Efficient, dual-frequency GPS chip to vastly increase location accuracy on select phones in 2018
Chip maker Broadcom has just come up with a new dual-frequency GPS chip that promises to greatly improve GPS accuracy - from around 5 meters as of now to roughly 30cm. A great improvement no matter how you look at it.
Currently known as BCM47755, this breakthrough new GPS chip got unveiled a few days ago at teh ION GNSS+ summit in Portland, OR, and has been already included in the blueprints for some unspecified upcoming smartphones. It will be easy to speculate that the Galaxy S9
, S9 Plus and the LG G7 are the prime suspects at the moment.
The big deal with the new chip is that it uses a combination of L1 and L5 GPS signals that make urban positioning that much more accurate than existing solutions and has never before been used in commercial mass-market GPS chips, let alone smartphones. Those two determine the location of the user by measuring how long it takes for a GPS' satellite signal to reach the receiver. Another benefit of L1-L5 signal combo is undisrupted positioning even in densely-built metropolitan areas.
Aside from being vastly more accurate, Broadcom's new GPS chip is also twice as energy-efficient as Broadcom's current GPS solutions, used in many devices, which is easily shaping up to be yet another win for 2018's smartphones.
