UNIT OF STRAPDOWN ORIENTATION SYSTEM INCLUDED INTO SYSTEM OF VISUALISATION AND REGISTRATION OF MOBILE OBJECT MOTION Russian patent published in 2008 - IPC G01C21/10 G01P15/08 

FIELD: physics, measurement.

SUBSTANCE: invention is related to measuring equipment. Unit of strapdown orientation system contains microcontroller, interface board and three measuring units, every of which contains micromechanical gyroscope and accelerometer. Outlets of every gyroscope and accelerometer are connected with corresponding inlets of analog-digital transducers, inlets of every gyroscope are connected with corresponding outlets of digital-analog transducers. Every gyroscope and accelerometer are located in measuring unit on separate printed circuit boards. Measuring axis of gyroscope is perpendicular to plane of printed circuit board and parallel to axis of Cartesian reference system, and measuring axes of accelerometer are parallel to plane of printed circuit board and to corresponding axes of Cartesian reference system. System of visualisation and registration of mobile object motion contains switching device, unit of data collection and transmission, which collects measured data from at least one unit of strapdown orientation system, and exchanges data with computing device of strapdown navigation system, which receives information about motion parameters of at least one object from computing device of positioning system, which consists of positioning system transmitters and basic receivers of positioning system, which provide acceptance of signals from transmitters of positioning system, computing device of motion visualisation and registration system, which receives information about value of linear and angular coordinates of objects from computing device of strapdown navigation system.

EFFECT: higher accuracy of operation and measurement of object motion.
