Morphology
The noun phrase is directly compositional: 'terrestrial' means relating to the Earth/ground and 'guidance' means control of a path, so together it denotes guidance that comes from or pertains to the Earth (e.g., ground-based guidance). A B1 learner who knows both words can reasonably infer this basic meaning even if the technical detail about gravitational-field response is specialized.
Etymology
Terrestrial guidance comes from a simple image: using the Earth's own pull to steer a flying missile. The word terrestrial means 'from the earth' and guidance means 'help to move in the right way', so the phrase describes a method that uses the earth's gravity to control a missile's flight.
