What does the term "positioning integrity" signify in E-NAV systems?

Positioning integrity in Electronic Navigation (E-NAV) systems specifically pertains to the accuracy of positioning information provided by navigational aids. This concept is essential in ensuring that a vessel or vehicle can precisely determine its location, which is critical for safe navigation and operations. Integrity essentially refers to the confidence users can have in the accuracy and reliability of the positional data received.

In navigation systems, if positioning information is not accurate, it can lead to catastrophic consequences, such as running aground or colliding with obstacles. Therefore, understanding and ensuring the positioning integrity is vital for any navigational system to function effectively and safely. Accurate positioning is fundamental to maintaining proper situational awareness and making informed navigational decisions.
