Special Temporary Authority application - Explanation

Please explain in the area below why an STA is necessary:
A special temporary authority is requested for the REAL cubesat to conduct a six-month mission to conduct scientific research associated with understanding Earth's Van Allen radiation belts. Specifically, REAL will collect scientific data that will improve our understanding of the physical mechanisms responsible for scattering radiation belt electrons into the Earth's atmosphere, and will validate the design of a particle detector. Additionally, this university-based CubeSat mission will provide an educational opportunity for undergraduate and graduate students at three institutions.

Special Temporary Authority application - Initial values - Explanation

Please explain in the area below why an STA is necessary:
A special temporary authority is requested for the REAL cubesat to conduct a six-month mission to conduct scientific research associated with understanding Earth’s Van Allen radiation belts. Specifically, REAL will collect scientific data that will improve our understanding of the physical mechanisms responsible for scattering radiation belt electrons into the Earth’s atmosphere, and will validate the design of a particle detector. Additionally, this university-based CubeSat mission will provide an educational opportunity for undergraduate and graduate students at three institutions.

Special Temporary Authority application - Initial values - Purpose of Operation

Please explain the purpose of operation:
The demonstration will consist of a point-to-point downlink (in both RHCP and LHCP) from an S-band transmitter, on a 3U low earth orbit cubesat (referred to as REAL), to an existing 18.3 m earth station (ES) in S-band. The S-band ES is located in Laurel, Maryland, and is owned and operated by Johns Hopkins University Applied Physics Lab. The REAL satellite will also be equipped with a UHF transceiver for telecommand, tracking, and receipt of health data. The UHF-band radio will receive telecommand signals from and transmit telemetry to an earth station located in Bozeman, Montana that is owned and operated by Montana State University. All emissions will cease after the completion of the six-month demonstration. Please see Exhibit 1 for more information on the plan and objectives.
