ABOUT INERTIAL-SATELLITE NAVIGATION SYSTEM WITHOUT RATE GYROS

The problems of determination of the rigid body kinematical parameters of motion are considered, namely: the problem of determination of the angular rate and velocity of the rigid body's point by the results of the velocities measurements in the body's three points, and the problem of determination of the angular acceleration and acceleration of the rigid body's point by known angular rate and results of the accelerations measurements in the body's three points. On the basis of developed algorithms the possibility of creation of inertial navigation system using readouts of 6 accelerometers and avoiding usage of the rate gyros is considered. Results of this system simulation allow making conclusion about possibility of such system usage as a part of the integrated navigation system. Thereupon the algorithm of the integrated navigation system operation is considered. In order to estimate the accuracy of this system operation the numerical example is presented.
