Applications

Satellite command generators were deployed in ground control stations to transmit coded commands to orbiting spacecraft. This unit supported Hughes satellite systems and SSEL ground support networks, handling tone and digital command generation, signal routing, and system status monitoring. Typically integrated into larger telemetry and command subsystems for mission-critical satellite operations.

Condition: Used
This SSEL Hughes 7746600-100 Satellite Command Generator VME rack has been inspected and powers on — the front panel status LEDs illuminate as seen in our photos. We were not able to fully test this unit's satellite command functions at our facility, so it is being offered in as-inspected, powers-on condition. All five VME plug-in cards are present and seated: Force Computers SYS68K CPU-4VC (P/N 100413), Motorola VMEmodule MVME 335 (P/N 01-W3530B), Tone Analog (P/N 7729257/7729257-099), RZ Tone Digital (P/N 7742917), and Utility (P/N 7742911). The chassis shows typical wear consistent with prior professional use. Please view our photo set and contact us if you have any questions.
