31 How Does the GLOBETrekker Work? The GLOBETrekker system diagram can be reviewed in Figure 11 GLOBETrekker Block Diagram. The GLOBETrekker consists of the Baseband Assembly, Motorized Azimuth/Elevation Assembly, Antenna/RF Assembly, and a AC-DC power supply. Subcomponents of these assemblies are identified below. Details of each of these subcomponents have been included in this chapter under relevant subsections. Baseband Assembly The Baseband Assembly combines the following: • Baseband unit with: • iDirect iConnex iNFINITI Modem • Single Board Computer 1(900MHz) with Microsoft ® XP Embedded Operating System and Norsat LinkControl application software • 5-port Ethernet Switch • DVB-S Receiver • Spectrum Analyzer • DC-DC Converter • GPS Receiver • Custom Frame with Foldable Legs • Protective Jacket Motorized Azimuth/Elevation Assembly The Azimuth/Elevation (Az/El) assembly houses the following components: • Elevation Azimuth (Az) Unit • Azimuth Main and Rotational Plate with Feedback Components • Motor Control Board (inside) • Azimuth Motor (including gear box) • Azimuth Motor Manual Override 1 Single Board Computer = SBC. A single-board computer is a complete computer built on a single circuit board. The design is always centered around a microprocessor.
32 Antenna/RF Unit The RF/Antenna unit includes the following components: • 1m segmented (6) carbon fiber antenna reflector • Quick-connect BUC/SSPA assembly • Inclinometer • Lower boom arm segment (with transmit fixed waveguide and Harmonic filter) • Upper boom arm and feed assembly (includes Transmit fixed waveguide and Receive Reject filter, and motorized cross-pol compensated feed/OMT/Transmit Reject filter assembly) • LNB quick-connect assembly set (3) • Transmit flexible waveguide • Compass/GPS antenna unit Transmit Path The transmit side of the uplink chain starts at the Baseband unit with the modem output IF frequency in the L-band range of 950 – 1700 MHz. The exact output frequency is selected by the modem and is a function of the final carrier frequency at the antenna output. The frequency conversion is achieved by the block upconverter (BUC), which shifts the L-band output frequency of the modulator to a desired higher (Ku-band) frequency. The BUC is paired with a Solid State Power Amplifier (SSPA). All BUC/SSPA options (4W, 8W, 12W, 15W and 20W) are hermetically sealed and are mounted to the back of the reflector. More powerful BUC/SSPA options (25W or 40W) can also be supplied as needed (not integrated). The output of the BUC/SSPA is fed to the Harmonic (HRF) and Receive Reject Filter (RRF) filters. Harmonic reject filters attenuate all harmonics produced in the BUC/SSPA due to its nonlinearities. Similarly, RRF filters provide attenuation outside the desired transmitter band; specifically receive frequency range from 10.95 GHz to 12.75 GHz, preventing Receive performance degradation due to the injection of noise from the transmit to receive path. Finally, through a flexible waveguide the transmitter signal is applied to the antenna feed through an Orthogonal Mode Transducer (OMT) which isolates the outbound signal from the receive signal. The feed horn feeds energy into the antenna. The directivity of the feed horn is added to that of the antenna resulting in a pattern that is a narrow and concentrated beam.

34 Antenna Parameters The GLOBETrekker is available in both the regular transmit frequency range of 14.0 to 14.5 GHz and in the extended frequency band of 13.75 GHz to 14.5 GHz. The transmit gain on the antenna is 41.9 dBi at 14.125 GHz. On the receive side, the frequency coverage is from 10.95 GHz to 12.75 GHz, segmented into three sections: 10.95 GHz to 11.70 GHz 11.70 GHz to 12.20 GHz 12.25 GHz to 12.75 GHz The measured gain at the receive Ku-band is 39.5 dBi at 10.95 GHz (worst case scenario). The G/T of the antenna is: 19.4 dB/K at 10.95 GHz for an elevation angle of 10 degrees an antenna temperature of 430 K and the LNB noise figure of 0.8 dB The antenna is linearly polarized where the polarization selection can either be Vertical/Horizontal (V/H) or Horizontal/Vertical (H/V) on the transmit and receive sides. Complete details of the antenna parameters are shown in Table 3 Antenna Parameters.

