of the installed SART antenna should
be at least 1 m above sea-level.
-
2.5 Horizontal polarization or circular polarization
should be used for transmission and reception.
-
2.6 The SART should operate correctly when interrogated
at a distance of up to at least 5 nautical miles by a navigational
radar complying with resolutions A.477(XII) and A.222(VII), with an
antenna height of 15 m. It should also operate correctly when interrogated
at a distance of up to 30 nautical miles by an airborne radar with
at least 10 kW peak output power at a height of 3,000 ft.
