             Applications of Iridium Satellite LLC and Iridium Carrier Services LLC
             for blanket earth station AMS(R)S authority
Dear Ms. Dortch:

In the above-referenced applications, Iridium Satellite LLC and Iridium Carrier
Services LLC (collectively, “Iridium”) are seeking blanket earth station license
modifications that would authorize using earth stations on aircraft to provide
AMS(R)S. Iridium hereby clarifies certain elements of its applications.

Terminal types for which AMS(R)S authority is sought. Each of Iridium’s
blanket earth station licenses (E960132 and E960622) identifies three antenna
types. Iridium seeks AMS(R)S authority only for the first antenna type shown
in each license.

Areas within which AMS(R)S will be provided: Iridium’s request for
AMS(R)S authority is limited, both within the United States and outside the
United States, to oceanic, polar, and remote regions.

Providing AMS(R)S only within authorized areas: The aeronautical systems
on aircraft that are equipped with Iridium’s AMS(R)S terminals are designed to
attempt communication first with the terrestrial network. The aeronautical


systems will not attempt to communicate with Iridium’s satellite network
unless contact cannot be made with the terrestrial network.

Obtaining authority from relevant airspace administrators. Iridium has been
securing AMS(R)S authority on a country-by-country basis from relevant
airspace administrators. Iridium already has AMS(R)S authority from the
Federal Aviation Administration, which is the airspace administrator for the
United States, and from all other airspace administrators that, together with the
FAA, have jurisdiction over all oceanic, polar, and remote regions in which
Iridium currently has plans for providing AMS(R)S.

Implementation of priority and preemption. Each Iridium terminal that will
be used to provide AMS(R)S has an identifier that enables Iridium’s network to
identify the terminal as supporting AMS(R)S transmissions and to provide
appropriate levels of priority and preemption for the transmissions.

      Please direct any questions concerning this matter to the undersigned.
                                                Sincerely,

                                                /s/Donna Bethea Murphy
                                                Vice President, Regulatory
                                                Engineering
