Positsioneerimistäpsus refers to the accuracy of a device's or system's ability to determine its geographical location. This concept is crucial in various applications, including navigation, mapping, surveying, and location-based services. The precision of a positioning system is typically measured in meters or even centimeters, depending on the technology used and the required level of accuracy.

Several factors influence positioning accuracy. The most common technology, Global Navigation Satellite Systems (GNSS) like GPS, relies on signals from satellites. The quality of these signals, the number of visible satellites, atmospheric conditions, and the presence of obstructions (such as tall buildings or dense foliage) can all affect the accuracy of the determined position. Multi-path effects, where signals bounce off surfaces before reaching the receiver, can also introduce errors.

Different positioning technologies offer varying levels of accuracy. Standard GPS receivers might achieve accuracy within a few meters. More advanced techniques, such as differential GPS (DGPS) or Real-Time Kinematic (RTK) GNSS, use ground-based reference stations to correct for errors and can achieve centimeter-level accuracy, essential for surveying and precision agriculture. Other positioning methods include Wi-Fi triangulation, cell tower triangulation, and inertial navigation systems, each with its own accuracy limitations and use cases. Understanding the specific requirements of an application is key to selecting an appropriate positioning technology and interpreting its accuracy.
