Broadcom Limited just announced a new dual-frequency GPS solution that promises accuracy up to 30cm. As a comparison, previous generation GPS systems are only accurate up to 5 metres.
The chip which is called BCM47755 was announced recently at the ION GNSS+ summit in the United States. What makes this chip vastly more accurate is that it uses a combination of L1 and L5 GPS signals in a single chip which has never been done before, even in commercial applications.
Another benefit of using this combination is better detection, even in densely populated cities. At the same time, the new chip will be more power efficient when compared to Broadcom’s current offerings – translating to better battery usage in the long run.

Several manufacturers apparently will be implementing this chip in their 2018 flagship smartphones. No names were mentioned, but we can foresee names like Samsung, LG and the like will have this chip in their chart-topping phones for next year.
Will this new GPS chip help with better traffic routing in Waze and Google Maps? We will have to wait and see in 2018 when it rolls out by then.
