9 GHz Radar – is required on any vessel of 300 GT and over.
3 GHz Radar – to be fitted as the second radar, which is required on ships of 3000 GT and over unless the Administration considers it appropriate to carry a second 9 GHz Radar. The two radars must be functionally independent of each other. The MCA will require a reasoned case for why a 3 GHz radar cannot be carried.
EPA – To be incorporated in Radar equipment on ships of 300 gt. and over, but less than 500 GT.
ATA – To be incorporated in Radar equipment on ships of 500 GT. and over (replacing the requirement for an EPA)
On ships of 3000 GT and over the second radar must also be equipped with an ATA. The two ATAs must be functionally independent of each other.
ARPA – To be incorporated in one Radar equipment on ships of 10000 GT and over. The second unit must incorporate ATA if not ARPA.
Summary of minimum Radar requirements:
Automatic Tracking Aid (ATA) :-
ATA equipment enables manual acquisition and automatic tracking and display of at least 10 targets.
Electronic Plotting Aid (EPA):-
EPA equipment enables electronic plotting of at least 10 targets, but without automatic tracking.
