Internal and External Reliability in the Paraná Scientific Gravity Network

Abstract

This work presents the conceptions, strategies and experimental activities associ- ated with a new methodology of establishing high precision gravity network in Brazil. The survey was accomplished with four spring gravimeters, three LaCoste & Romberg and a digital Scintrex gravimeter. The principal objective of this work is to present and to apply the criteria for geodesic network reliability. The work makes an analysis of which solutions for the network is better, taking into account the precision and reliability.
