We were all there using Google Maps for navigation and waiting for the app to find our location. As we drive around, we continue to hope that there will be a lock in time for the next turn. Well, in the US, we finally have a solution to this problem and it is the OnePlus 7 Pro.
The OnePlus 7 Pro is the first US phone to feature dual-frequency GNSS (sometimes referred to as dual-band GPS). With this new technology, the 7 Pro can pinpoint your location on the track not just on the road. This technology has been available since 2017 and has found its way into a handful of phones, none of which has been released in the US. But with the OnePlus 7 Pro, Americans can now benefit from the precise tracking of two-frequency GNSS on a phone that is even $ 300 cheaper than most flagships.
What exactly is two-frequency GNSS?
As you know, your phone can track your position using GNSS (Global Navigation Satellite Systems). In the US, this is synonymous with GPS.
Most existing phones use a single-frequency GNSS. With a single radio signal, your phone is tracked by satellite and determines your position for all areas, from navigation to e-commerce apps. While a single signal in an open area works well, it can be reflected off large objects such as buildings. The result of this jumping is a drop in positional accuracy, which can be as much as 5 m (1
As the name implies, this problem is solved by the double frequency radio signals. Instead of a single radio frequency, your phone uses two. If the accuracy drops due to interference on a frequency, there is a reserve frequency to maintain a stable connection to the satellite.
With this increased reliability, dual-frequency phones can track your position within a 30-cm radius) relative to your actual position, which translates into turn-by-turn directions, knowing exactly where you are in the particular lane you're driving , This results in fewer errors and less time spent recalculating the route of your navigation app.  GNSS is currently available with two frequencies for three satellite navigation systems: GPS, Galileo and QZSS. GPS is a system developed and maintained by the United States Government and used primarily for travel in America. Phones that support two frequencies for GPS would use L1 and L5 signals.
Galileo is the European Union version and works throughout Europe. It uses E1 and E5 at dual frequency. QZSS (or Quasi-Zenith Satellite System ) covers Japan and the Asia-Oceania region at double frequency with L1 + L5.
Android has introduced official support for Dual Frequency GNSS in Android 8.0 Oreo. Companies such as Broadcom even launched a dual-frequency chip (BCM47755) in 2017 that supports all three dual-frequency satellite navigation systems. While Broadcom stated that their chip would be used for smartphones in 2018, none of these phones were approved in the US.
Until OnePlus announced the 7 Pro, the only phones to support GNSS with two frequencies were the Xiaomi Mi 8, Xiaomi Mi Mix 3, Huawei Mate 20, Mate 20 Pro, Mate 20 X, Mate 20 RS, P30 and P30 Pro. Although you can buy the Huawei P30 series from B & H, this is the international version, which means it lacks a US warranty. Now the Americans have their first real option in OnePlus 7 Pro. The OnePlus 7 Pro supports both GPS L1 + L5 and Galileo E1 + E5, making it the first US phone to do so. There is no QZSS support for two frequencies (the QZSS navigation system is not supported at all), but usually this GNSS is not found in Android-based smartphones that are on the market in the US anyway.
All this means users are traveling. In the US and Europe, you do not have to worry about cities and large buildings compromising navigation accuracy as the phone tracks them closely throughout their journey. The OnePlus 7 Pro also supports most other major satellite navigation systems, including GLONASS and BeiDou, to make sure your phone can locate you wherever you are.
If you consider everything that the OnePlus 7 Pro is offering, how can you look elsewhere? With up to 12GB of RAM, 256GB of memory, a Qualcomm Snapdragon 855 SoC, the 90Hz 6.67 QHD + Fluid AMOLED display, and a $ 669 MSRP, there's simply no phone that's value for money corresponds. And since it offers something that no other US smartphone in dual-frequency GNSS offers, it offers even more value.
