Abstract

GRADIâMETRO GRAVITACIONAL, INSTRUMENTO GRADIOMÉTRICO DE TENSOR COMPLETO E METODO. Um acelerômetro e pacote de sensores de taxa para auxiliar os gradiômetros gravitacionais SãO providos, O acelerômetro e o pacote de sensores de taxas são montados diretamente sobre ou dentro de um gradiômetro gravitacional (GGI). Saídas a partir dos sensores podem ser usadas para reduzir ruído indesejado devido a taxas de rotação angular, acelerações angulares e acelerações lineares que podem estar ligadas ao GGI. Uma vez que o conjunto de sensores é montado diretamente sobre ou dentro do GGI, o conjunto de sensores é acoplado ao GGI e detecta a aceleração e as taxas angulares conforme vistas pelo GGI. Desse modo, as saídas a partir do GGI podem ser corrigidas mais efetivamente utilizando as saídas do conjunto de sensores.
