Exhibit 1 - Product Description SRT-2100 The SAT-2100 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-H/H+ and I services. The SAT-2100 system consists of the SRT-2100 Satellite Data Unit and a High Gain Antenna Sub-System. The SRT-2100 is a multi-channel receiver-transmitter that provides both voice and data channel to its users. The High Gain Antenna Sub-System allows the SAT-2100 to transmit and receive data and voice traffic efficiently. Aero-H/H+ and I are intended for medium and long-haul airliners. The use of a smaller system allows the SAT-2100 to provide Aero-H/H+ and I services to aircraft in the short-haul market enabling business and regional aircraft to receive the benefits of telephony, fax, and real-time data communications. The SATCOM system has a 45 Watt High Power Amplifier (HPA) that supports up to three channels (1 data - 2 voice). 1.1 SRT-2100 Satellite Receiver-Transmitter The SRT-2100 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-2100 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-2100 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 30 lbs (typical 28.9 lbs). Rockwell Collins Proprietary InformationPage 12 of 232 Figure 1.1 SRT-2100 Satellite Receiver/Transmitter The SDU function of the SRT-2100 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-2100. 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-2100 also contains a 10.24-MHz high stability reference (HSR). The HSR generates high precision injection frequencies and digital clocks from this reference. Rockwell Collins Proprietary InformationPage 13 of 232 1.2 Equipment Specifications CHARACTERISTIC SPECIFICATION Physical Size 8 MCU Weight Less than 30 lbs (3-channels) Electrical Input Power 97 to 134 VAC, 324 to 800 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 45 watts (maximum) Rockwell Collins Proprietary InformationPage 14 of 232 1.3 Hardware Overview The block diagram below shows the function partitioning of the SRT-2100. Figure 1.3 SRT-2100 Functional Block Diagram 1.4 Mechanical The SRT-2100 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. Rockwell Collins Proprietary InformationPage 15 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 processors to run until after the SRT-2100 is reset and releases the other processors from reset after it has been determined that the other processors have valid software loaded.

The output of the scrambler is then applied to a convolutional encoder. The generator polynomials are: G1: 1 + X 2 + X 3 + X 5 + X 6 G2: 1 + X + X 2 + X 3 + X 6 The generated polynomial outputs are combined in a punctuated 1/2 rate before the encoded data stream is applied to an interleaver of block size of 384 bits in 6 columns. The output bit stream of the interleaver is organized into words of 3 blocks of 384 bits each. The 3 blocks of data are preceded by a 4 bit format identifier and a 12 bit superframe counter and is appended with a 32 bit unique Rockwell Collins Proprietary InformationPage 23 of 232 word for a total word length of 1200 bits. Four (4) words are subsequently organized into a superframe before it is applied to the modulator. The binary phase shift keying (BPSK) modulator phase shifts a subcarrier by -90 or +90 degrees depending on the input word data bit being a 0 or 1, respectively. The subcarrier signal now contains the information and is upconverted for transmission. 1200 BPS A-BPSK with differential encoding Square Root 40% Raised Cosine Filter Input wavetrain formulation: The input binary data stream is first applied to a scrambler with a 15-stage shift register which has a feedback polynomial of 1 + X + X 15 .
