UNIFIED AIRCRAFT NAVIGATION SYSTEM Russian patent published in 2016 - IPC G01C23/00 

FIELD: instrument making.

SUBSTANCE: invention relates to instrument making and can be used in navigation systems and navigation equipment of aircraft (AC). For this purpose, unified navigation system comprises interconnected via digital communication channels (DCC) set of navigation-piloting systems (NPS) and an on-board digital computer system (BDCS), wherein the set of DCC includes navigation-piloting aircraft system (NAC) of various physical principles action, such as inertial navigation system and vertical courses, air signals system, satellite navigation systems, radio-technical system near and far-field navigation, Doppler ground velocity meters, radio altimeters, system of visual correction , correlation-extremum navigation system and radio system, and BDCS includes computation-logical functional modules (FM) input/output data preparation system, primary information processing, complex information processing, determining parameters of Earth, determining navigation parameters, calculation of parameters of great circle, converting coordinates, determination of control parameters, control system, control modes of operation of the system, information support of decision making and formation of output parameters, additionally introduced the BDCS FM scanning and identification of connected to DCC NPS, FM database protocols for communication of NPS and FM unification of input information from NPS.

EFFECT: technical result is expansion of functional capabilities.
