The GDT-2100 Ku-band ground data terminal (GDT) antenna system from TECOM Industries is a portable, light-weight, military-grade tracking antenna system for ground-based Ku-band data link transmit and receive communications. Currently in active service by US forces in overseas operations, the commercial-off-the-shelf (COTS) system includes a 4-ft. antenna, Ku-band feed, two-axis positioner, integrated control system, tripod mounting base, and transit cases. The positioner features continuous azimuth travel and highly effective tracking using pointing commands derived from GPS position information. RF beam autotrack configurations are available for applications where GPS position information is not available. The system is used to exchange imagery and data from unmanned aerial vehicles (UAVs) employing common data link (CDL) or other Ku-band data links.
