The average best would be
15 meters
and the average worse close to 30-40 meters. The results stated above are from my own field work and come from using various types of smartphones. GPS accuracy greatly varies depending on surroundings, devices used, weather and many other factors.
What is the average accuracy of GPS?
How accurate is GPS for speed measurement? As with positioning, the speed accuracy of GPS depends on many factors. The government provides the GPS signal in space with a global average user range rate error (URRE) of
≤0.006 m/sec over any 3-second interval
, with 95% probability.
What is a good GPS signal strength?
The typical power level of the GPS signal is
-125 dBm
.
What is high accuracy GPS?
A high-accuracy GPS receiver
precisely calculates geographic locations using information from GPS satellites
. … GPS satellite signals are transmitted on different frequencies. The more frequencies that the GPS receiver uses—and, consequently, the more signals it receives—the more accurate it is.
How accurate is the best GPS?
Ultimately, most GPS tracking devices are
accurate to within three meters
, allowing users to have fairly accurate location information. While operating in low-accuracy areas can negatively affect your results, GPS tracking technology has evolved to ensure stronger signals and greater accuracy.

What is the minimum accuracy of GPS?
The United States government currently claims
4 meter RMS (7.8 meter 95% Confidence Interval)
horizontal accuracy for civilian (SPS) GPS. Vertical accuracy is worse. Mind you, that’s the minimum. Some devices/locations reliably (95% of the time or better) can get 3 meter accuracy.
Why is GPS not accurate?
GPS: Maps uses satellites to
know
your location up to around 20 meters. When you’re inside buildings or underground, the GPS is sometimes inaccurate. Wi-Fi: The location of nearby Wi-Fi networks helps Maps know where you are. Cell tower: Your connection to mobile data can be accurate up to a few thousand meters.

How accurate is WAAS GPS?
Using WAAS, GPS signal accuracy is improved from
20 meters to approximately 1.5 – 2 meters
in both the horizontal and vertical dimensions.
How accurate is Galileo GPS?
The Galileo system has a greater accuracy than GPS, having an
accuracy of less than one metre
when using broadcast ephemeris (GPS: three metres) and a signal-in-space ranging error (SISRE) 1.6 cm (GPS: 2.3 cm, GLONASS and BeiDou: 4–6 cm) when using real-time corrections for satellite orbits and clocks.
How accurate is phone tracking?
Based on an independent third party study, the reality is that on average,
location data obtained via mobile smartphones is accurate up to 30 meters
.
Can GPS be wrong?
As you can see,
GPS Trackers can report the wrong information
, but this is generally due to a poor install. When installing a GPS tracker, keep in mind that it needs a clear view of the sky to give you the most accurate information.
How do I know if my GPS is accurate?
Determine the positions of these points with your GPS:
Fasten the device motionless for at least one minute at each point
. Repeat the measurement ten times in the interval of at least 90 minutes to have different satellite constellations and possibly different atmospharical conditions.
Can GPS speed be wrong?
With a clear view of the sky, GPS speed has
shown to be more accurate than
most vehicle speedometers. … Your vehicle speedometer accuracy can vary based on several factors, most notably differences in wheel size due to wear, pressure, and temperature.
