7.7.3 Third party data feeds may also be required including:


n AIS data; n Weather forecast data; n Tidal almanac data.


7.8 Data interpretation 7.8.1 The MASS shall have at least one of the following:


n The ability to interpret sensor data on board in a timely manner with regard to its impact on MASS safety and performance and to execute its responsibilities in accordance with COLREG and international law;


n The ability to transmit sensor data in a timely manner to an off-board system or human operator who can interpret the data with regard to its impact on MASS safety and performance; and to receive appropriate commands in response, in a timely manner.


7.8.2 Sufficient data from the sensors (internal and/or external) shall be made available in a timely manner to a System which is capable of exerting control over the MASS, bringing it to a safe haven or away from a danger area when deemed necessary. The System, in this context, must include at least one of:


n A human operator using a Control Station (LoC L1-L3); n An on-board or remote automatic system (LoC L3-L5); n A distributed system comprising on-board and off-board elements, which may or may not include a human operator or supervisor, with appropriate communication links between them.


7.8.3 In order to interpret sensor data in regard to its impact on MASS performance, the System shall be capable of determining or forecasting, by means of algorithms or data, as necessary to ensure safe operation:


n Safe operating limits for sensor data where applicable; n Permitted geographic area(s) and time window(s) for MASS operation; n Expected water depth in relation to geographic position and time; n Expected water current speed and direction in relation to geographic position and time.


7.8.4 Where applicable and deemed necessary the MASS is to be capable of de-conflicting the data presented by different sources.


7.8.5 The System shall be capable of taking operational decisions in accordance with the sensor data interpretation, in order to maintain the safety and integrity of the MASS, surrounding objects and personnel, and to pursue its mission subject to those safety considerations.


7.9 Control


7.9.1 The MASS shall have the ability to be controlled by a Control System which may be an on-board, off-board system or human operator, or a distributed system involving one or more of these elements. Control is typically a com- bination of high level and low level functions and behaviours, which may be implemented in separate modules, such as the following examples:
