Applications

This command generator was used in satellite ground control facilities for Galaxy II and Galaxy III satellite systems. The unit processes and transmits RF command signals to control satellite operations. It integrates with ground station telemetry and monitoring systems via multiple interface standards common to 1980s-2000s telecommunications infrastructure.

Condition: For Parts or Not Working
This Hughes 3814100-100 RF Synchronous Command Generator is being sold as-is for parts or repair. It has not been tested and no functionality is guaranteed. The chassis shows typical age-related wear consistent with satellite ground station service — the rear panel has some surface yellowing/oxidation on the beige paint. The front touch display panel and control buttons are physically intact. Interior boards (A2 ASSY 3814102 REV F and A3 ASSY 3808473 REV D) are present and appear undamaged visually, though no power-on test was performed. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
