matrix firstly. This matrix is employed to transform the body angular increments from the RLGs and the body velocity increments from the accelerometers in the sensor reference frame..., in this work, an improved navigation computation scheme is proposed. Firstly, the sensed angular increments are approximately integrated and used to compute a direction cosine matrix . This direction cosine......
