![]() ![]() Many things can degrade GPS positioning accuracy. Why does GPS sometimes show me in the wrong place? Recent FAA data shows their high quality, single-frequency GPS receivers attaining horizontal accuracy of ≤1.82 m (5.97 ft.), 95% of the time. These can enable real-time positioning within a few centimeters, and long-term measurements at the millimeter level. High-end users boost GPS accuracy with dual-frequency receivers and/or augmentation systems. However, their accuracy worsens near buildings, bridges, and trees. GPS satellites broadcast their signals in space with a certain accuracy, but what you receive depends on additional factors, including satellite geometry, signal blockage, atmospheric conditions, and receiver design features/quality.įor example, GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius under open sky ( view source at ION.org). ![]() Doesn't the government degrade civilian GPS accuracy?.Is military GPS more accurate than civilian GPS?.How accurate is GPS for speed measurement?.What is the government's commitment to GPS accuracy?.Why does GPS sometimes show me in the wrong place?. ![]()
