Abstract in Portuguese
A crescente demanda por informações gravimétricas consistentes em âmbito sul-americano, visando, sobretudo, a unificação de um sistema altimétrico para o continente, foi a motivação maior deste trabalho. Nesse contexto, procurou-se evidenciar informações detalhadas, de cunho técnico e operacional, voltadas à execução de levantamentos gravimétricos. Assim, conceitos básicos introdutórios seguidos de uma resenha histórica da gravimetria no Brasil e no mundo, são delineados. É efetuada a proposta de uma nova abordagem para um sistema gravimétrico. Apresentam-se aspectos práticos detalhados sobre o manuseio do gravímetro LaCoste & Romberg. Sugerem-se, adicionalmente, procedimentos metodológicos para as diversas etapas de uma operação gravimétrica. Ao final, à guisa de estudo de caso, disponibilizam-se resultados que são analisados e comparados.

Abstract in English
The increasing demand for consistent South American gravimetric informations, aiming, most of all, the unification of a height system for the continent, was the motivation for this work. Within this context, an effort was made to evince detailed technical and operational informations related to the execution of gravimetric surveys. Basic concepts are exposed, followed by a historical summary of gravimetry in Brazil and throughout the world. A proposal of a new approach for a gravimetric system is made and detailed practical aspects on the use of LaCoste & Romberg gravity meter are given. In addition, methodological procedures are suggested for the several stages of a gravimetric operation. Finally, as a case study, results are made available after analysis and comparisons.
