Comparative Study on Static versus Real-Time GNSS Measurements and Altitude Differences between GNSS Determinations and High-Precision Leveling

Abstract

In Romania, it is possible to determine the position of points with the help of real-time GNSS receivers, using the ROMPOS application of the National Agency for Cadastre and Real Estate Advertising through the National Cartography Center. The application is used where there is a signal on the mobile phone and ensures an acceptable accuracy not only in planimetric but also in altimetric positions. Lately, controversies have arisen regarding the accuracy of the results obtained with the help of the ROMPOS application, versus the static method, both horizontally and at altitude. This paper aims to demonstrate that the results obtained with the ROMPOS application fall within the precisions requirements for current works.
