The valuation of accuracy of the absolute gravimeters of GP-05 type
© Svetlov S.M., Kopyl V.K.
The present state and trends of absolute gravimetry are discussed. The main attention is paid to a problem of the absolute gravimeter systematic errors. The accuracy of a Ukrainian absolute gravimeter, of the GP-05 type is evaluated using experimental data. As a result, a discrepancy of the order 0,080 ìGal between the GP-05 and the FG5 absolute gravimeters is found; a systematic bias of the order of 0,040 ìGal of the first order gravity station «Kharkov» is detected; interpretation of the obtained results is given. Taking the systematic error into account, the final accuracy of the absolute and relative gravity measurements with the GP-05 gravimeter is estimated as 0,010-0,015 and 0,020 ìGal respectively. <<back |
