Feature article: High sensitivity acquisition of GNSS signals with secondary code on FPGAs
IEEE Aerospace and Electronic Systems Magazine（2017）
摘要
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...
