Testing of the accuracy of Leica TCRP 1201 total stations, Topcon GPT-7001 and Topcon GPT-8203M

Abstract

The Institute of Geodesy and Mine Surveying VŠB-TU Ostrava bought new total stations – TCRP 1201 made by Leica, GPT- 7001 by Topcon and GPT-8303M by Topcon. TCRP 1201 is a motorized total station extended by GPS – SmartStation. GPT 7001 is a total station with a pulse rangefinder. The GPT-8203M motorized total station also has a pulse rangefinder and it is possible to use it as a 3D scanner. Among others, each of these total stations enables non-prism measuring. It is common to test whether a new geodetic apparatus meets characteristics declared by the manufacturer before it is introduced into everyday usage. The testing of geodetics apparatus procedures on IGMD are proceeded in such a way they correspond with the CSN ISO 17123 standards. Besides these standard procedures the tests were extended by non-prismatic measuring properties testing.
