Applications

FM data detectors were used in Hughes Galaxy satellite ground stations to demodulate and extract telemetry data from satellite downlink signals. This equipment type supported command and control operations for commercial and government satellite systems during the Galaxy era. Typically integrated into larger ground station racks alongside other RF and baseband processing equipment.

Condition: For Parts or Not Working
This Hughes Aircraft 3814120-100 Galaxy System FM Data Detector is being sold as-is for parts or repair. The unit has not been powered or tested at our facility. Due to its age and the specialized nature of this satcom ground equipment, we cannot make any claims about its functionality. Cosmetically the unit looks to be in decent shape — the front panel and chassis show typical age-related wear consistent with rack use, and the internal boards appear intact with no obvious physical damage visible in our photos. The rear panel connectors (J1, J2, J3) and AC power section appear present and intact. Please view our photo set and contact us if you have any questions.
