X-ray pulsar based navigation
- X-ray pulsar based navigation
X-ray Pulsar-based Navigation and Timing (XNAV) is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a spacecraft in deep space. A spacecraft using XNAV compares received X-ray signals with a database of known pulsar frequencies and locations. Similar to GPS, this comparison allows the spacecraft to triangulate its position accurately.
