    At least one smartphone has the new Broadcom BCM47755 chip, which enables 1-foot accuracy. Does anyone know if Garmin plans to introduce new models with similar accuracy?

    If not, it would be difficult for them to sell any of their handheld models with 3-5 m accuracy, when smartphones have 1-foot accuracy.

    I too would be very interested to know the answer to your question, what I can say is that dedicated GNSS manufacturers seem to be much slower to the market place than cell phone manufacturers, I think they would claim to do more testing on a GNSS only product, than cell phone phones that have many different functions.

    I guess the smartphone you are referring to is the Xiaomi Mi 8, with some listings showing the BCM47755, the Mi 8 is commonly shown to have a dual band GPS with L1 & L5 capability, here are some info. links for the Mi 8:-

    Thanks Nuvi-Nebie. Yep that's the smartphone model I was referring to.

    I'm going to keep an eye on what Garmin does, because I just can't see them selling a lot of handheld GNSS receivers if they have to compete with smartphones that incorporate that 47755 chip. I'm sure Garmin has already lost a ton of GNSS receiver sales to smartphones, and if smartphones get this 1-foot accuracy before Garmin devices do, that'll make Garmin devices obsolete to most consumers.

    Even though I have a Garmin Montana, I frequently use my smartphone instead, because it's faster, has a nicer & bigger display, better touch-screen, etc.

    I hope Garmin still thinks there's a market for their handheld receivers, and steps up with a new product line really quickly.

    I mention only Garmin because that's the brand of receiver I have, but the same applies to Magellan and the others too.

    I would agree, Garmin, Magellan etc, still have a few advantages over cell phone manufacturers, e.g. waterproof housings, longer battery life, more stable operating systems and daylight readable displays, but, cell phones already have better GNSS chips providing a greater number of satellite constallaions, much better screens resolutions / sizes and the availability of mulititudes of Apps. that can be programmed to use the GNSS signals in many more different ways than dedicated 'GPSs'

    When you add 1-foot accuracy (something only achieved with dedicated units costing thousands of Dollars / Pounds) to the mix, it makes handheld and satnav units look like a very poor alternative to the cell-phone that virtually everyone already owns - So come on Garmin, Magellan etc. Give us a dual band GNSS soon ! ! !

    So Garmin chose to go with a Sony chipset for their new watches (2019). From what I've read and the pictures I've seen of users showing their mapped runs the accuracy and consistency is worse than before. But battery life is better, I think.

    I've had a couple of GPS watches. In order of accuracy the SirfStar chipset was the best so far (older Garmins and my current TomTom Multisport), then the MediaTek (Forerunner 230 / 630, etc) and from what I've seen Sony is last on the list. I actually chose to keep the TomTom which has less features than the Garmin because the GPS tracked better. It would have been nice if Garmin went with the Broadcom chipset and improved their accuracy.
