<para> X-ray pulsar-based navigation (XNAV) using one X-ray detector is investigated as an augmentation to the capability of an ultraviolet (UV) sensor-based satellite autonomous navigation system. The satellite state dynamics are analyzed to establish the dynamical equations of the satellite autonomous navigation system. A time transformation equation that accounts for relativistic effects...
In recent years, X-ray navigation (XNAV) has become of great interest for spacecraft autonomous navigation. The XNAV system can be used as an augmentation to the current navigation capability or as a backup to the Global Position System (GPS) and the deep space network (DSN). In this paper, the XNAV system is used to augment the ultraviolet (UV) sensor based satellite navigation system. In order to...
