Scientific paper

A method of determining the earth's gravitational field by low-orbit satellite-to-satellite observations is described. Two satellites move on the same low circular orbit about 200 km from each other. The relative difference in the velocities of the satellites is measured with the aid of radio Doppler equipment. This difference is a function of gravitational anomalies below the orbit. A variant of this type of experiment is proposed, in which two subsatellites are released from a mother satellite. An observational equation is derived from energy conservation principles, and an equation for determining the distance from the geoid to the ellipsoid is given. For an accuracy of 1 m, the necessary accuracy in relative velocity measurement is 0.05 mm/sec.
