NASA Galaxy Positioning System May Lead To A True Autonomous Spacecraft
Nov 23, 2018

NASA scientists built a "Galaxy Positioning System" using Pulsar's perfect "timed" X-ray flash, which works in much the same way as global positioning systems around the world. NASA will dispatch an unmanned spacecraft to shoot distant planets or the moon in a manner similar to pointing a rifle at the sky and firing bullets.


NASA developed its new method, the Galaxy Positioning System, using the neutron star inside the International Space Station to form a detector telescope. It uses this special telescope to observe the fog radiation through space. The 'fog' around the pulsar 'pulse' has a tiny 'flicker' that can be measured based on the amount of time between them, about 4 milliseconds. By comparing the differences in measurements between three different pulsar points, the spacecraft can determine its relative position (it uses the fourth to calibrate the other three times).


NASA scientist Zaven Arzoumanian said: You can get into a orbit around a distant planet by completing a difficult job, instead of doing a fly. The galaxy positioning system can also provide a backup so that if an occupant mission loses contact with the Earth, they still have an autonomous navigation system.

 

This system can make Mars manned space flight a reality and even pave the way for the task of continuing to explore the galaxy.
