Explanation

Please explain in the area below why an STA is necessary: This request for Special Temporary Authority (STA) is submitted pursuant to 47 CFR 5.61 to request authorization to perform performance evaluation testing of an L3-Harris data link system. The proposed operation is planned for 10 flights ending in May 2020. Note: This requested is intended to cover an increase in the output power ERP to 85W (84.15W) for the Air-Directional emission for the currently issued FCC experimental STA license under call sign WP9XLY (File Number: 1933-EX-ST-2019). Please see attachments. STA is required because the data link system transmits in a frequency band (Ku) and at radio frequency power levels that require FCC licensing.

Purpose of Operation

Please explain the purpose of operation:

Data link performance testing. The purpose of this testing is to evaluate the performance of a full-duplex L3-Harris data link system at range and configured as designed between an airborne platform and ground based platform. The airborne system will be installed on Bell Textron’s V-280 tiltrotor aircraft and will consist of two antennas, one directional steerable in a 2-axis configuration pointing back to the ground station and the second being an omni directional antenna. The system is intended to transmit on either the directional or the omni but not both antennas simultaneously. The ground station will be setup at Bell Textron’s Flight Research Center in Arlington, Texas located next to the Arlington Municipal Airport. The ground station will consist of two antennas, one directional steerable in a 2-axis configuration pointing to the airborne system and the second being an omni directional antenna. The system is intended to transmit on either the directional or the omni but not both antennas simultaneously. This testing is only to evaluate the performance of the L3-Harris data link system in this configuration and will NOT be used for remote piloting. The V-280 aircraft will always be human piloted.

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.

Datum:  NAD 83 Is a directional antenna (other than radar) used?   Yes Exhibit submitted:   No (a) Width of beam in degrees at the half-power point:   12.00 (b) Orientation in horizontal plane:   1.00 (c) Orientation in vertical plane:   1.00 Will the antenna extend more than 6 meters above the ground, or if mounted on an existing building, will it extend more than 6 meters above the building, or will the proposed antenna be mounted on an existing structure other than a building?   Yes (a) Overall height above ground to tip of antenna in meters:   2810.00 (b) Elevation of ground at antenna site above mean sea level in meters:   190.00 (c) Distance to nearest aircraft landing area in kilometers:   56.00 (d) List any natural formations of existing man-made structures (hills, trees, water tanks, towers, etc.) which, in the opinion of the applicant, would tend to shield the antenna from aircraft: There is a letter to the FCC that accompanies this submission containing more details. The mobile directional antenna is mounted on an aircraft. The orientation in the vertical plan is negative, but the field will not accept negative numbers so a value of 1 is shown so as not to have a blank field. Although the antenna is capable of rotating 360 degrees, a value of 1 degrees (north) is shown as the antenna will be pointing north as it tracks the base station antenna which is north to stay in alignment for best link margin. The distance of 56 km to the nearest airport is referencing the distance from the center of operations to the Arlington Municipal Airport.
