ANÁLISE COMPARATIVA DE RECEPTORES DE POSICIONAMENTO POR SATÉLITE PARA LEVANTAMENTO PLANIMÉTRICO DE IMÓVEIS RURAIS

Abstract

With the increasing need to carry out surveys with high accuracy to comply with the norms for geo-referencing rural properties, however, surveys are carried out with the use of inadequate equipment, leading to errors in positioning and dimensioning of areas and perimeters. This work intends to clarify this fact, performing a comparative analysis between the coordinates obtained for navigation receivers and geodesics. The following equipment was used in the research, Trimble R4, Trimble R4 RTK Trimble R3, Garmin 60CSx. A total of 24 points of vertices were collected from an area on the experimental farm of the National Institute of the Semi-Arid - INSA, where the Planimetric maps were generated from the information obtained using a Geographic Information System (GIS) software. The results obtained show that there is distortion in the surveys performed, since the data collected by a Garmin 60 CSx GPS receiver presented differences of 1.34% in the area obtained in relation to the geodetic receivers, which were reliable for the works in the Precision agriculture proving its high accuracy.
