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.