36 Receive Path The isolation between the transmit and receive side is achieved through the use of the OMT (Ortho Mode Transducer) and the TRF (Transmit Reject Filter). The TRF serves to further isolate the two sides with the receive polarization being orthogonal to the transmit polarization. The Ku-band receive signal at the output of the transmit reject filer, at the input of the LNB, is at the standard Ku-band frequency (10.95 GHz to 12.75 GHz). A block Down-Converter translates the RF frequency into an L-band output (950 MHz to 1700 MHz) required by the modem. The output of the LNB is also fed to the spectrum analyzer to assist with pointing the antenna and to facilitate system monitoring. Modem down-converts, demodulates and decodes the incoming signal. The data is then routed to its destination via the integrated 10/100 Mbps auto-negotiating Ethernet switch. The G/T of the terminal is 19.4 dB/0K at a 100 elevation angle. Modem (iDirect) The iDirect iConnex iNFINITI modem is capable of operating in Hub-Spoke, Star, and Mesh modes. It can also use the same Hub to support Star, Star/Mesh, and SCPC topologies. The modem supports multi frequency operation (MF-TDMA) on a burst-by-burst basis. The modem enables outbound signaling from the hub to the spoke terminals in TDM with data rates of up to 17.8 Mbps. Inbound signaling from the spokes to the hub in DMF-TDMA is currently possible at data rates of up to 4.2 Mbps. Turbo Product Code (TPC) forward error correction is: Inbound (spoke to Hub) 0.660 or 0.793 Outbound (Hub to spoke) 0.793 Table 4 Baseband Parameters shows the details for Baseband unit.

38 Power Configuration Options for the Assemblies The GLOBETrekker is designed to operate both with DC as prime and AC as an optional power source. The AC/DC power supply has universal, auto-sensing, AC input allowing operation with 110/220 VAC. The input frequency into the AC/DC power has a range of 47 to 63 Hz. A stable input DC power is generated for terminal electronics when the AC variation is limited on the lower voltage side to 92 volts or over -15% variations at the input. A DC-to-DC converter translates the 24V DC to +5V and +12V. This is required for different parts of the electronics. Baseband Connections: Baseband – Antenna/RF Interface There are five connections originating at the baseband unit. These connections provide the user control over the operation of both receive and transmit functions as well as control of the SSPA and access to the alignment tools via the LinkControl software interface. Receive IF (Rx) Cable The Receive IF (Rx) cable is a 50 ohm coaxial cable with a N-type male connector. This connector has been color coded green. The signals supplied on this interface are: Receive IF: the received signal amplified and downconverted by the LNB and supplied to the baseband unit 24V DC: supplied to the LNB This interface does not supply a 10 MHz signal.
39 Transmit IF (Tx) Cable The Transmit IF (Tx) cable is a 50 ohm coaxial cable with a N-type male connector. This connector has been color coded red. The signals supplied on this interface are: Transmit IF (950 to 1700 MHz) signal to be upconverted, amplified and transmitted to the satellite. This signal may either be a continuous wave (CW) or modulated signal. 10 MHz reference: provides a reference signal for the BUC (Block Upconverter) 24 V DC: supplied to the BUC (Block Upconverter) The transmitter (or BUC), that is located at the base of the antenna, needs the 10MHz signal in order to be unmated and operational. SSPA Monitoring and Control (M&C) and DC Cable The SSPA M&C and DC cables consist of a 24 AWG and 16 AWG wire cable with a multi-pin amphenol female connector. The signals supplied on this interface are: SSPA Current: provides indication of the SSPA current consumption. This measurement is displayed in LinkControl Status screen and is used in the power control algorithms. SSPA Mute Control: allows the SSPA to be turned OFF/ON via LinkControl.
