Morphology
The meaning is directly derivable from combining 'gravitational' (pertaining to gravity) and 'field' (a region where a force acts): together they denote the region of space in which gravity operates. Although slightly technical, the compositional structure is clear and mirrors equivalent constructions in many languages, so a B1 learner who knows both words would understand the phrase.
Etymology
Gravitational field comes from the simple picture of an invisible field around a heavy object like Earth: the gravitational part links it to 'gravity' and the field is the space that 'pulls' other things toward the object. So, gravitational field means the area around an object where gravity acts.
