Morphology
inertial + navigation + system
The phrase is directly compositional: 'inertial' (relating to inertia/motion), 'navigation' (determining or controlling a route), and 'system' (a set of components) combine to mean a system that navigates by using inertia/internal motion measurements. Although the item is technical and may require domain knowledge about sensors, the core meaning is predictable from the constituents for a learner who knows those words.
Etymology
Inertial navigation system comes from the idea of finding position by measuring an object's own motion. 'inertial' points to 'inertia', the tendency of something to keep moving, 'navigation' means finding direction, and 'system' is the set of parts that do the work, so the name shows it can track position using internal motion sensors without outside signals.
