To improve the receiver’s anti-jamming performance in this harsh scene, a method of vector tracking loop (VTL) based on despread-respread (DR) algorithm is present. Firstly, th

Bias inconsistencies will lead to adverse effects for pseudo-range-based positioning applications and can also hi

This makes spatial adaptive beam-forming incompatible with high precision applications, so the high precision receivers have to be threatened by both intentional and unintentional interferen

In this paper, the method of designing a synthesized correlation function(SCF) based on step-shape code symbol (SCS) is applied to the DET. Anti-multipath performance of DET is improved by introducing the special SCS signal to participate in t

However, the existing anti-spoofing technologies are limited to a specific scenario, which reduces the reliability of receivers greatly. In t

Firstly, the carrier and sign bit code are deprived by delay and multiplication. Then, the Doppler shift of the ranging code is searched. According to the
