METHOD AND DEVICE FOR EVALUATING NAVIGATION PARAMETERS OF CONTROLLED MOBILE OBJECTS Russian patent published in 2004 - IPC

FIELD: instrumentation engineering; inertial control systems for evaluating navigation parameters of controlled mobile objects.

SUBSTANCE: sensing element of platform-free control system is mounted on stage in gimbal suspension, stage is rotated relative to object at speed close to that of object but different in sign, measurements are made of parameters of translational and rotational motion of stage, angular position and of object body relative to stage, measurement data obtained are processed, and navigation parameters of object motion in inertial space are calculated. Inertial system device implementing this method has gimbal suspension accommodating stage that mounts three accelerometers and three angular velocity sensors; angle sensor and motor are mounted on gimbal suspension axle; stage is revolved by means of motor at speed approaching that of object under control but in opposite direction; sensing element signals are processed and parameters of object movement as well as its positioning are found by means of computer that sums up signals proportional to turn angles of stage relative to base system of coordinates and signal arriving from angle sensor mounted on stage suspension axle.

EFFECT: enhanced measurement accuracy.
