Resumo
O objetivo deste estudo foi comparar cotas de vértices de uma poligonal, considerando dados coletados por três diferentes receptores GPS, usando como testemunha uma estação total. Os dados foram obtidos em uma poligonal fechada, sendo posteriormente tratados pelo software Topograph. As cotas obtidas pelos três receptores foram confrontadas com aquelas calculadas a partir do levantamento com a estação total, mediante a aplicação do teste t, constatando-se que as mesmas foram satisfatórias para o equipamento GPS Trimble® 4600 LS. Para o equipamento GPS Trimble® modelo PRO XR, as cotas não foram totalmente satisfatórias, mas possíveis de serem consideradas em anteprojetos. Para o equipamento GPS Garmin® de navegação 12 XS, as cotas mostraram-se inaceitáveis para a finalidade estudada.
The objective of this work was to compare cotas of polygonal vertices, through three different receiving GPS, using as reference a total station. The data were obtained in a closed polygonal, being treated later by the software Topograph. The cotas obtained by the three receivers were confronted with those calculated by means of the application of the test, being verified that the cotas were satisfactory for the equipment GPS Geodesic Trimble® 4600 LS. For the equipment GPS Trimble® topographical model PRO XR, the cotas weren't totally satisfactory, but possible of being considered in preliminary projects. For the navigation equipment GPS Garmin® 12 XS the cotas were shown unacceptable for the studied purpose.
