gravimeter

The work of Stanley and Vezzoli [12] has been able to mathematically describe from first principles the detailed gravimeter data of Wang et al.

Relative gravity testing was done every 10m along profiles of about 500m in longitude, using a Worden gravimeter. The cycles were done in periods of less than 2 hours and by the same surveyor, seeking to minimize the level of human error.

We provided evaluating measurement with relative gravimeter LaCoste&Romberg model G on 8 stations of the network.

Gravity readings are stored into the internal memory of the gravimeter.

For the Geodetic observatory Pecny at Ondrejov, CZ ([phi] = 49[degrees] 55' and [lambda] = 14[degrees] 47'), we have the absolute gravity data measured by the absolute gravimeter FG5, No.

The compatibility of the original signal and its reconstruction was proved at the level of [10.sup.-4]nm/[s.sup.2] which is three times better than the sensitivity of the gravimeter. As a result of the decomposition process of the time series, diagrams were obtained for each time series at which each of the components represents a different frequency--the higher the number of the component, the lower the frequency is (Fig.
