Abstract
A new AVHRR image navigation software package has been developed. Both direct and indirect image navigation capabilities are provided. An ap proach is used in which the orbital motion model for the satellite is an independent module. The attitude of the spacecraft is also modeled and the capability to estimate the attitude from ground control points is included. Descriptions of the various orbital and attitude models are presented along with the navigation algorithms. Image navigation e xamples, including attitude recovery from ground control points, are a lso shown. Overall, it is found that the software can provide navigati on accuracies to within 1 km.
