Apparatus and method is provided for propagating the attitude of a vehicle. A slew rate is computed based on angular rotation increments associated with a time interval. An incremental update is computed for the associated time interval based on an angular rate and the slew rate. An attitude of the vehicle is propagated based on the computed attitude increment and an initial attitude at the start of propagation.
Keywords: attitude, slew rate
