Abstract
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.
