6 Ensuring Power Availability With Smart Redundancy

In space systems, power supply robustness is not just important—it is mission critical. If a power rail fails, recovery options are extremely limited. Therefore, many satellite designs implement redundant power supplies to maintain continuous operation of vital subsystems.

At first glance, redundant supply design may seem straightforward. However, when implemented properly, it involves careful coordination of detection, isolation, and timing mechanisms.
