DEVICE AND METHOD TO MEASURE GRAVITATION Russian patent published in 2000 - IPC

FIELD: geology, geophysical prospecting, high-precision navigation. SUBSTANCE: measurements are taken with the aid of acceleration transmitter mounted on moving carrier, satellite navigation receiver and computer. In the interests of vector gravimetry there can be used several acceleration transmitters, satellite navigation receiver for complete measurement of inertial acceleration should determine orientation in addition to position. Computer to integrate measured complete acceleration with inertial acceleration to determine gravitation can be used separately (under off-line condition). Besides, digital filtration of measured accelerations is improved considerably as compared with "physically blind" filtration of low frequencies thanks to proper selection of coefficients of filter matched in optimum way to stochastic characteristics of gravitational field of the Earth. EFFECT: usage of simpler and less expensive accelerometer, realization of vector gravimetry, that is, determination of complete gravitation vector and provision for definition of thinner structures of gravitational field of the Earth by means of air and sea gravimetry. 11 cl, 4 dwg
