    I don't see how anyone can achieve sub-decimeter accuracy with this unless they use something like IGS Final ephemeris and clock data (which requires the user to wait 12-18 days). We are then talking about a STATIC PPP solution; not kinematic (receiver in motion).

    For real-time, kinematic sub-decimeter estimates you will need to measure relative to another receiver with known coordinates – RTK (real-time kinematics).

    Thank you so much for doing this detailed GPS tests it's important to me as I am a Uber driver and I was duped because usually Xiaomi phones really good on GPS I have the notes and A2 also,
    Also UK, US bands are important to me so that's why I thought of getting a better upgrade with Mi8 to replace my Samsung s8 because I love the MIUI and usually expandable storage on Xiaomi,
    Now I feel cheated, I really hope they update software to fix the GPS or its waste of my money for me

    So just to let you know . First the chip is from broadcom . And dual frequency gps is better than single frequency . The software that you are using is not doing taking in consideration the second frenquency that why you don't have a better positioning. If you want to know more about the subject look for gps ambiguity its a integer number that help to determine the distance betwen you and the satellite and correction applied to that distance

    as the gps test is not the best program to check it, I will tell you tomorrow ,when my mi 8 comes. Im using motorola for the moment which is losing signals in small streets in london and ,as we all know, the final result is the important one.

    well… calling it marketing hype just because it's not working currently, you're talking BS, most probably they have some bugs there (or had). I say this because your review was made in june and there is a review from september that compares Mi8 with Garmin GPSMAP 64s and Garmin Oregon 700 on a couple of hikes, and Mi 8 is as accurate as those monsters are (Garmin Fenix 5x did really bad on that trails)
    once again, it's not a marketing gimmik, it's not hype, it's a real thing, and we are waiting for it 🙂

    The city with the buildings is where i would like to see the test.
    These days thats the only location where you have tunnels, towers, over/under etc where the precision would be handy.

    It is not dual frequency GPS retard. Dual frequency GPS means that GPS can receive L1 and L2C frequencies, and then use the L2C to calculate for the ionospheric delay thus giving you superb accuracy. Receiving GPS and Glonass at the same time is not dual frequency, they operate almost at the same frequency, but L1 and L2 are far more different, additionally there is L5C coming soon, anyway, L1 + L2C is the true dual frequency, L1 + SBAS does not qualify to be called dual frequency. But currently the best you can get is L1 + L2C + SBAS, unfortunately you can count availability of small devices that have all those on one hand with few fingers removed Chinese used "dual frequency" like uneducated retards for marketing purposes, and all of you imbeciles took it and ran with it, in their context, "dual frequency" is fucking meaningless, the phone only receives one L1 frequency which is the base frequency of all GNSS satellites from all countries.

    I bought the xiaomi 8 in Hong Kong and sold it a week later. The gps was usually in the range of 4-6 meters and when I tried any GameCube emulator on it, I got very poor frame rates.

    Depends where you live. The closer to the equator the stronger GPS gets (and higher resolution). It gets weaker as you go towards the poles and a 5 metre range is nearly impossible because the satellites are lower on the horizon. That's where locking onto the Russian Glonass system of satellites comes in handy (or even the Chinese ones if your in China) as these are situated closer to the poles than the American GPS system (most people aren't aware that there are three competing GPS systems in place).

    This is where a dual GPS sensor comes in handy as you can lock onto the American GPS satellites and the Glonass system simultaneously and then cross reference between the two. As someone who lives in the U.K i know just how much the American GPS signal drops amongst buildings and trees whereas the Glonass satellites tend to be directly overhead. However, it's a trade off as the Glonass system is lower in resolution (but stronger signal) and the American GPS system is higher in resolution but weaker in signal (in Northern Europe at least).

    Hello, you need to use an application supporting dual frequency Gps signal then you will see the difference. Sorry to tell you the way you tested was not compatible with hardware functionality.

    With the same app and external antenna I get 1,8m. accuracy so it is the phone. The BCM47755 chip was tested view months ago and showed cm. level accuracy (10-30cm.). In Europe it should reach much better accuracy. This result is worst than my 3y.o. Umi Hammer .

  12. Phenoman

    To stand in Xiaomi defense, I also have same reading in that app, but in google maps, it finds me precisely while on my old phone (Moto X Play) it misses a whole street… So maybe the problem is in app? I can definitely see better results on Mi8.

  13. TheHarypeter

    Someone with Xiaomi mi 8 can install a geodetic application like Hi-Q set it to your coordinate system, go to a geodetic point with known coordinates, measure it and compare the coordinates and tell the results. These accuracy apps don't show real accuracy !!!
