Ramsden theodolite - The Ramsden theodolite is a large theodolite (American English: transit) which was specially constructed for use in the first Ordnance Survey of Southern Britain. The theodolite was commissioned from Jesse Ramsden, a leading Yorkshire instrument maker, who had developed the technique of dividing angular scales accurately to within ...

Theodolite - A theodolite (Amer. "transit") is an instrument for measuring both horizontal and vertical angles, as used in triangulation networks.

Tachymeter - A tachymeter (also tachymetre or tacheometer) is a kind of theodolite used for rapid measurements and determines, electronically or electro-optically, the distance to target, and is highly automated in its operations. Tachymeters are often used in surveying.

Tribrach (instrument) - In surveying science, a tribrach means an instrument attachment plate containing three thumbscrews (see theodolite). The device consists of two triangular metal plates, which are connected at their corners by thumbscrews.
