| Description | This report presents the mathematical technique for calculating the amount of time that an astronomical object, e.g., a star, can be observed from a satellite in near Earth orbit. This includes the places and times in the orbit where the object is acquired and where it is lost. Constraints placed on the observation of the object, such as the line-of-sight from observer to the target must not come within less than some specified angle to the limb of the Earth, are included in the calculations. The equations developed within the report are then used for a detailed analysis of the observation possibilities for objects at any place on the celestial sphere for a typical Spacelab ASTRO mission. The results, presented in graphic form, are suitable for use in pre-mission planning and also for use in real-time replanning. |
