Dual AN/GSC-52 antennas

USA / Maryland / Fort Meade /
 military, antenna

The AN/ GSC-52( V) is a fixed or mobile, medium-size SHF SGT designed for use with the DSCS space segment. It is a high-capacity, high-altitude electromagnetic pulse (HEMP) protected terminal that uses pseudo-monopulse scanning for operator-selectable manual tracking, memory tracking, or acquisition/auto tracking of the satellite. The terminal consists of an antenna subsystem, a receive subsystem, a transmitter subsystem, and tracking/ servo subsystem.
The antenna subsystem has a Cassegrain feed, 38-foot parabolic-reflector antenna, an elevation over azimuth pedestal, and a servodrive mechanism. Modems provide a 70 or 700-MHz IF to the up-converters whose RF outputs are combined into a single RF signal in the 7.9 to 8.4 GHz range with a bandwidth as wide as 500 MHz. The composite signal is amplified by the TWTA and fed, via waveguides, to the antenna subsystem. On the receive side, the antenna receives an RF signal at 7.25 to 7.75 GHz, amplifies the signal using LNAs and the interfacility amplifiers, and passes the signal to down-converters which provide a 70 or 700-MHz IF output to the modem.
