GPS Accuracy

GPS accuracy refers to how close the reported position is to the actual location, typically measured in meters.

What is GPS Accuracy?

Standard GPS accuracy is typically 3-5 meters under clear sky conditions. Accuracy can be affected by tall buildings (urban canyons), dense foliage, tunnels, and atmospheric conditions. Modern GPS trackers often use multiple satellite systems (GPS, GLONASS, Galileo) to improve accuracy and reduce the time needed to acquire a position fix.

Key facts

  • Precise vehicle location for dispatching
  • Accurate mileage tracking for billing
  • Reliable geofence boundary detection
  • Better route optimization

Frequently Asked Questions

Yes, using trackers with multi-constellation support (GPS + GLONASS + Galileo), ensuring clear sky visibility, and using trackers with external antennas can improve accuracy.
GPS position drift can occur when the vehicle is stationary due to signal reflections and atmospheric variations. Quality tracking platforms filter this noise to show stable positions.
