INTEGRATED STRAPDOWN SYSTEM OF NAVIGATION OF AVERAGE ACCURACY FOR UNMANNED AERIAL VEHICLE

摘要

FIELD: instrument engineering.;SUBSTANCE: invention can be used in small-sized strapdown inertial navigation systems (SINS) integrated with a variety of external systems of unmanned aerial vehicles (UAVs). SINS comprises: a unit of sensing elements (SE), a unit of calculation of linear and angular velocities and geographical coordinates, a unit of generating the signals of damping, the units of quaternion calculations, the unit of calculation of the matrix of directing cosines and angles of orientation, the receiver of signals of satellite navigation system (SNS), the unit of determining the quality of SNS signal, the switch of vector signals, the first and second adders-subtractors of vector signals, the unit of air data system (ADS), the unit of determining the heading error, the unit of determining and correction of the wind speed.;EFFECT: improvement of accuracy.;2 dwg
