New Sub-60cm GPS Accuracy

US Startup Zephyr’s claim that it has solved smartphone GPS positioning problems through a network and software-based solution with sub-60cm accuracy has attracted $3.5 million seed funding. 

The Issue 

Even though consumers have been putting growing demands on GPS through their increasing use of mobile devices and wearables, and many more businesses and services have become more reliant on it, GPS hasn’t had any major updates for more than 20 years, meaning that it is prone to errors, inaccuracy, and can sometimes be unreliable.
