Why is redundancy important in electronic navigation systems?

Redundancy is crucial in electronic navigation systems primarily because it significantly enhances reliability and safety. When multiple systems or components are in place, they can serve as backups for one another. In the event that one part fails, the redundant system can take over, ensuring that navigation continues without interruption. This is particularly important in maritime and aviation environments, where system failures could lead to dangerous situations.

Redundancy can also mitigate risks associated with human error or environmental factors that may affect a single navigation system. Having alternative systems can provide different data points and improve overall situational awareness for operators, making informed decisions based on a more comprehensive view of the navigation environment.
