METHOD OF DETERMINING SPATIAL ORIENTATION ANGLES OF AIRCRAFT AND DEVICE THEREFOR Russian patent published in 2016 - IPC G01C19/44 

FIELD: data processing; instrumentation.

SUBSTANCE: invention relates to inertial navigation systems and can be used for determining angular orientation of mobile objects of any type. Invention comprises combined processing of measurements of overload sensors and measurement of speed of mobile object using a satellite navigation system (SNS) without angular velocity sensors. Angular velocity is determined by parametric identification, minimising functional quality, which is formed from acceleration differences obtained by differentiation of flight-path velocities measured using SNS and accelerations, obtained by processing overload signals on three axes of aircraft. Device implementing present method comprises a unit of overload sensors, satellite navigation system, a unit for determining linear accelerations, unit for generating matrix of guide cosines, composite function determination unit, differentiation unit, unit for minimisation of composite function, angular velocity determination unit, unit for determining initial orientation angles and integrator, connected to each other in a certain manner.

EFFECT: simple method, reduced cost and high accuracy of determining angular orientation of object in absence of onboard devices for measuring angular velocities.
