CHANNEL FOR MEASUREMENT OF ANGULAR SPEED OF INERTIAL NAVIGATION SYSTEM Russian patent published in 2015 - IPC G01C21/10 

FIELD: instrument making.

SUBSTANCE: channel for measurement of angular speed of an inertial navigation system includes an angular speed sensor (ASS), an analogue-to-digital converter (ADC), a reprogrammable read-only memory (RROM), a control device and a processor. ASS includes a gyroscope with an angle sensor and a torque sensor with a compensating coil, and an amplifier to the output of which the first and the second resistors are connected. The third resistor is connected at a connection point of the same resistors. The control device has a control channel of a follow-up system of ASS, which contains a key, and a reference voltage source (RVS). RVS output is connected to the fourth resistor that is connected to the key input; the key output is connected to the connection point of the first and the second resistors; the key control input is connected to a processor; RROM output is connected to the processor. In RROM there saved is a code of voltage at the connection point of the compensating coil with the first resistor according to design ratio.

EFFECT: providing control of serviceability of an ASS follow-up system.
