Many people depend on GPS (International Positioning System) to estimate journey instances, discover our method to new locations, keep away from visitors congestion, preserve observe of the youngsters, and usually keep away from getting misplaced.

However it’s not all the time probably the most dependable of methods, particularly in built-up areas the place it is troublesome to get a straight line of sight to and from a satellite tv for pc.

Now researchers have give you a brand new and improved expertise that would ultimately change GPS in some eventualities. Referred to as SuperGPS, it is correct inside 10 centimeters (or 3.9 inches) and does not depend on navigation satellite tv for pc methods.

The brand new strategy makes use of networks much like cell networks, however as a substitute of streaming knowledge to our telephones the community will get a exact repair on the system.

A mixture of radio transmitters and fiber-optic networks type the muse of the system, with some good tweaks on prime.

“We realized that with a couple of cutting-edge improvements, the telecommunication community may very well be reworked into a really correct different positioning system that’s unbiased of GPS,” says physicist Jeroen Koelemeij from Vrije Universiteit Amsterdam within the Netherlands.

“We’ve succeeded and have efficiently developed a system that may present connectivity identical to current cellular and Wi-Fi networks do, in addition to correct positioning and time distribution like GPS.”

In a take a look at website with six radio transmitters, the researchers had been capable of reveal their system in motion throughout an space of 660 sq. meters (7,104 sq. toes). The timings of the transmitted radio alerts may be measured and interpreted to gauge distance, which then reveals the place of particular person units.

One of many key elements of the brand new community positioing system is a synchronized atomic clock: good timing means extra exact positioning. Primarily, the fiber optic cables act as connections that preserve all the things in sync, and correct to 1 billionth of a second.

The system additionally deploys a radio sign bandwidth that is a lot bigger than regular – though as radio spectrum bandwidth is dear as a consequence of its shortage, the workforce used a number of small bandwidth radio alerts mixed collectively to type a bigger digital bandwidth for the community communication.

This extra bandwidth overcomes one of many largest issues with normal GPS, which is that radio alerts get mirrored off buildings and might rapidly develop into confused.

“This could make GPS unreliable in city settings, as an illustration, which is an issue if we ever wish to use automated automobiles,” says electrical engineer Christiaan Tiberius, from the Delft College of Expertise within the Netherlands.

In addition to automated automobiles, the brand new system may very well be helpful in planning quantum communication networks and next-generation networks for cellular units, in line with the researchers who developed it.

Whereas International Navigation Satellite tv for pc Techniques (GNSS) together with GPS definitely have their makes use of and can proceed to take action for a very long time to come back, specialists are regularly on the lookout for methods to enhance and refine it.

Extra testing goes to be required to determine this as a real different to GPS. The proposed network-based system would additionally take time to arrange, despite the actual fact its transmission protocols and {hardware} are already in use. Present cellular and Wi-Fi masts may very well be tailored for the job not less than, in line with the researchers.

“This work gives a glimpse of a future wherein telecommunication networks present not solely connectivity but additionally GNSS-independent timing and positioning providers with unprecedented accuracy and reliability,” the researchers state of their printed paper.

The analysis has been printed in Nature.
