Explanation
Please explain in the area below why an STA is necessary:
Three Virginia universities have each have launched a 1U Cubesat. The satellites and ground stations are licensed as follows: University of VA, Cubesat Libertas, License 0263-EX-CM-2018 VA Tech, Cubesat Ceres VT, License 0252-EX-CN-2018 Old Dominion University, Aeternitas, License 0255-EX-CN-2018 (the subject of this STA) Also see attached exhibit for more information on the missions and licenses. They were carried to the International Space Station (ISS) on NG-11 resupply mission, launched April 17, 2019. They were deployed from the ISS on July 3. Since then, despite ongoing attempts, there has been no communication established between the ground stations and the satellites. The current concept of operation is for each university ground station to communicate with the cubesat from that university. We are requesting 3 separate Special Temporary Authorities, of which this is one, to enable each of the three university ground stations to transmit to each of the cubesats, and enable each of the cubesats to transmit to each of the ground stations. Also, we request Special Temporary Authority for the cubesats to communicate with the Wallops Flight Facility. It is thought that a larger antenna may have a better chance of communicating if performance of the cubesats is somehow impaired. All of this is expected to take place only for a limited time. One of the cubesats will deorbit in the next two months.

Purpose of Operation
Please explain the purpose of operation:  The purpose of operation is to troubleshoot communications systems on the 3 cubesats, restore function if possible, and send commands and receive data to carry out the experiments as was intended with the original Experimental license 0255-EX-CN-2018, during the next 6 months.

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.
