Explanation

Please explain in the area below why an STA is necessary: The Johns Hopkins University Applied Physics Laboratory (JHU/APL) with support from Morehead State University is working on an experiment that will use the MSU 21-m antenna to radiate a range of power levels for reception by the Mini-RF radar package aboard the Lunar Reconnaissance Orbiter (LRO). This signal, of known power level, will be used to establish a baseline amplitude so that a received power level at the Mini-RF Antenna can be established. We estimate on-air activities should not exceed a three month period. A previous measurement was made, but the data were not conclusive, so JHU/APL would like to repeat the experiment.

Purpose of Operation

Please explain the purpose of operation:

A range of power levels that were injected into the LRO hosted Mini-RF receiver channels prior to flight did not show the imbalance that is now observed during the Earth-pointing measurements. It is possible that some element of the receiver chain has changed behavior during flight. It is therefore of interest to vary the power flux density at the antenna across a range of levels spanning that present during lunar backscatter and that present during Earth-pointing. Obtaining that information is the purpose of the testing.

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.
