First, attached is a data file which contains updated GXT files. These files have been modified from their previous submission in order to correct the header information so as to align it with the pending modification. Second, in regards to the saturation flux density (SFD) for receive beams oriented towards gateways, the values will range from -78 to -98 dBW/m2 when automatic level control is not used. For receive beams oriented towards the user terminals, the SFD will range from -94 to -74 dBW/m2 when automatic level control is not used. For cases when the automatic level control system is enabled, there is no saturated flux density. Finally, the maximum EIRP density for beams oriented towards either gateways or user terminals is 41 dBW/MHz. The EIRP density for telemetry is of 17 dBW/MHz.

Please let me know if you have any questions or need additional information. Best regards Steven Doiron Senior Director, Regulatory Affairs Hughes Network Systems Attachments: (1) cc. Jose Albuquerque, Stephen Duall, Kal Krautkramer, Kathyrn Medley, Clay Decell
