DGDT - Downsized Ground Data Terminal
EL/K-1871
General The DGDT is a lightweight, transportable communications terminal. lt is designed to provide a data link interface between ground or shipboard command and control stations and airborne reconnaissance platforms.
Features Range: 50 to 200 Km (LOS) Full duplex communications: - Command (CM) uplink, - Video & Telemetry (TM/TV) downlink, or - TM - Only downlink.
Backup Navigation: range & azimuth AC/DC world wide power supply Fully remote controllable via RS-422 line BIT: on-line and off-line
Description The DGDT implements a modular architecture; the baseline DGDT configuration may be augmented, via user selected options, for additional performance.
Antenna Posi Positioner: A light weight Elevation-overAzimuth pedestal; enables manual or automatic positioning and antenna track modes.
Baselline DGDT consists of the following LRUs: Base
