COMPENSATION PENDULOUS ACCELEROMETER Russian patent published in 1998 - IPC

FIELD: inertial navigation systems of mobile objects. SUBSTANCE: proposed device includes two pendulous accelerometers. Sensitivity axes of these accelerometers are directed in same way and their output axes are directed in opposition along one line. Output of device is connected to controlling inputs of commutator and coupling box. Box connects output axes of pendulous accelerometers into one. Output of feedback amplifier of each pendulous accelerometer is connected through commutator to input of transmitter of moment of proper pendulous accelerometer and to input of adder of analog signals. Output of adder is connected through commutator to input of transmitter of moment of each pendulous accelerometer. Outputs of commutator are outputs of device. EFFECT: provision for precise calibration of zero drift and scale coefficient. 1 dwg
