Reliability and FDIR

Under Construction

PEROVSAT flight software must tolerate radiation-induced faults in low Earth orbit. Fault Detection, Isolation, and Recovery (FDIR) combines hardware protections with software techniques and layered watchdogs.

Topics

• Radiation Events — TID, displacement damage, and single-event effects relevant to LEO
• PEROVSAT Strategy — watchdog layers, safe-mode boot, and software mitigations
• Thread Watchdog — per-thread heartbeat monitoring run by System Health
• Power Management — how EPS-driven OP_STATUS throttles mission behavior

Design notes also live in the public design-and-planning repository under exploration/fdir.md.
