ABSTRACT:
A surveying instrument comprises a tripod with a tribrach that receives both a theodolite and a C-bracket that half vertically encircles the theodolite. The C-bracket and the theodolite are each independently pivotable on the same vertical axis and the C-bracket is able to completely orbit around the theodolite such that it can be positioned so as not to optically interfere with the use of the theodolite. The top of the C-bracket provides a mount for a navigation satellite receiver antenna that positions the axis of rotation of the C-bracket through the electrical center of the antenna.
