862-A0059 Cobham Aviator HGA-6000 High Gain Antenna, Aeronautical
The HGA-6000 is the smallest mechanically steered SwiftBroadband, Swift64 and Aero H/H+ SATCOM Antenna.
Specifically designed for mounting under the tail radome of an aircraft, the HGA-6000 is the first antenna of this type to accept steering commands directly from any ARINC 741 compatible Satellite Data Unit.
This eliminates the need to install a separate Antenna Control Unit (ACU) or Beam Steering Unit (BSU), reducing system box count, and improving empennage weight distribution and installation simplicity.
Overview
The HGA-6000 antenna is intended for use in an airborne satellite communication system, providing access to the Inmarsat Aero H, H+, Swift64 or SwiftBroadband systems.
The antenna complies with the requirements for an Inmarsat Aero High Gain Antenna as defined in [4].
The only difference between the HGA-6000 and the Slimline HGA-6000 is a reshaped dust-cover designed to cater for different mounting/space requirements.
The HGA-6000 interfaces to suitable avionics that will provide the required modulation/demodulation, RF amplification and the correct beam steering commands.
Two interfaces are provided for controlling the antenna:
An ARINC 429 Interface and a Coaxial Modem Interface: The HGA-6000 is capable of interfacing directly to the ARINC 429 interface of an SDU In this configuration the antenna will accept the commands normally intended for a Beam Steering Unit (BSU). This will also allow the antenna to control the DLNA.
Alternatively, the co-axial modem interface allows the HGA-6000 to be used in conjunction with an Cobham Beam Steering Unit or Satellite Data Unit. The drawings in the manual do not show this method, although block diagrams of the installation option utilizing this interface are given in Appendix A.
