GRAVITATIONAL CONSTANT MEASUREMENT METHOD Russian patent published in 2015 - IPC G01V7/00 

FIELD: measurement equipment.

SUBSTANCE: in the above said method, a measurement process is started after setting-up of balls with known weight is completed and a holder is removed, when the balls begin performing free movement in a field of gravitation of these balls. Upon completion of setting-up, movement speeds of one ball relative to another ball and balls relative to a measurement satellite are minimum. From the measurement satellite, balls are irradiated with laser light. Some part of laser light is supplied to inputs of optic receivers in the form of a reference signal; recording of dependence on time of an interference pattern of a reference signal with laser light reflected from the first ball and from the second ball is performed. Then, dependence on time of the interference pattern of the reference signal with the laser light reflected subsequently from the first ball towards the second ball and from the second ball to the measurement satellite is recorded, and dependence on time of the interference pattern of the reference signal with laser light, which is reflected from the above balls, is recorded. Dependence on time of distances from the measurement satellite to each ball is recorded by means of a pulse distance meter. Having determined the change in time of distance between balls, gravitational constant is calculated.

EFFECT: improving accuracy of determination of a gravitational constant.
