In space navigation, the Right Ascension of the Ascending Node (RAAN) is a crucial parameter that defines the orientation of a satellite's orbit. It essentially tells you where the orbit crosses the Earth's equator from south to north. Here's a breakdown of RAAN and its significance: What...
The choice of this parameter defines the initial phase angle between the GPS and Galileo constellation and is a potential driver for the performance of the overall system. Since natural orbit perturbation mechanisms cause an altitude dependent drift of this parameter, this phase angle is also ...
Due to perturbation factors, the Right Ascension of Ascending Node (RAAN) of space objects changes consistently, causing regular rotation of the orbit plane around Earth's axis. Based on the investigation of the RAAN perturbation rate of concerned objects, this paper proposes a RAAN discretization ...
