Explanation

Please explain in the area below why an STA is necessary:
Orbital Sciences Corporation (Orbital) will launch and operate the OA-8 Cygnus spacecraft as part of the NASA Cargo Resupply Services (CRS) program. The Cygnus mission will include launch, orbit raising maneuvers, approach and berthing with the International Space Station (ISS), unberthing and departure from the ISS, orbit maneuvering, and destructive re-entry into the Earth’s atmosphere. Destructive re-entry is anticipated to be up to 14 days after separation from the ISS. During the period between ISS departure and re-entry, the Cygnus spacecraft will deploy cubesats. Spacecraft telemetry is transmitted during all phases of mission operations. An STA is requested at the direction of NASA and the NTIA due to the short duration of the mission and the need for close coordination within the necessary frequency bands. This STA is consistent with the FCC/NTIA policies developed during the STA application process for both the OA-6 and OA-7 Cygnus spacecrafts. See FCC File Number 1334-EX-ST-2015 and 1709-EX-ST2016 respectively.

Purpose of Operation

Please explain the purpose of operation:

Spacecraft telemetry links for monitoring of Cygnus spacecraft state of health. Telemetry links include: 1) S-Band Single Access (SSA) spread spectrum return link operation with NASA TDRSS 2) High data rate downlink operation with mission Ground Stations 3) A Cygnus to ISS link for proximity operations will be used during the mission. The transmitters supporting these links are described below: The Cygnus spacecraft configuration will comprise of two Quasonix radios operating at 2287.5 MHz in TDRSS SSA mode and it will also provide telemetry downlinks at 3 Mbps and 6 Mbps. The Quasonix radios have the same radio design as the radios used on the OA-6 and OA-7 missions. These radios will meet all STA parameters and conditions as compiled with the two previous CRS STA applications.
