Abstract


This paper introduces the usage and reliability of Motorized GPSSIT technique
which is a novel approach for surveying. It reviews the advantages of Motorized
GPSSIT concept and also considers to provide GNSS accuracy in the process of
surveying especially for the cases which cannot be surveyed directly by the satellite
navigation systems (GPS-GNSS), such as closely packed residential areas, tall
buildings, trees, etc., and also places which GNSS receivers cannot be work
efficiently due to signal interferences. In this technique, all the survey instruments
are installed on a bed of a pick-up truck whereas in present techniques they are
installed on the ground, therefore it is called Motorized GPSSIT. Study area was
chosen within the housing area of our campus. In this area, classical surveying,
GPSSIT and Motorized GPSSIT were performed to collect data for comparison and
for the analysis of this technique's usability and reliability. Stop and Go and RTK
surveying techniques were performed with GPSSIT and Motorized GPSSIT
concepts. It is shown that the Motorized GPSSIT technique is applicable as other
present techniques in terms of accuracy and reliability
