A new breakthrough could allow scientists to overcome the problems with GPS, according to scientists.

In recent years, positioning technology has become so reliable that it has reshaped the world, allowing people to easily locate themselves using just a small device such as a phone. But that technology continues to face problems, particularly in built-up, busy areas or when indoors.

A new system avoids those problematic satellite signals and instead allows people to locate themselves using phone signals, according to those who have discovered it.
