SIGNAL PROCESSING DEVICE Russian patent published in 2018 - IPC G01C21/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of aircraft instrumentation and can be applied in integrated systems using information with a noisy signal, in particular from the satellite navigation system (SNS), and ensuring the integrity of the navigation information of the system. In a signal processing device comprising a path numbering system, a corrector, a Kalman filter, a first and second adder, wherein one of the radix output path coupled to a first input of the initial control information, a first output connected to the first inputs of the first and second adders, the second input of the first adder connected to the output of the corrector, and the output is connected through a Kalman filter to the second input of the second adder is further introduced dial, and four adders and five blocks of computing devices, some of which form a correction unit, wherein the primary information control unit is further connected by a first output to the first inputs of the third and sixth combiners interconnected through the correction unit including the first connected unit of the computing devices, an input connected to the output of the third adder, a fourth adder, a second unit of computing devices, a fifth adder, and a third block of computing devices, that in turn is connected to a second input of the sixth adder, wherein the correction unit also includes a serially connected fourth block of computing devices connected to the output of the input of the fifth adder, fifth computing block devices coupled output to the second input of the fifth adder, and the sixth computing block devices coupled to output to the second input of the fourth adder.

EFFECT: expansion of functional capabilities on the basis of a decrease in the gradient of changes in navigation parameters and an increase in the level of accuracy of the estimated parameters of the location and speeds of the aircraft.
