Cubic's GATR Technologies has developed GATR TRAC, a new version of its inflatable antenna with tracking capabilities, that can be deployed in locations where this capability is traditionally limited.

Tracking antennas are used to communicate with satellites in non-geostationary orbits, as well as with other moving objects such as aircraft. However, legacy systems require a rigid dish with heavy-duty structural support making them difficult to use in many situations.

GATR's inflatable tracking antenna can follow moving targets, and features improved reliability, a simple user interface and upgraded assembly and disassembly procedures. The GATR TRAC can be packed into four cases which provide greater overall flexibility for mission planning. It can be assembled in around 30 minutes.

The GATR TRAC is a 2.4 metre, lightweight antenna that features mechanical and electrical components in a ruggedised base with support arms that allow the antenna to track satellites moving across the sky.

GATR TRAC has been demonstrated to reliably track satellites in low Earth orbit and produce usable imagery as part of a deployable ground station. It also has the ability to track satellites in other types of orbits.
