Explanation
Please explain in the area below why an STA is necessary:
Raytheon Company (Raytheon) develops and tests a number of technologies for federal government customers. In the course of that development and testing, Raytheon often needs to test the new technologies to advance their development and see how they function. Raytheon’s engineering team has developed new rocket motors that require testing as quickly as possible to see if they can deliver performance that could be built into future Raytheon missile systems. The technology development requires this STA to enable the testing to continue.

Purpose of Operation
Please explain the purpose of operation:  Raytheon plans to characterize the performance of these new rocket motors by transmitting in-flight telemetry to the ground station. The testing will use off-the-shelf radio technology to see if the selected radios can be used for this purpose. The radios selected are small, lightweight, easily deployable, and affordable. These qualities make them ideal radio systems for transmitting the telemetry information needed to track the rocket and its performance in flight. Prior to flight of the rocket, the radio in the rocket will be calibrated with the radio on the ground. The operations will use one frequency for each flight from the frequency range requested in the application. The rocket will use one internal whip antenna attached to a radio on the circuit board in its section of the rocket. That antenna has no gain. The ground-based radios will transmit only during this set up time, using two Yagi antennas. When the rocket is in flight, it will transmit telemetry data to the ground station. During the rocket flight, the program will use Yagi antenna receivers on the ground to track the rocket and gather telemetry information. The rocket booster will be released from the payload at a designated point during the flight. At that point, the booster will release a parachute that lowers the booster safely to the ground. The payload will also release its own parachute for safe landing. The embedded GPS chip will use the radio to transmit the rocket location so that it can be recovered. The radio link will not control flight functions. The radio link will only be used for telemetry data.

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.
