GRAVITATION METERING SET Russian patent published in 2000 - IPC

Abstract RU 2150132 C1

FIELD: instrumentation engineering. SUBSTANCE: two inertial navigation systems are connected through their outputs to inputs of computer whose other inputs are connected to satellite navigation system and altimeter. Computer uses Kalman filter and binary filter. Speed and vertical position error estimates picked off filter output are passed to inertial navigation system for error correction. EFFECT: improved measurement accuracy. 8 cl, 1 dwg, 1 tbl
