CPN: 832-5150-001 Rev:-Rockwell Collins, Inc.Page 4 of 232 Exhibit 1 - Product Description SRT-2000 The SAT-2000 Satellite Communications System, an all solid-state aircraft earth station (AES) that operates as part of the SATCOM system, is designed to be compatible with the INMARSAT AERO-I services. The SAT-2000 system consists of the SRT-2000 Satellite Data Unit and IGA-2000 Intermediate Gain Antenna. The SRT-2000 is a multi-channel receiver-transmitter that provides both voice and data channel to its users. The IGA-2000 Intermediate Gain Antenna allows the SAT-2000 to transmit and receive data and voice traffic efficiently; the diplexer/low noise amplifier is integrated into the antenna to improve system performance and reduce the number of line replaceable units (LRU). Aero-I is intended for medium and short-haul airliners, but is also suitable for aircraft in the long-haul market, which fly mainly within the spot beam coverage. The use of a smaller system allows the SAT-2000 to take advantage of the spot beam feature of the Aero-I satellites to provide the benefits of telephony, fax, and real-time data communications. The SAT-2000 system has a 25 W high power amplifier (HPA) that supports up to six channels (1 data - 5 voice) within the spot beams. 1.1 SRT-2000 Satellite Receiver-Transmitter The SRT-2000 transmits and receives packet mode data to/from the data link system (ACARS or CMU), and receives and transmits circuit mode services (voice) in analog form to/from the flight crew headphones and microphones via the audio management unit(AMU). Additionally, the SRT-2000 receives and transmits circuit mode data (voice, FAX, or PC MODEM) from passengers via an ARINC 746 compatible cabin telephone unit (CTU). Support of secure voice using STU-III compatible telephones is also available with the installation of an optional Cabin Interface Unit (CIU-906). The system also includes interfaces to optional on-board maintenance systems (CMC, CFDS, etc.) for system fault annunciation. The SRT-2000 incorporates the ARINC 741 defined functions of the high power amplifier, RF unit (RFU), beam steering unit (BSU), and satellite data unit (SDU) into a single 8 MCU unit that weighs less than 35 lbs. CPN: 832-5150-001 Rev:-Rockwell Collins, Inc.Page 5 of 232 The SDU function of the SRT-2000 is the interface to all other aircraft systems. It contains all data processing functions, modems and channel tuning synthesizers including a voice CODEC (coder-decoder) and synthesizer pair for each voice channel. The RFU function converts the broadband intermediate frequency (IF) from the SDU portion to L-band frequency before the signal is applied to the HPA function of the SRT-2000. The RFU function also accepts an amplified L-band signal from the low noise amplifier (LNA)/Diplexer and down converts it to the IF used by the SDU function. The HPA function amplifies the signal for transmission. The HPA function feeds a measurement of the actual power transmitted back to the SDU function. The SDU function uses this measurement for power management. The SRT-2000 also contains a 10.24-MHz high stability reference (HSR). The HSR generates high precision injection frequencies and digital clocks from this reference. CPN: 832-5150-001 Rev:- Rockwell Collins, Inc. Page 6 of 232 1.2 Equipment Specifications CHARACTERISTIC SPECIFICATION Physical Size 8 MCU Weight Less than 35 LB (6-channels) Electrical Input Power 97 to 134 VAC, 400 @ 40 Hz, single phase or + 28 VDC Receiver input Frequency range 1530 - 1559 MHz VSWR 2:1 max over input frequency range, 50 Ohms nominal Transmitter output Frequency range 1626.5 to 1660.5 MHz Output level 25 watts (maximum) CPN: 832-5150-001 Rev:-Rockwell Collins, Inc.Page 7 of 232 1.3 Hardware Overview The block diagram below shows the function partitioning of the SRT-2000. 1.4 Mechanical The SRT-2000 is housed in an 8-MCU-size unit with mounting requirements according to the ARINC 600 specification. The front panel contains a standard ARINC 615 dataloader connector and a set of LEDs to indicate unit and system status. It also contains a “self-test” button and corresponding LED indicators for active operator maintenance. Electrical connections are made through an ARINC 761 compliant, ARINC 600 rear connector. CPN: 832-5150-001 Rev:-Rockwell Collins, Inc.Page 8 of 232 The unit consists of a power supply module, RFU module, HPA module, HSR, system processor, ARINC 429/Discrete input/output module, and channel modules. The functions are partitioned into logical functions on circuit cards. The removable, plug-in circuit cards mate with a sideboard interconnect card. The circuit cards are all connected together via a system address bus and system data bus. The design of the unit architecture specifically allows many of the processing functions to be accomplished digitally by the microprocessors and associated memory circuits. 1.5 System Processor Module The system processor maintains the same architectural design as the SDU-906 Satellite Data Unit. It provides high-level system processing and controls communications with all slave processors; it can reset or reprogram any of the slave processors. In addition to processing the signal strength and amplitude information to support the RFU module, the system processor performs the following functions: (1) power control and attenuator control functions; (2) data control and routing; (3) user interfacing for selection of system parameters; and, (4) antenna steering and pointing computations. The system processor accesses all memory-mapped devices in the other modules as if those devices were located in the system processor module. It interfaces to the other modules in the unit through a 24-MHz multiplexed address/data bus. Through this bus, the system processor communicates with the CEPT function, the ARINC 429 function, and the DSPs of each channel module. One interface is common to all the modules. The system processor does not allow the other proce…

The electrical characteristics of the radio frequency load attached to the output terminals when this test is made shall be stated. Section 2.1033 (c) (8) The dc voltages applied to and dc currents into the several elements of the final radio frequency amplifying device for normal operation over the power range. Section 87.131 Notes (1), (ii), (8) (1) The power is measured at the transmitter output terminals and the type of power is determined according to the emission designator as follows: (ii) Peak envelope power (pX) for all emission designators other than those referred to in paragraph (I) of this note. (8) Power may not exceed 60 watts per carrier. The maximum EIRP may not exceed 2000 watts per carrier. 9.4.2 Test Results The SAT-2000 System output power to the antenna is equal to the power output from the High Power Amplifier (HPA) in SRT-2000, less the losses between the HPA and the antenna. These losses include cable loss, LAN/Diplexer loss, and CPN: 832-5150-001 Rev:- Rockwell Collins, Inc. Page 138 of 232 other interconnection losses. They are installation dependent and are specified below: Cable Loss = 3.70 dB maximum LNA/Diplexer Loss = 0.8 dB maximum Total HPA to Antenna Loss = 4.50 dB maximum Typical values for these losses measured are: Cable Loss = 1.1 to 3.7 dB LNA/Diplexer Loss = 0.5 to 0.8 dB Total HPA to Antenna Loss = 1.6 to 4.5 dB The HPA rated output power is 25 watts maximum for multiple carriers. The DC supply voltages and typical DC current values for the HPA are listed in the table below.
