3.1 The AIS should comprise:
-
.1 a communication processor, capable of operating
over a range of maritime frequencies, with an appropriate channel
selecting and switching method, in support of both short and long
range applications;
-
.2 a means of processing data from an electronic
position-fixing system which provides a resolution of one ten thousandth
of a minute of arc and uses the WGS-84 datum.;
-
.3 a means to automatically input data from other
sensors meeting the provisions as specified in paragraph 6.2;
-
.4 a means to input and retrieve data manually;

-
.2 receiving and processing information from other
sources, including that from a competent authority and from other
ships;
