INTEGRATED SYSTEM OF STANDBY DEVICES Russian patent published in 2019 - IPC G01C21/00 

FIELD: physics.

SUBSTANCE: invention relates to measurement and indication systems, which provide for piloting of aircraft in case of failure of main flight-navigation systems. Integrated system of standby devices is made in the form of separate unit containing sensors of full and static pressure, connected through signal processing and conversion device with calculator, module of spatial orientation, device for controlling operation modes, a liquid crystal display connected to a computer, a crenobescope, a photosensor connected to the operating mode control device, device for compensating systematic component of zero shift of inertial sensors of spatial orientation module, connected by its input to module of spatial orientation, and its output - to computer. As well as a magnetic probe connected to the ADC output, to the built-in control system, which is connected by its input to the spatial orientation module, to the full and static pressure sensors, and by the output to the calculator. Said reference voltage source connected with ADC output is connected thereto, its output being connected to spatial orientation module.

EFFECT: technical result is high reliability and accuracy of measuring parameters of spatial orientation.
