Morphology

reference + grid

The meaning is directly and transparently derivable from the constituents: 'grid' denotes the pattern of intersecting lines and 'reference' indicates its function as a point/standard for locating positions, so a learner who knows both words can infer a grid used for reference/coordinates. This is a straightforward noun-noun composition following common English and cross-linguistic patterns, making it immediately comprehensible to a B1 learner.

Etymology

The noun reference grid comes from the picture of a grid, many straight lines that cross like graph paper, and the word reference because each crossing gives a clear point to name. That's why it means the pattern of lines on a map you use to find a place by its 'coordinates'.
