Technical eXchange on AIS via Satellite II: Presentation to TEXAS II

Abstract

SOME ACCOMPLISHMENTS: Received and recorded high-fidelity AIS signals from space in real time. * Modified and assembled low-cost, portable, off-the-shelf ground station equipment to receive, digitize and store AIS signals from space. * Observed the emissions and interference in both AIS channels as well as the adjacent channels from space. * Recorded AIS emissions from open ocean and inland waterways during daytime and evening hours, and from the US west coast, east coast and the Middle East. * Determined the aggregate energy level of the AIS signals in space into an omni-directional antenna. * Validated and adjusted a space-based AIS payload. * Decoded up to 2,000 ship transmissions during a 10-minute satellite pass.
