INTEGRATED BACKUP DEVICE SYSTEM Russian patent published in 2017 - IPC G01C21/00 

FIELD: physics.

SUBSTANCE: invention relates to measuring and indicating systems. The integrated backup device system is designed as a separate unit and contains total and static pressure sensors connected through a signal processing and converting device with a calculator, a spatial orientation module, a mode control device, a liquid crystal indicator connected to the calculator, a photosensor connected to the mode control device, a device for compensating for the systematic zero displacement component of the inertial sensors of the spatial orientation module connected with its input to the spatial orientation module, and with its output - to the calculator, a built-in control system connected to the spatial orientation module, to the total and static pressure sensors, and with the output - to the calculator. A current regulator is additionally introduced, the output of which is connected to the first input of the switch and the brake sensor. The other output of the brake sensor is connected to the measuring resistor, to the second and the third input of the switch, the output of which is connected to the analog-to-digital converter, the input of which is supplied with voltage from the reference voltage source, and the output is connected to the calculator.

EFFECT: increasing the functionality of the unit and the accuracy of calculating the true speed of the flying object.
