Abstract
Systems and methods for vessel position reporting and monitoring. Methods and systems for augmenting e-Navigation messages to provide ancillary information, such as a history of previous vessel positions. A compact representation is provided, in which transmitters may select among a plurality of possible position layouts to provide a compact representation. Transmitted messages are received by a satellite or other surveillance platform employing a compatible radio frequency receiver to collect message signals over a large area or great distance.
Claims27
A method of transmitting a message that identifies a geographical position, the method comprising:
- encoding a track history to generate an encoded track history;
- generating the message comprising the encoded track history;
- and
- transmitting the message.
A method of processing a message, the method comprising:
- receiving a first message, the first message comprising a track history, wherein each of the track history points is determined with reference to a predetermined point layout defined in the first message, the predetermined point layout having a plurality of predefined point positions;
- and
- processing the first message to obtain the track history.
An apparatus for transmitting a message that identifies a geographical position, the apparatus comprising:
- a memory that stores a track history;
- a processor configured to:
- encode the track history to generate an encoded track history;
- generate the message comprising the encoded track history;
- and
- a transmitter that transmits the message.
A non-transitory computer readable medium storing computer executable instructions, the instructions, when executed by a computer processor, for causing the computer processor to perform a method of transmitting a message that identifies a geographical position, the method comprising:
- encoding a track history to generate an encoded track history;
- generating the message comprising the encoded track history;
- and
- controlling a transmitter to transmit the message.
