The modern global navigation satellite systems (GNSS) signals, such as the Global Positioning System (GPS) L5 and L1C, and Galileo E5 and E1, have brought several innovations: the introduction of a pilot channel that does not contain any data to allow very long coherent integrations; the introduction of a secondary code to offer better cross-correlations, to facilitate the synchronization with the data, and to help interference mitigation; the introduction of new modulations to reduce the impact of multipath; and the use of higher chipping rates to have better accuracy and interference mitigation.
