NONORTHOGONAL GRAVIMETERING COMPLEX Russian patent published in 2002 - IPC

FIELD: instruments for graviinertial measurements. SUBSTANCE: nonorthogonal gravimetering complex has an internal navigation system, satellite navigation system, altimeter, computer with a Kalman filter and a binary filter, information storage, radiomodem unit, helicopter hovering stabilization unit. Three and more gravimeters are nonorthogonally installed on the gyrostabilized platform of the inertial system. The gravimeters are positioned at distance L one from another and positioned in generator of a cone with a semi-angle at vertex α. Four outputs of the computer are connected to the outputs and the respective inputs of the inertial system, helicopter hovering stabilization system and radiomodem unit. The computer comprises a unit for estimation of the reliability of gravimeterings. EFFECT: enhanced accuracy and reliability of graviinertial measurements on a movable pedestal. 2 cl, 2 dwg
