GLONASS/GPS/GALILEO SATELLITE NAVIGATION RECEIVER WITH CORRELATORS, ASYNCHRONOUSLY CONTROLLED BY PERIPHERAL PROCESSOR Russian patent published in 2012 - IPC G01S5/02 

FIELD: physics.

SUBSTANCE: device has a radiofrequency module for receiving GLONASS and GPS/GALILEO signals, a reference oscillation generator, a unit of GLONASS and GPS/GALILEO correlators, a unit for detecting narrow-band interference and an interface converter which is connected through an arbitrary physical interface to an external computer with a universal central processing unit. For efficient suppression of narrow-band interference, a modified replica is loaded into the correlators, which takes into account narrow-band interference generated by the computer based on data from the determining unit. Control of correlators by the external computer takes place in asynchronous mode. To synchronise operation of correlators and an external program, an identifier of the new state of the correlator (StateID) is loaded simultaneously with the replica and other parameters into the correlator from the external computer.

EFFECT: broader functional capabilities.
