The invention provides a spatial two-dimensional high-frequency antenna pointing precision ground calibration method, equipment and a medium. Belongs to the technical field of spacecraft systems. The calibration method is carried out in two parts. In the first part, the relation between electric axis pointing and a prism coordinate system is calibrated in a microwave anechoic chamber environment, and in the microwave anechoic chamber, a planar near-field test system is adopted to calibrate the relation between an antenna electric axis vector and an antenna prism coordinate system; 2, calibrating the relation between an antenna prism coordinate system and a reference prism in a clean room, dividing the four theodolites into two groups, establishing a measuring station, and respectively establishing a driver reference prism coordinate system and an antenna prism coordinate system; according to the method, the influence of earth gravity on antenna deformation can be unloaded, and the antenna pointing error can be calibrated with relatively high precision.
