Apple Granted Patent for System With Wireless Messages To Enhance Location Accuracy

Apple Address Weakness Characteristic in GPS Based Navigation System

In a patent granted to Apple, the company imagines complete cities outfitted with low-power wireless transmitters capable of sending pinpoint precise location data as well as dynamic environmental alerts, to iPhones and in-car navigation systems. As issued by the U.S. Patent and Trademark Office, the U.S. Patent of Apple, tends to continue the investigation into beacon-based navigation of the company though on a grand scale. Rather than aiding iPhone owners in locating car that may be parked in an underground lot or locate their position utilising advanced geo-fencing algorithms, the latest invention of Apple tends to address weakness characteristic in all GPS –based navigation systems.

The present patent endeavours to resolve reception issue which come up in thickly inhabited cities, at times referred as urban canyon environments for their elevated buildings while simultaneously increasing the granularity of positioning data. Essentially, the solution of Apple tends to consume less power than A-GPS, Wi-Fi positioning as well as cellular tower triangulation procedures, all present augmentation to vanilla GPS.The plan calls for a multitude of stationary transmitters to be installed at strategic locations next in the vicinity of the city roads, like adjacent building, within pre-existing traffic lights, guard rails, roadside signs together with other structures.

Transmitter – A Smart Wireless Hub

Every transmitter is mostly a smart wireless hub rising with radio transceivers, which is a perfect configuration support cellular, Bluetooth Low Energy, Wi-Fi and GPS data transfer proprieties and the equipment can be fed by AC line power or solar system.A stationary waypoint device, in operation broadcasts its location data, plotted on a Cartesian plane through wireless Bluetooth LE message.

Each message is sent at known signal strength enabling the receiving device such as iPhone or car to induce relative location built on received signal strength indicator – RSS value. The receiving device could utilise various techniques in determining its total position based on the number as well as quality of the messages received, with two choices comprising of triangulation together with time-of-flight computations. In some examples, an iPhone could utilise location data provided by static devices in performance with GPS details though the invention of Apple has the capability of operating as a locked system.

Apple’s Invention – A Role in Autonomous Vehicle Logic

As an addition, the transmitters could also send out z-axis data to be used on multi-level highways for instance, a measurement which is regularly available from commercial GPS system. With regards to navigation, the system can be organised in tracking vehicle movement with great degree of precision. A series of transmitters for instance, could be installed along off-ramps and on-ramps, forks in a road, freeway exits as well as other locations where the traditional GPS system tends to fail in resolving user position with sufficient accuracy.

Though it has not been mentioned in the recent document, the invention of Apple could play a role in autonomous vehicle logic and the described transmitters in particular could be shaped to broadcast rich data comprising of information with regards to traffic, road as well as other driving conditions. User for instance could be informed of an upcoming speed limit change, rough weather, and risky road condition while driving past a connected transmitter.

With the prevailing car equipment, these messages could present an audible alert and an onscreen dialogue. In future, nevertheless, the same roadside beacon could inform an on-board AI of the neighbouring atmosphere warning it to take action when necessary.
