Aferição do marco geodésico homologado pelo IBGE localizado na UFCG, Campus Campina Grande.

Abstract

The human kind need to understand its living space stimulated the emergence of Geodesy. This science has been providing important contributions over the years to various scientific fields, including the Civil Engineering, adding new essential data and applications towards society’s life quality increase. Prominent among these applications are the geodesic landmarks. Managed by the Instituto Brasileiro de Geografia e Estatística – IBGE, these landmarks are the basis to many studies and projects, once they provide us precise geographic location and altimetric values. Thus, the focus of this paper was to verify the precision of planimetric and altimetric data of the landmark RN1832G located on the Universidade Federal de Campina Grande, Campina Grande campus. In this regard, the data were collected with the help of two different GNSS equipment: a dualfrequency geodesic GNSS and a navigation GNSS. After processing the obtained data, a comparative analysis between the results and the data of the IBGE geodesic station, related to the RN1832G landmark, was conducted. The achieved results point out that the geodesic GPS obtained a more significant convergence to the actual position of the landmark.
