Dual-frequency positioning

Dual-frequency positioning is a method used in navigation systems, such as GPS, to increase accuracy. It utilizes signals transmitted at two different frequencies. By comparing the time it takes for signals at each frequency to reach a receiver, the system can correct errors caused by factors like atmospheric interference. This results in more precise location determination. Essentially, dual-frequency positioning enhances the reliability and accuracy of navigation, making it particularly useful for applications requiring high precision, such as in aviation, surveying, and autonomous vehicles.
