Highlights of the pulsar test satellite XPNAV-1

• This X-ray pulsar navigation satellite weighs more than 200 kilogrammes.
• It operates in a Sun-synchronous orbit and will conduct in-orbit experiments using pulsar detectors to demonstrate new technologies.
• While in orbit, the satellite will undergo tests on its detector functions and space environment adaptability.
• The periodic X-ray signals emitted from pulsars will be used to determine the location of a spacecraft in deep space.
• The X-ray pulsar navigation will help reduce the spacecraft’s reliance on ground-based navigation methods and is expected to lead to autonomous spacecraft navigation in the future.
