Abstract:
This paper aims to optimize the spatial coordinates of the locating terminals points of our faculty, initially determined
using GPS technology. Additional measurements were performed to one year interval with another GPS receiver. So
was obtained a new set of coordinates that was used to obtain a better determination thereof by the average of the two
determinations. In order to determine the coordinates of the new points was used GNSS Permanent Stations National
Network using RTK method: RTCM (Radio Technical Commission for Maritime Services). Measurements were
performed with GPS SOUTH S82T and GPS SOUTH S82V, whose field book has implemented software
transcomputation real-time geographic coordinates obtained in STEREO-70 coordinate system. Network of permanent
GNSS stations has used fixed station IASI_2.3 and virtual station RO_MAC_3.1_GG. Solutions for new measured
points were fixed, the determination’s accuracy being ranged from 0.034-0.010 meters. Following these two rounds of
measurements of the spatial coordinates of locating points of the faculty network using GPS technology we obtained a
set of coordinates that increase their accuracy. But also shows that errors occur are due the type of used receiver and
satellite position based on the time of determination, or other types of influences. These errors will be highlighted in
this study to show that sometimes it are important and can`t be neglected during training measurements with these
modern tools.
