- Applicant 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.

Special Temporary Authority application - Explanation
- Please explain in the area below why an STA is necessary:
- We are producing the 2nd Annual National Drone Racing Championships to be held on Governors Island, New York City. The aircraft use Video transmitters operating in the 5.8ghz spectrum. The event is an official sanctioned amateur event by the Academy of Model Aeronautics (AMA). We have the approval and permits from the Governors Island Trust. We have submitted our rules and risk management plans to the FAA, and they are comfortable with the event from an airspace perspective. We are asking for an Experimental Special Temporary Authority for use of video transmission technologies within the 5.8Ghz spectrum. We would like to use these frequencies: Primary: 5658, 5695, 5732, 5769, 5806, 5843, 5880, 5917 Secondary: 5473, 5510, 5547, 5584, 5621 Currently these frequencies are already allocated for use, but the power output under FCC Part 15 is insufficient for safe and effective use. We would like to increase the power from 25mw up to 250mw to provide stable video signal for the pilots. The Drone Races use “First Person View” (FPV) on a small quadcopter airframe, using a 5.8Ghz Video Transmitter. We would like to use these frequencies: Primary: 5658, 5695, 5732, 5769, 5806, 5843, 5880, 5917 Secondary: 5473, 5510, 5547, 5584, 5621 Currently these frequencies are already allocated for use, but the power output under FCC Part 15 is insufficient for safe and effective use. We would like to increase the power to 250mw or 600mw to provide stable video signal for the pilots. Furthermore, we would like to have an experimental license held directly by Flying Grounds and or the State of California State Fair in order to provide transmitters to the pilots directly so that each pilot does not have to obtain a HAM license.

Special Temporary Authority application - Initial values - Purpose of Operation
- Please explain the purpose of operation:
- Amateur RC model quadcopter aircraft flying and racing using air to ground 5.8ghz video transmission systems. We would like to experiment with a new a approach to large scale group FPV (first person view) quadcopter flying and racing. Currently the problem is most FPV pilots do not hold HAM licenses, and the available frequencies are restrictive to only having 3-4 pilots in the air at one time. We also have a mismatch of transmitter powers, and varying types of antennas. This creates a substantial safety issue for FPV flying due to serious multi-pathing issues. The system we are proposing is to provide diversity receivers with directional antennas pointing specifically at the field. We are supplying each racer with a video transmitter pre-assigned to a frequency and power output. With each transmitter at the same power output (between 25mw and 250mw), we can space each racer 37Mhz apart, and using Right-hand and Left-hand polarized antennas, we can get up to 8-12 racers in the air at one time, safely and efficiently. The Frequencies are 12Mhz off the top and bottom of the HAM frequencies, so other than the power output issue, most of the system is already compliant, and is of low enough power not to impact any other near by transmission operations outside of Governors Island. The intended outcome of this system is to help define a better more organized approach to any organization wishing to hold FPV/Drone races in the future. This would include any official AMA races and the numerous drone racing leagues that are rapidly appearing all over the US. Even the FAA is now considering FPV Drone races at their airshows, and this would be a great case study to provide better information for these types of races. It is specifically intended to help define appropriate and acceptable use for organizations, and would not be used by an individual amateur/hobbyist radio controlled pilot (with or without a HAM license).
