IBFS_SESSTAINTR201902604_1747910

REQUEST FOR SPECIAL TEMPORARY AUTHORITY By this application, SES Americom, Inc. (“SES”) respectfully requests special temporary authority (“STA”) (extension of the STA granted until 08/05/2019) for a period of 180 days, starting on 08/06/2019, to operate the station with call sign #E170197, in the Ext. Ku- band frequency on a non-interference basis as the license application to operate the antenna in the frequency has been in pending since 9/20/2017. The carriers in the frequency band will be operated within the EIRP & EIRP density limit as specified in the interference study that was submitted with the license application. The antenna will communicate with SES-14 (call sign S2974), Brazil-licensed satellite that is on the Commission’s Permitted Space Station List. The technical details of the proposed operations are provided below, and the antenna will be operated in compliance with the Commission’s radiation hazard limits. Grant of the requested authority will avoid numerous filings of STAs to allow SES to continue the services offered with the antenna.
