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.

Methods and systems for enhancing the detectability of electronic tracking messages are provided. Transmitters apply error protection encoding to the payload portion of messages to be transmitted. 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. Candidate messages are identified and the error protection encoding decoded to recover messages.

Methods and systems for enhanced detection of electronic tracking messages

Methods and systems for enhancing the detectability of maritime e-Navigation messages are provided. Transmitters apply error protection encoding to the payload portion of messages to be transmitted, which are wrapped in a standard e-Navigation message format such as that used by the Automatic Identification System. 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. Candidate messages are identified and the error protection encoding decoded to recover messages.

A hardened voyage data recorder includes two subsystems: a removable non-volatile memory and a base containing electronics and firmware for communicating with data sensing systems and for accessing the memory. According to the invention, the memory is protected in a 'boiler' and the electronics includes an ETHERNET interface for connecting to shipboard data acquisition devices. The firmware is preferably configured via web pages. A communications protocol for communicating with the recorder is also disclosed.
