ABSTRACT:
A method of automatically determining attitude of a moving vehicle. Acceltion of the moving vehicle is measured with gyro stabilized accelerometers. The measurement is converted to a motion related vector in a first frame of reference. The coordinates are read into a computer. The cosine value and the sine value for an Euler rotation of the first frame of reference are read into the computer. The computer produces coordinates of the vector in a rotated frame of reference. The above two steps are repeated a number of times to arrive at a final frame of reference. The attitude of the vehicle is provided with respect to a final frame of reference with the aid of final produced coordinates.
