Ship Reporting Capacity - the system should be able to handle a minimum of 2000 reports per min to adequately provide for all operational scenarios envisioned.
6.3 Security
A security mechanism should be provided to detect disabling and to prevent unauthorised alteration of input or transmitted data. To protect the unauthorized dissemenation of data, the IMO guidelines (Guidelines and Criteria for Ship Reporting Systems*) should be followed.
7. Permissible initialization period
The installation should be operational within 2 min of switching on.
8 Power supply
The AIS and associated sensors should be powered from the ship's main source of electrical energey. In addition, it should be possible to operate the AIS and associated sensors from an alternative source of electrical energy.
9 Technical characteristics
The technical characteristics of the AIS such as variable transmitter output power, operating frequencies (dedicated internationally and selected regionally), modulation, and antenna system should comply with the appropriate ITU-R Recommendations.
