Please explain in the area below why an STA is necessary:
This STA covers the operation of an experimental ground-based system for calibrating a space borne radar following deployment of the radar in space. This request is limited to transmissions of up to two minutes of a low power signal from the ground to the spacecraft. Use of the ground station is needed only for a few weeks during the commissioning of the radar in space. The spacecraft communications and radar operation are covered by a separate FCC filing (0228-EX-CN-2020). Previous STAs were for operation of this system in the San Francisco Bay Area. This STA covers temporary operation of the system at the Alaska Satellite Facility at the University of Alaska Fairbanks during the commissioning of the Capella-3 and Capella-4 satellites (expected launch date is Jan. 14).

Purpose of Operation
Please explain the purpose of operation:  The ground-based system will transmit a calibrated CW tone in the direction of the spacecraft as the spacecraft passes overhead. The tone will be tuned to the frequency of the radar and the power level precisely controlled. The ground station antenna will follow the spacecraft using a commercial off-the-shelf computer-controlled telescope mount. The power received by the spacecraft radar receiver will be used to radiometrically calibrate radar measurements.

Class of Station: MO
Nature of Service: Experimental

Requested Period of Operation
Operation Start Date: 01/14/2021
