Determination of Target Map Coordinates using Differential Global Positioning System DGPS & Total Station Device
Alaa S. Mahdi
The determination of a target coordinates in 3-D is an important applications in remote sensing, terrestrial surveying, and civilian / military. In this paper, the DGPS, Real Time Kinematics RTK mode) and Total Station TS system have been used to estimate a target map coordinates (UTM projection, Datum WGS84 ), in real 3-D world. for this purpose, the field of work was prepare that the RTK of DGPS measurements consist of one base point with OPUS correction and 8 rover points. The measurements were done using the Topcon HiPer II system with total root mean square error lees then 10 mm, and Leica TPS1500+ system. Each rover point is use as TS station to shot the TS reflector in three arbitrary points. From the DGPS / RTK mode and TS measurements, the coordinates of the reflector in three positions can be determine in high accuracy lees than 10 cm. Also, the least mean square algorithms was used to evaluate the coordinates of reflector in three points from 8 TS shoots. The field work was done in the Baghdad university camp that avoiding the buildings and tress to reduce the multi path DGPS error. All criteria and results were evaluated by special written subroutine using the Matlab environment. This methods can be used successfully to find the coordinate of any faraway target or movie target.
