THREE-COMPONENT ANGULAR SPEED METER Russian patent published in 2006 - IPC G01P9/02 

FIELD: measurement technology.

SUBSTANCE: three-component angular speed meter can be used in platform-free inertial radar systems. Speed meter has three angular velocity detectors with mutually perpendicular axes, three three-input adders, and six inverting amplifiers. First inputs of three-input adders are connected with outputs of relating angular velocity detectors. Inputs of first and second inverting amplifiers are connected with output of first angular velocity detector. Inputs of third and fourth inverting amplifiers are connected with output f second angular velocity detector. Inputs of fifth and sixth inverting amplifiers are connected with output of third angular velocity detector. Second and third inputs of first three-input adder are connected with output of third and fifth inverting amplifiers. Second and third inputs of second three-input adder are connected with output of first and sixth inverting amplifiers. Second and third inputs of third three-input adder are connected with output of second and fourth inverting amplifiers. Angular velocity detectors can be made in form of fiber-optic angular velocity detectors or in form of rotor vibration gyroscopes either in form of laser gyroscopes or in form of micro-mechanical gyroscopes. Amplification factor of any inverting amplifier depends on degree of influence of angular velocity, measured by that angular velocity detector, which has output connected with input of converting amplifier, on angular velocity detector, which has output connected with first input of three-input adder and which has the other input connected with output of inverting amplifier.

EFFECT: improved precision of measurement.
