Inmarsat Plan for Protecting Authorized Operators Using C-band Frequencies within +/- 6 Degrees of the Inmarsat-4F1 or Inmarsat-4F3 Spacecraft This report is submitted in response to the Commission’s request for a comprehensive plan detailing how Inmarsat will protect other authorized operators using C-band frequencies within +/- 6 degrees of the Inmarsat-4F1 or Inmarsat-4F3 spacecraft, which are operated using Inmarsat’s earth station facilities located at Paumalu, Hawaii. Inmarsat has completed conventional C-band frequency coordination with all U.S. satellite networks operating under more senior ITU filings within +/- 6 degrees of Inmarsat-4F1 (143.5 degrees E.L.) and Inmarsat-4F3 (97.65 degrees W.L.).1 In the frequency coordination agreements, certain limits were agreed to protect adjacent U.S. satellite networks. Inmarsat currently operates Inmarsat-4F1 and 4F3 frequency carriers within the following agreed conventional C-band limits: Earth Station Location: Paumalu, Hawaii, U.S. Earth Station Antenna Diameter: Two 16m antennas (Call Sign E080059) and One 19m antenna (Call Sign KA25) Uplink transmit power: 9.5 dBW Downlink EIRP: 10.5 dBW Below is a list of U.S. satellite networks with which coordination is completed for each of the Inmarsat-4F1 and 4F3 spacecraft: Inmarsat-4F1 (143.5 degrees E.L.) Orbital location (deg. E.L.) Operator 139 Loral 149 Intelsat 150 Unassigned / FCC 151.5 Unassigned / FCC 1 Inmarsat-4F3 is notified at the ITU as INMARSAT-4 98W at 98 degrees W.L. All frequency coordination agreements with U.S. satellite networks have been taken into account for operations at 97.65 degrees W.L. DC\1257982.1
