This quantity relies on a global symposium held in Rio de Janeiro. It provides a development record on geodetic positioning with GPS. the upkeep and the densification of reference frames are handled for the aim of building worldwide and local GPS networks. The medical achievements of the South American Geocentric Reference approach undertaking (SIRGAS) are defined. numerous contributions overview the cutting-edge of GPS research innovations, ambiguity solution equipment, in addition to GPS antenna and location difficulties. Novel functions of kinematic GPS positioning and qc problems with real-time GPS positioning are mentioned.

It should be noted that in this paper, accuracy is defined as the difference between the assumed true value of the position of a station (ITRF93 values) and the estimated one. This is expressed by the root mean square (RMS) coordinate differences. For the purpose of this paper, precision is defined by the session to session coordinate repeatability, namely the RMS of the coordinate differences from each session solution from the weighted mean coordinates of all the session solutions. The daily Earth Rotation Parameters obtained in the tests have also been compared with the corresponding estimates made by four IGS Analysis Centres, over the same 5 day period.
