Explanation

Please explain in the area below why an STA is necessary: SNC currently performing on a U.S. Government contract for the U.S. Army. Part of that contract requires us to test a receive only system located on an aircraft during flight. To perform testing we need to generate approximately 400 frequencies from a ground station from 20 Mhz to 1.0 Ghz. 186 of these frequencies lay within the band of 30 Mhz to 186 Mhz. The Transmit duty cycle of these frequencies is 10 milliseconds on and 25 milliseconds off. We will transmit 8 frequencies at a time with a CW tone until all frequencies have been transmitted then we would repeat the list again for a total of 4 hours one day and four hours the next day (2 day test) for one aircraft. I need to test 7 total aircraft over the next 24 months. The first aircraft is expected to test in mid- November 2019. We expect over the next two years to have perform this test a total of 14 times. Power level is expected to be 10W average. We would have a dedicated flight path for the aircraft and will be using a directional antenna for radiation.

Purpose of Operation

Please explain the purpose of operation:

The purpose of this operation is to collect data in an airborne environment that will be used to calibrate a special mission system that is used for geolocation purposes.

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.
