ASTRONOMICAL SIGHTING SYSTEM Russian patent published in 2016 - IPC G01C21/02 

FIELD: astronomy.

SUBSTANCE: invention relates to astro-inertial navigation systems. Distinctive feature of disclosed astro-viewing system is that output signal processing unit of tele-unit additionally includes a second switch, first input connected to second output of cyclic counter, second input connected to second output of storage, while its output is connected to fourth input of adder-accumulator, and in unit for detecting a star and determining coordinates thereof second output of first comparator unit is connected to second input of fifth comparator unit, first input of fourth comparator unit is connected with output of star coordinate storage unit when output signal of adder-accumulator of output signal processing unit of tele-unit passes through zero, and second and third inputs respectively with second outputs of second and third comparators, and third output of fourth comparator unit is connected to first input of newly introduced sixth comparator unit, second input is connected to output of fifth comparator unit and output is connected to input of returned unit for determining coordinates of viewed star, output of which is connected to input of unit for generating detection feature of viewed star.

EFFECT: high accuracy of viewing star.
