For example, GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius under open sky (view source at ION.org). However, their accuracy worsens near buildings, bridges, and trees. High-end users boost GPS accuracy with dual-frequency receivers and/or augmentation systems.
Then, how accurate are GPS receivers on average?
GPS receivers are accurate to within 15 meters (49 feet) on average. Certain atmospheric factors and other sources of error can affect the accuracy. Accuracy can be improved with a Differential GPS (DGPS) or WAAS (Wide Area Augmentation System).
Furthermore, can a GPS receiver be detected? GPS Bug Detectors use the radio frequency signal that is sent by a GPS Tracker to “detect†a GPS device. So it “confirms the presence†of radio signals being transmitted by the device to the cellular networks used to communicate status and location with.
In this manner, how accurate is GPS positioning?

How does a GPS receiver determine its exact location?
A GPS receiver determines its own location by measuring the time it takes for a signal to arrive at its location from at least four satellites. Because radio waves travel at a constant speed, the receiver can use the time measurements to calculate its distance from each satellite.
