   Global Navigation Satellite System (GNSS) receivers, whether in smartphones, cars, or other devices, calculate their position by computing signals from a minimum of four satellites from the available GNSS and regional satellite constellations. [1] The receiver uses the time difference between the broadcast time sent by satellite and the time of ...

   How accurate are phone coordinates?

   • Accuracy is shown to differ based on the manufacturer, the device’s age, and the device’s components. These results are based on the phone coordinates as they follow a jagged path, about 18 meters in total length. Figure 5: Same as figure 3 with accuracy estimation highlighted. 2.

   How accurate is GNSS?

   • As can be seen, the estimated GNSS accuracy by the phones can greatly vary from the true location. The Samsung Galaxy Note 10+ actually undervalues its accuracy by 67.3% while all other phones tested overvalue their accuracy by at least 130%. The iPhone XR overvalued its accuracy by 450%. 3.

   Does GPS drift affect GPS accuracy?

   • During movement, the number of connected satellites is higher, leading to better precision. Conversely, when still, the GPS drift effect disrupts the signal because of environmental factors like buildings, trees, and weather conditions. These hypotheses can be validated in future testing. 5. Longer Paths Offer Greater Accuracy than Acute Ones
