| Abstract: | The probability analysis of the rounding error is given for the numerical solution of the differential equations of the quaternions in the strapdown guidance system. First, the probabilistic model of the rounding error in the computation of quaternions on a fixed point computer is established. Then, the probabilistic rounding error estimates are computed. |
