Figure 2 : HGA-6000 & Slimline HGA-6000 High Gain Antennas
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:
o The HGA-6000 is capable of interfacing directly to the ARINC 429 interface of an SDU (as
defined in ARINC 741 [1]). 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. This configuration is depicted in Figure 1.
o 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.
