AEROGRAVIMETRIC COMPLEX Russian patent published in 1997 - IPC

FIELD: study of gravitational field, in particular, cartography of Earth gravitational anomalies. SUBSTANCE: device uses on-board and ground equipments. The on-board equipment has an autopilot, astroinertial navigation system, receiving display of the satellite navigation system, three gravimeters, radio, laser altimeters and an altimetric barometer, barometric vertical velocity meter connected to a computer with an information storage. The astroinertial system is formed by installation of an astrotracker on the gyroplatform of the inertial navigation system, the astrotracker output connected to the computer. The same gyroplatform carries the on-board gravimeters. The astroinertial system is installed in a container, which is furnished with a shock absorber of low-frequency inertia accelerations. The ground equipment uses a ground or bottom gravimeter, receiving display of the satellite navigation system installed at a geodetic station, and a receiving display of the satellite navigation system installed at a controlled station, all connected to a computer. EFFECT: enhanced accuracy. 4 cl, 5 dwg
