The AIS-SART should be capable of transmitting messages
that indicate the position, static and safety information of
a unit in distress. The transmitted messages should be compatible
with existing AIS installations. The transmitted messages should
be recognized and displayed by assisting units in the reception range
of AIS-SART, and clearly distinguish the AIS-SART from an AIS installation.
2.1 The AIS-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;
-
.4 be capable of manual activation and deactivation;
provision for automatic activation may be included;
-
.5 be capable of withstanding without damage
drops from a height of 20 m into water;
-
.6 be watertight at a depth of 10 m for at least
5 min;
-
.7 maintain water tightness when subjected
to a thermal shock of 45°C under specified conditions of
immersion;
-
.8 be capable of floating (not necessarily
in an operating position) if it is not an integral part
of the survival craft;
-
.9 be equipped with buoyant lanyard, suitable
for use as a tether, if it is capable of floating;
-
.10 not be unduly affected by seawater or oil;
-
.11 be resistant to deterioration in prolonged
exposure to sunlight;
-
.12 be of a highly visible yellow/orange colour
on all surfaces where this will assist detection;
-
.13 have a smooth external construction to avoid
damaging the survival craft;
-
.14 be provided with an arrangement to bring the
AIS-SART antenna to a level of at least 1 metre above sea level,
together with illustrated instructions;
-
.15 be capable of transmitting with a reporting
interval of 1 minute or less;
-
.16 equipped with an internal position source
and be capable of transmitting its current position in each
message; and
-
.17 be capable of being tested for all functionalities
using specific test information.
2.2 The AIS-SART should have sufficient battery
capacity to operate for 96 h within a temperature range
of -20°C to +55°C, and to provide for testing of
the functions on the equipment. The AIS-SART should have
an unique identifier to ensure the integrity of the VHF
data link.
2.3 The AIS-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 +70°C.
2.4 The AIS-SARTs should be detectable at a range
of 5 nautical miles over water.
2.5 The AIS-SART should continue transmission
even if the position and time synchronization from the positioning
system is lost or fails.
2.6 The AIS-SART should transmit within 1 minute
of activation.
