Lacoste and romberg gravity meter
WebThe LaCoste and Romberg gravity meter designed for operation in gimbals was redesigned for satisfactory stabilized platform operation and a suitable stabilized platform was made. A major modification of the gravity meter was redesign of the suspension to more nearly restrict motion to a single degree of freedom. WebThe reliability and ruggedness of LaCoste‐and‐Romberg gravity meters has meant that their use has extended over recent years from gravity mapping to the investigation of small gravity changes (> 10 μGal) with time. When using the instrument at the limit of its capability, limitations become apparent.
