A New Technique of Position-Fixing for Site Vehicles

Abstract

A New Technique of Position-Fixing for Site Vehicles B. Gorham Pages 717-726 (1996 Proceedings of the 13th ISARC, Tokyo, Japan, ISSN 2413-5844) Abstract: This paper reviews the development of an automatic laser theodolite LASERFIX first designed at the University of East London in 1979 and since that time protected by a number of international patents. Applications of that theodolite to surveying, robot calibration and tunnelling machine guidance are introduced, and the specific problems of 3- dimensional guidance of site vehicle are examined. Practical problems and performance capability for both off-vehicle and on-vehicle location of the laser theodolite is discussed. In both cases the design requirements for laser beam sensors or beacons is analysed and practical solutions proposed. Finally, a new receiver version of LASERFIX is introduced which does not require the use of lasers but which offers similar capabilities and performance. The paper concludes with a report of experimental tests of the new device aimed at assessing it's capability in the position-fixing of site vehicles.
