Control network consists of reinforced concrete pillars drilled into solid
bedrock. 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.

Old IGS
Steel tower fixed to a reinforced concrete block. As reference, a brass
marker is fixed in the concrete block.

New IGS
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.
