What is the primary function of GNSS error correction?

The primary function of GNSS error correction is to improve the accuracy of positioning. GNSS, or Global Navigation Satellite System, provides position information based on signals received from satellites. However, various sources of errors, such as atmospheric conditions, satellite clock inaccuracies, and multipath effects, can impact the precision of the positioning data.

Error correction techniques, such as differential GNSS (DGNSS) or satellite-based augmentation systems (SBAS), are designed specifically to reduce these errors and enhance the overall accuracy of the calculated position. By applying these corrections, users can achieve a much more precise location fix, which is crucial for applications requiring high accuracy, such as aviation, maritime navigation, and surveying.

The other choices focus on different aspects that do not inherently relate to the fundamental goal of GNSS error correction. Calibrating devices, increasing reception range, and simplifying user interfaces do not directly address the necessity of enhancing the accuracy of the positioning information that GNSS provides.
