Morphology
The meaning is directly and transparently derived from 'navigational' (related to navigation) combined with 'instrument' (a tool or device). This adjective+noun composition follows a common, cross-linguistic pattern, so a B1 learner who knows both constituents can infer it denotes a device used for navigation.
Etymology
The phrase navigational instrument comes from the simple idea of a tool that helps someone navigate, for example a compass pointing north or a sailor using the stars. That's why it now means 'a device to find position, direction, or course'.
