What is the function of CORS in GPS systems?

CORS, which stands for Continuously Operating Reference Stations, plays a crucial role in enhancing the accuracy of GPS data, particularly for precise positioning. The primary function of CORS is to provide a network of stationary GPS receivers that continuously collect and broadcast GPS signals. This network allows for post-processing of GPS data, improving its accuracy by correcting for errors caused by various factors such as atmospheric conditions, satellite orbit errors, and signal multipath effects.

When GPS devices collect data, especially in applications requiring high precision, the signals can be affected by inaccuracies. By utilizing data from CORS networks, users can apply correction factors to their GPS data, leading to much more accurate localization. This process is essential in fields such as surveying, agriculture, and geodesy, where precise positioning is fundamental.

The other options, while related to GPS technology, do not accurately represent the primary function of CORS. Generating accurate real-time locations is more related to the capabilities of the GPS system itself rather than the specific role of CORS. Increasing satellite signal frequency is not within the scope of CORS functionality, as this pertains more to satellite technology and capabilities. Regulating GPS device accuracy also does not describe CORS accurately, as it is focused on providing support rather than
