Morphology
The meaning is directly compositional: 'celestial' (relating to stars/planets) plus 'guidance' (controlling a path) yields guidance provided by celestial bodies for navigation. This follows standard noun + noun/adjective–noun composition and is cross-linguistically transparent, so a learner who knows both words would understand the MWE.
Etymology
Celestial guidance paints a clear picture: celestial means stars and planets and guidance means showing the way. Imagine someone using the stars to find the right direction, so the phrase means 'using stars or planets to guide a spacecraft or missile'.
