Abstract

This invention relates to a surveying instrument for determining the accurate position of an unknown terrestrial point relative to a fixed terrestrial point. The instrument has a head which is securable to a tripod or other fixed support and is orientatable at a desired angle relative to the surface of the earth. The head has a number of sighting rods projecting from it and each rod has a fixed end which is attachable to the head and a free end opposite the fixed end. Each free end provides a a known fixed point which enables a geometric parameter between said fixed point and an unknown point to be determined and, consequently, the accurate position of the unknown point relative to the fixed point and head to be calculable by trilateration.
