Phone Number: 2062097468

Explanation

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.

Certification

Neither the applicant nor any other party to the application is subject to a denial of Federal benefits that includes FCC benefits pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. Section 862, because of a conviction for possession or distribution of a controlled substance. The applicant hereby waives any claim to the use of any particular frequency or electromagnetic spectrum as against the regulatory power of the United States because of the prvious use of the same, whether by license or otherwise, and requests authorization in accordance with this application. (See Section 304 of the Communications Act of 1934, as amended.) The applicant acknowledges that all statements made in this application and attached exhibits are considered material representations, and that all the exhibits part hereof and are incorporated herein as if set out in full in this application; undersigned certifies that all statements in this application are true, complete and correct to the best of his/her knowledge and belief and are made in good faith. Applicant certifies that construction of the station would NOT be an action which is likely to have a significant environmental effect. See the Commission's Rules, 47 CFR1.1301-1.1319.
