Exhibit 3 Supporting Information for Block 9 — Form 442 Page 3 This frequency authorization is requested to support the testing and development of video and control systems for the use on the Unmanned Powered Parafoil (UPP) an unmanned aerial vehicle. The requested frequencies include the uplink of aircraft control data and aircraft safety of flight data, and the downlink of telemetry, video and sensor data from the aircraft and the ground. The current communication system uses a 900Mhz data link to perform control and communications between the aircraft and the ground station. The system has a very short operating range due to the line of sight limitation of 900Mhz communications. in addition, the current system does not carry the capability to transmit video information from the aircraft to the ground. Several clients have requested the upgrade of the system to include a video downlink and an increased operating range between the aircraft and the ground station. This frequency authorization would allow Southwest Research Institute to investigate the operating range of the aircraft and provide a video link from the aircraft to the ground.
