17 October 2017 Attention: International Bureau of the Federal Communications Commission Subject: Request for Special Temporary Authority to Utilize New Transmit and Receive Frequencies for Tracking, Telemetry and Command (TT&C) services on Call Sign E990067 To Whom It May Concern, We have been instructed to file this application on behalf of Denali 20020 LLC, which seeks a Special Temporary Authority from the FCC to utilize new transmit and receive frequencies to provide TT&C services on Call Sign E990067. These services are intended to provide support to the SES-16/GovSat-1 satellite immediately following its launch and for a ten-day period thereafter during its transfer orbit as it travels to its final orbital position of 21.5E. Currently, the launch of the SES-16/GovSat-1 satellite is scheduled for the 16th of December 2017 (12/16/2017) with a secondary launch date on the 27th of December 2017 (12/27/2017). Denali 20020 LLC seeks a 90-day Special Temporary Authority from the FCC beginning on the 1st of December 2017 (12/01/2017) and ending on the 1st of March 2018 (03/01/2018). This will allow for any delays or launch date changes.
