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:
Aeronautical Radio Inc. (ARINC) hereby requests a Special Temporary Authority (STA) to begin operation on January 15, 2001 in order to complete the INMARSAT satellite aircraft earth station (AES) access approval and commissioning process and to begin ARINCs avionics qualification policy network authorization approval for the SATCOM Aero-I AES. These tests are necessary to maintain a safe and efficient environment for the commercial airline industry. We have recently filed an application with the Experimental Radio Service, FCC file number 0013-EX-PL-2001, but do not expect a decision on the pending application in the near term. We respectfully request your approval of our STA request as soon as possible.

Special Temporary Authority application - Initial values - Purpose of Operation
Please explain the purpose of operation:
Aeronautical Radio Inc is requesting to operate one fixed mobile satellite pallet equipped with Rockwell Collins satellite avionics at our headquarters in Annapolis, MD. The equipment will be operated for the purpose of: a) Test and demonstrate operation of an INMARSAT aircraft earth station (AES) with a Land Earth Station (LES), the ARINC Packet Network (APN) and ARINC Corporate LAN for voice and data applications. The equipment shall operate in the Marine and Aeronautical positions of the Mobile Satellite spectrum. Demonstration of the operational capability of this equipment requires transmitting. No ?FOR HIRE? communications are to be provided during the use of this equipment. DIGITAL VOICE AND DATA The equipment shall transmit one channel of digital voice or data using 8.4 kbps A-QPSK modulation. The system shall use an intermediate gain stationary antenna. In addition, low speed data will be transmitted using an A-BPSK modulation. All modulation complies with ICAO/aviation standards. Ground earth station communication services shall be provided by Comsat Mobile Communication (CMC). OPERATING DETAILS The mobile satellite bands comprising 1626.5 to 1660.5 MHz will be used. Specific frequencies and operating schedules will be coordinated with Inmarsat, in cooperation with CMC. RF Power Output The maximum RF power output of the equipment will be 25 Watts per carrier (14 dBW peak). Antenna Gain An intermediate gain antenna shall be used to provide a gain 6 dBic (nominal) and half power beam width of 60 degrees. EIRP The maximum equivalent isotropic radiated power (EIRP) shall be 23 dBW (peak). Emission Types Emission Type Modulation Type Symbol Rate Convolutionally Encoded Rate 840HG1D A-BPSK 600 baud 600 bps ½ FEC 1K68G1D A-BPSK 1200 baud 1200 bps ½ FEC 6K72G1W A-QPSK 4.2 kbaud 8400 bps 2/3 FEC Modulation Methods Type Description A-QPSK Aviation Quadrature Phase Shift Keying uses a specific form of Offset QPSK where the modulation filtering is optimized for satellite communications with aviation applications (Reference: ?Quaternary Transmission Over Satellite Channels with Cascaded Non-Linear Elements and Adjacent Interference? by Russel Fang in IEEE Transactions on Communications, May 1981, Vol. COM-29, No. 5, pp 567-581.) A-BPSK Aviation Binary Phase Shift Keying uses a specific form of differentially encoded BPSK where in-phase and quadrature channels are used to transmit alternate symbols. (Referenced: ?Differential Detection With Intersymbol Interference and Frequency Uncertainty? by J.H. Wintore in IEEE Transactions on Communications, January 1984, Vol. Comm-32, No. 1, pp. 25-33.) Necessary Bandwidth Radiated bandwidth from the equipment is controlled by the use of raised cosine filters in the transmitter. The A-QPSK are signals subjected to either a 60% or 100% raised cosine filter. The associated necessary bandwidth calculation is: BW=1/T(1+r) Where 1/T is the symbol transmission rate in symbols per second and r is the roll-off factor. Symbol Rate (Baud) Modulation Type Rolloff ( r ) Bandwidth (BW) 600 A-BPSK 0.4 0.840 kHz 1200 A-BPSK 0.4 1.680 kHz 4200 A-QPSK .6 6.720 kHz
