Navigation Fault Detection

Navigation Fault Detection is a space control that finds off-nominal behavior before it becomes a mission-impacting failure for position, timing, and trajectory services. It uses telemetry thresholds, trend checks, and operator review so teams can choose a safe response while keeping evidence, reliability, and public-safe operational boundaries clear.

“The mission team used Navigation Fault Detection when the navigation solution was updated, so the team could choose a safe response before the next mission decision point.”
