ATTACHMENT 2 ANTENNA SPECIFICATIONS

AURA-LE Antenna Specification Sheet The AURA-LE AES antenna is a mechanically steered phased array antenna using CoMPA™ (Coherent Multi Plate Antenna) technology. It is comprised of two dual-polarization panels with full receive and transmit bandwidth capability. The system is designed as two receive/transmit flat panels with appropriate provisions for coherent combining of the two flat panels to form effectively one larger elliptical narrow beam receive/transmit array with an elevation range of 0º to 90º.

Now MELCO seeks new PCU : Polarization Control Unit applications for the antenna. The Mitsubishi Electric Corporation (MELCO) Ku—band Aeronautical Mobile Satellite antenna is designed for AMSS applications. An El over Az antenna mount is employed to lower the antenna profile. The antenna receives linearly polarized signals from a GEO satellite in the 11.2 — 12.8 GHz band, covering the Ku band frequency allocations in all ITU regions. The diplexer and LNA are installed behind the main reflector. Dual polarization signals can be received. Transmission to the satellite is linearly polarized in the 14.0 — 14.5GHz band. A 40 watt Solid State Power Amplifier (SSPA) having more than 21.9 % efficiency is employed for high data rate transmission with less heat dissipation. The up and down frequency converters are installed separately from the antenna main unit. The IF frequency is in the 950 — 1,450 MHz band. Az/El angles of the antenna are controlled by an Antenna Control Unit (ACU) to track the satellite. The ACU determines the fuselage‘s attitude from an aircraft Inertia Reference Unit (IRU) and Az/El estimates are provided by angular rate sensors in the ACU. Any drift of IRU and/or rate sensors can be compensated by periodical step tracking iterations. To meet FSS requirement the polarization angle setting is precisely controlled. Given the angles toward a targeted satellite and the stored data of the transponder polarizations in the onboard equipment, the polarization angle is calculated in the ACU. The antenna transmit polarization angle is determined by the power ratio between two orthogonal linearly polarized components. The power ratio is controlled by the phase shifter of Variable Polarization Controllers (VPCs) of the Polarization Control Unit (PCU.) As a result of precise The antenna on the fuselage polarization control, low Cross Polarization Discrimination (XPD) can be achieved.
