Horizontal reference is center of 5/8 UNC brass screw, vertical reference is top of leveling brass bolt. VLBI Center of vertical axis of VLBI antenna. PRARE Steel tower fixed to a reinforced concrete block. The station is marked by a brass marker in the concrete block. 10317M001 Steel tower fixed to a reinforced concrete block. As reference, a brass marker is fixed in the concrete block. 10317M003 Steel tower fixed to a reinforced concrete construction blasted into solid bedrock. The point is defined as the top center of the hole in the horizontal top plate, through which a special machined 5/8 UNC screw can be put to fix an antenna or other geodetic instrument. CHAMP
