X Band Satellite Communications Terminal

Stay connected to the major X-band satellite constellations no matter where you fly.

Overview

The X-band Satellite Communications on-the-move broadband antenna system is a low-profile, dual-axis mechanically steered, satellite tracking antenna. Designed to give customers ultimate flexibility, the system was developed to support airborne or ground-based communications on-the-move applications over the major X-band constellations including Wideband Global Satellite Communications, Skynet and XTAR, as well as other current and future spacecraft hosting X-band payloads. While utilizing two interleaved, wideband apertures for simultaneous, full duplex Tx/Rx, the X-band antenna system enables the ability to switch right/left hand circular polarizations for both Rx and Tx. The antenna’s low profile reduces the size of traditional dish reflector radomes used for similarly capable X-band communications by nearly half and can be shaped as conformal to an allocated swept volume as necessary.

Key Benefits:

Small, lightweight, low profile minimizes drag and fuel consumption improving time on station; only 55 pounds with a swept volume diameter of 31" and height of 11.5"
Slot array design can be made conformal to nearly any allocated area while tightly controlling the resulting beam patterns
Separate, interleaved Tx/Rx apertures utilize alternating slots and achieve high Tx/Rx isolation
Performance equivalent to a 40 cm dish but with a lower profile 10" x 20" aperture
Dual-axis mechanical positioner with no scan loss for constant gain regardless of azimuth or elevation angle
Optional polarization switching enables ease-of-handoff between separate constellations with opposite polarizations
Dynamic stabilization suitable for either airborne or ground mobile applications
Supports either ARINC 429 or autonomous navigation modes
