What kind of accuracy does satellite-based navigation typically provide?

Satellite-based navigation systems, such as GPS, are designed to provide highly accurate positional information. The typical accuracy achieved by these systems is within a few meters under optimal conditions. This level of accuracy is made possible by the multiple satellites that triangulate a user's position, allowing for precision in navigation that is essential for various applications in aviation, maritime, and personal navigation.

In practical terms, this accuracy means that when using a modern GPS receiver, a user can ascertain their location to within a few meters, which is critical for safe and effective navigation, particularly in aviation where precise positioning is necessary for flight safety and efficiency. Factors such as satellite geometry, atmospheric conditions, and multi-path effects can influence this accuracy, but the standard expectation remains within a few meters in a well-functioning system.
