Status of AIS Frequencies Nationally and Internationally: Improving Satellite Detection of AIS

Abstract

Where things stand, where we're headed, and where do we want to go? * Both AIS frequencies were originally used for other purposes. What other purposes? How does that legacy affect us now? * Most maritime frequencies, AIS included, are shared with other users. Where? How many? What power? What duty cycle? Can we live with them? * AIS transmissions were never designed for satellite detection. How will growing congestion of the band (e.g. Class B, encrypted STEDS, Search & Rescue, Aids to navigation) affect satellite detection? Is this a problem needing to be addressed? If so, how? * Where do we need to go? Clear existing AIS frequencies from other uses? Dedicated satellite frequency? Will other Administrations support or oppose these initiatives? Is good engineering practices instead of a regulatory solution sufficient?
