COMPARISON OF GPS STOP AND GO METHOD AND ELECTRONIC TACHEOMETRY TECHNIQUE IN MAP PRODUCTION
The NAVSTAR GPS is a satellite-based radio navigation system providing precise three dimensional position, navigation and time information to suitably equipped users. The system consists of 24 satellite placed in orbits of about 20.200 km altitude above the earth surface. GPS has three segments. These segments are space, control and user. In this study, classical tacheometric method and the GPS Stop and Go measurements are compared. For this purpose, İstanbul Technical University’s Maslak Campus was chosen as the application site. At the comparing the methods, the 437 common points on the pavement sides especially are labelled by means of paint and then these points are measured by using both methods. Finally, their coordinates is calculated at the National Coordinate System (ED 50). The coordinate differences of 437 common points, simultaneously used both methods, are calculated and the obtained coordinates and coordinate differances are compiled in the form of tables.
