Feature article: High sensitivity acquisition of GNSS signals with secondary code on FPGAs
2017
IEEE Aerospace and Electronic Systems Magazine
The presence of a secondary code in modern global navigation satellite system signals complicates the acquisition of these signals, because there is a potential sign transition between each period of the primary code. Some previous works proposed to use the parallel code search by performing the correlation over the primary code several times and then combining the results according to the secondary code chips. In this article, we will focus on this method and compare different hardware
