Google will improve GPS accuracy of Android mobiles by up to 75%



Knowing the exact point of the map we're on, including the sidewalk we're walking on, Google announces that the GPS accuracy of Android mobiles will improve by 2021.

When we check Google Maps, we usually see clearly on the street where we are, but it is not possible to specify the exact height, the sidewalk we are on or if we are inside one of the buildings. The accuracy of our mobiles in this regard leaves a lot to be desired.

Google wants to change this problem and improve the GPS accuracy of all mobiles that use its Android operating system. In its statement, the company explains that with the changes it plans, by 2021 the accuracy in those applications will be 75% higher.

It is normal that in urban areas GPS data will be altered, as can be seen in the image above, the GPS signal reaches our phone reflecting against the buildings. This system ends up causing the location success rate to be very low and usually fails. To remedy this, Google proposes to collect 3D information from a city's distribution.

This technology has been useful for some time on Pixel 5 and Pixel 4a 5G mobiles. Your goal is to create a 3D map of all corners of the planet with information that has been collected with Google Maps and other projects. This 3D map of cities will give you the key to knowing which buildings the GPS signal is reflecting in and more accurately set the height at which we are.

With this improvement, the maps will better tell us where a bus stop or shop is located without having to go around the street because their position on the map has deviated several numbers. If we meet a person and share our location, it will be easier for them to locate us at the height and side of the street we are on. No more spinning down the street calling the other person to find out which portal you're on because Google mix marks the place.



This accuracy is much clearer in the example Google shared on its developer blog. The red lines are those that recorded the GPS with the previous technological model and worse accuracy, while the new model would be the blue line whose results come closer to the original route in yellow.

From Android 8 onwards, all mobiles that integrate these versions of Google's operating system will end up receiving this improvement throughout 2021. After testing it on the latest Pixels, the API is available to developers of other applications that can take advantage of this technology. Navigators like Waze could further hit the road we're driving on, even differentiate between lanes.

But to bring all those improvements, Google must first study the 3D maps of our cities. The company has begun to study the relief and distribution of all major cities in Europe, the United States, Canada, Mexico, Japan, Taiwan, Argentina, Brazil, Australia, New Zealand and South Africa. Over time this technology will expand to other areas.
