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.

It can't come in LG G7 because Samsung will seize the first batch from Broadcom :)

Or Apple, Apple has been using broadcomm chips on their MacBooks pretty much for the the last decade or so now. They have a pretty good relationship I guess.

Time to get a android auto head unit for my car now!! The gps that in the factory head unit is good but this will be a lot better.

Damn, I didn't even think about Android Auto, this would really make the hardware that much better. The first thing that came to mind for me was I can finally find my wife when she disappears while shopping.

Ha! Unfortunately, it will probably still struggle inside buildings, but if your wife goes to a different store, it might pick up on that. On topic, this could be a big deal for auto-driving cars and commercial data collection.

You're such a good husband. I don't bother to look. She'll come back when she needs help carrying something.

I'd rather get to her before she spends too much money on crap we don't need.

LMAO. I hope you don't beat her up when she spends money like that... :))

Oh no, no, no, no, no. I'm a pacifist. I don't raise my hand to other people, but I bitch and complain like nobody's business.

I was planning on getting either the V30 or Pixel XL 2, but now I'm actually thinking about waiting to upgrade until next year now. I use AA in my car, and the GPS can be a little wonky. Although, I could always upgrade now, and again next fall.

Well, what is your current phone?

To comment #10: Yeah I'm planning to get a new phone this year as well but this news makes me tempted to wait. However I'm tired of waiting so I'm pretty sure I'll get one before long.

This is a serious improvement .. Good Job .. Although I would still want GPS to use far less battery than usual (like 5-10x lesser) since more and more apps are now demanding GPS ..

Samsung may not be aware of this news.
