Spacecraft could one day navigate throughout the space using a exacting type of dead star as a type of GPS.According to Prof Werner Becker from the Max-Planck Institute for outer space Physics in Garching the standard is so simple that it will definitely have applications. These pulsars are everywhere in the Universe and their flashing is so unsurprising that it makes such an approach really as simple.
The future technique is much related to that working in the popular Global Positioning System, which broadcasts timing signals to the user from a constellation of satellites in orbit. Still for a probe at the reasonably short division of Mars, the positioning doubt can be about 10km. It is also a technique that is far from precise, and the errors increase the further away the probe moves.
