2 Fault Monitoring: Measuring What Matters

Continuous system health monitoring is a cornerstone of effective FDIR implementation. In satellite electronics, the most relevant physical parameters to track are voltage, current, and temperature. These values provide early indicators of abnormal operating conditions, allowing the system to react before permanent damage occurs.

To measure these signals reliably in the harsh environment of space, Texas Instruments offers a wide portfolio of radiation-hardened and radiation-tolerant devices with proven flight heritage and application flexibility.
