What is the typical accuracy range of a GPS positioning?

The typical accuracy range of GPS positioning is generally recognized to be around 10 meters under normal conditions. Various factors, such as atmospheric conditions, satellite geometry, and signal blockage, can affect this accuracy. Most consumer-grade GPS receivers fall within this range, providing a good enough precision for navigation and general use.

GPS technology can achieve higher accuracy in specialized applications. For instance, differential GPS (DGPS) can provide accuracies down to a few centimeters, but this involves additional infrastructure and is not the typical performance level of standard GPS systems used by the majority of boaters and general users. The other options, while they may represent potential accuracies in different contexts or advanced systems, do not accurately reflect the typical performance of standard GPS technology commonly in use.
