The X-ray Navigation (XNAV) technology, also known as The Station Explorer for X-ray Timing and Navigation Technology (SEXTANT), is an innovative NASA mission that leverages X-ray pulsars for spacecraft navigation. Launched as a demonstration, XNAV aims to advance spacecraft navigation methods by utilizing the precise timing signals emitted by X-ray pulsars.
X-ray pulsars are highly magnetized, rotating neutron stars that emit regular and extremely precise X-ray pulses. By measuring the arrival times of these pulses, XNAV enables spacecraft to determine their position and velocity with remarkable accuracy.
This pioneering technology has the potential to significantly enhance space navigation for future missions, allowing for autonomous and precise navigation over vast distances within our solar system and beyond.
