Dual-frequency GPS
Dual-frequency GPS uses two different signals from satellites, transmitted at separate frequencies, to improve position accuracy. By receiving these two signals, GPS devices can better identify and correct errors caused by atmospheric conditions, particularly the ionosphere, which can distort signals. This results in more precise location data, especially important for applications like surveying, navigation in challenging environments, and autonomous vehicles. Essentially, dual-frequency GPS provides a clearer, more reliable fix on your position by comparing and correcting the differences between the two signals.
