Checking Satellite Health & Status at the Joint National Test Facility

Three System 500 Model 550s are being used at the Joint National Test Facility at Falcon Air Force Base to support satellite commanding activities for both the Ballistic Missile Defense Organization’s (BMDO) and the Space and Missile Systems Center Test & Evaluation Directorate’s (SMC/TE) growing number of satellite missions.

For program operations, test engineers use the 550 to control and monitor satellite health & status, and/or collect, process, and distribute satellite payload data.  The 550 can accept multiple telemetry downlinks from multiple satellites, process that data using a single real-time front-end processor, and visually monitor real-time events on multiple UNIX-based workstations.  By automating system functions through flexible alarm processing and intelligent software using Expert System technology, the user-friendly Model 550 quickly and clearly identifies system anomalies as they arise.

The Model 550 saves the BMDO and the SMC/TE time and money because it packs the functionality of what once required numerous systems into a single chassis.  The system is so advanced, yet so easy to use that less sophisticated operators can man the controls, freeing test engineers for other mission-critical tasks.  And because the technology is available right off the shelf, engineers at the Joint National Test Facility are free to integrate the system with any third-party equipment they choose.
