Morphology
The meaning is directly compositional: 'navigational' relates to navigation (determining position/course) and 'system' denotes a collection of interacting components, so together they clearly refer to a system used for navigation. This follows standard noun + modifier composition common across languages, so a B1 learner who knows both constituents will readily infer the MWE meaning.
Etymology
The term navigational system comes from the idea of putting tools for navigation, like a compass, map and stars, together into one system that helps find a ship's place and direction. So today it means 'a set of instruments or devices that tell position and course'.
