For example, GPS-enabled smartphones are typically accurate to within a 4. These can enable real-time positioning within a few centimeters, and long-term measurements at the millimeter level.
But with raw GNSS measurements from the phones, this can now improve, and with changes in satellite and receiver hardware, the improvements can be dramatic. The following phones have been tested.
