Phone Number: 703-404-7563

Explanation
Please explain in the area below why an STA is necessary:
Approval of this STA will allow timely verification of the spacecrafts’ command, control, and telemetry sub-system, as well as audio/video communications payload, if any. Orbital does not anticipate any additional coordination to be required, other than those already existing, for the frequency bands of interest. The parameters of the RF transmissions for this STA are provided in the attachment. It should be noted that additional shielding of emissions is expected since testing will be performed inside Orbital structures, shielded rooms, and/or anechoic chambers. Orbital Sciences manufactures communication and Scientific satellites for commercial and government customers. We must test the Satellite communication systems, both payload and satellite control, to assure that they are fully functional and have been manufactured properly. These are not permanent operations but are temporary and short duration operations. The following characteristics apply: Beginning of Life Radio Frequency Parameters for satellite 1 (Dulles, VA): Frequency Span, Null-Null Bandwidth (GHz) Modulation Type Maximum Effective Radiated Power (ERP) 3.700 - 4.200 Continuous wave (CW) and TDMA (CW) +10 dBW 4.198 - 4.199875 Frequency Shift Keying with Ranging Tones +10 dBW 6.245 - 6425 Continuous wave (CW) +10 dBW Orbital Sciences is aware that other stations may be licensed on these frequencies, and if any interference occurs, transmissions associated with this application will be immediately terminated. Beginning of Life Radio Frequency Parameters for satellite 2 (Dulles, VA): Frequency Span, Null BW (GHz), Modulation, Max Effect. Rad. Power (ERP) 11.69 – 12.18, Continuous wave (CW) +10 dBW 11.69 – 11.71, Phase Shift Keying with Ranging Tones, +10 dBW 17.29 – 17.78, Continuous wave (CW), +1 dBW 17.29 – 17.31, Frequency Shift Keying with Ranging Tones, +1 dBW Orbital Sciences is aware that other stations may be licensed on these frequencies, and if any interference occurs, transmissions associated with this application will be immediately terminated.

Purpose of Operation
Please explain the purpose of operation:  Test of satellite communications systems.

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.

Is a directional antenna (other than radar) used?   Yes
Exhibit submitted:   No
(a) Width of beam in degrees at the half-power point:   0.70
(b) Orientation in horizontal plane:   0.00
(c) Orientation in vertical plane:   0.00
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?   No
(a) Overall height above ground to tip of antenna in meters:  
(b) Elevation of ground at antenna site above mean sea level in meters:  
(c) Distance to nearest aircraft landing area in kilometers:  
(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: We will be operating inside of a metal building. Additionally to the extent possible we will be using anechoic foam panels to absorb the transmitted energy. We only expect a small amount of spill over and will be monitoring the area for personnel safety.
