INERTIAL-SATELLITE NAVIGATION, ORIENTATION AND STABILISATION SYSTEM Russian patent published in 2009 - IPC G01C21/00 

FIELD: physics; navigation.

SUBSTANCE: invention relates to navigation satellite corrected inertial navigation and gyrostabilisation systems for sea objects and can be used on ships and other vessels in a wide range of navigating conditions. The inertial-satellite navigation, orientation and stabilisation system has a gyrostabilised platform in a triaxial cardan suspension with angle sensors, on which are mounted three rate integrating gyroscopes and three accelerometres, digital device, corrector, where outputs of the angle sensors for rotation of the rings of the cardan suspension and outputs of the accelerometres of the gyrostabilised platform are connected to inputs of the digital device, one of the outputs of which is connected to the input of the gyrostabilised platform, and the other to the corrector. The inertial-satellite navigation system is fitted with a control console which generates system control signals, and the system is also fitted with an accelerated correction unit, the input of which receives current values of coordinates of navigation satellites used, generated by the satellite receiving device and current device values of parametres of orientation of the gyrostabilised platform, a channel switch for standard and accelerated correction, where outputs of the correctors are connected to inputs of the switch, outputs of which are connected to the digital device.

EFFECT: determination of course error from coordinate data of only two satellites of a satellite navigation system and current device parametres of orientation of an object, generated by an inertial navigation system.
