Scientists have developed a GPS laser replacement

Scientists from the Emergent Photonics Lab (EPic Lab) at the University of Sussex used atomic clocks as a GPS replacement based on laser radiation.

In modern smartphones and other navigation devices used satellite systems GPS and GLONASS. This means that users are constantly dependent on the vagaries of international satellite signal availability policy. It seems that now there is a universal solution to this problem.

The developers assume that their technology will change people's daily lives and will be used in automobiles, unmanned aerial vehicles, as well as in the aerospace industry. Light impulses enclosed in a tiny chip are used in portable atomic clocks under development. This is reminiscent of the way fiber optic internet cables work.

Atomic clocks can be used in many areas. For example, an ambulance will be able to use the positioning system, even while in a tunnel, and ordinary users will plan a route while being in the subway or in another place where there is no cellular signal. However, with the integration of the new positioning system, you will most likely have to wait.
