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

摘要

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.
