FIELD: instrumentation.
SUBSTANCE: device to detect angular position of a movable object comprises two three-component magnetometers, a three-component block of sensors of angular speeds, a three-component accelerometer, a calculating device and a Kalman filtering device, placed on a movable object and connected to each other in a certain manner. Detection of angles of spatial orientation is carried out by means of a unit of Kalman filtering by recurrent method. Correction of the magnetic course is carried out by signals of the three-component accelerometer.
EFFECT: increased accuracy and provision of autonomous detection of angles of spatial orientation of an aircraft under conditions of manoeuvring in flight, small time of readiness, hidden works and absence of errors accumulation in time.
