This paper reports on the results of attempts to reduce the positioning error of strap down inertial navigation system using attitude information obtained by star tracker. In this regard, the position error equations of different channel in inertial navigation are modeled and error share of each sensor in position and attitude determination drifts are investigated. In continue celestial navigation and the use of star tracker in attitude determination and positioning on different frames are considered. Then, new equations of inertial navigation aided by attitude determined with star tracker are introduced. Through the use of the new equations, attitude and position in navigation and inertial frame are recalculated and compared with the parameters obtained by inertial navigation. The results suggest a considerable reduction in position error, particularly in the height channel.
