“…They used the method of fast Fourier transform to detect the doublet and extract the Doppler difference of the doublet. In addition, they derived the relative velocity residual based on the Doppler difference through the above process, and compared it with the corresponding threshold to determine whether it was spoofed [60]. The analysis and summary for the spoofing detection methods based on Doppler shift is shown in Table VIII.…”

A large number of facts prove that Global Navigation Satellite System (GNSS) has certain security risks and is threatened by attacks. In particular, GNSS civilian signal receivers have some vulnerability in responding to spoofing attack and jamming attack, because the format and modulation of GNSS civilian signals are public. Based on the concerns of existing GNSS spoofing scenarios, this paper reviews the research on GNSS anti-spoofing technologies from two aspects. In this paper, the strategies of spoofing attacks discovered at this stage are classified in detail, the protection effect and scheme implementation complexity of various anti-spoofing techniques against spoofing attacks are analyzed from the perspective of signal-level and data-level. More specifically, we comprehensively analyze the ability for the combined anti-spoofing methods at the signal-level and the data-level to protect from combinations of different spoofing attack. Finally, the future development trend and potential research direction of GNSS anti-spoofing technology are summarized and predicted.

“…A typical synchronous spoofing intrusion process includes scenarios such as initial synchronization, power increasing, and code phase pull-off [1], [4]. In the real world, inevitable synchronization errors, variations in the SSR, code phase and carrier phase of the spoofing signal, and the target receiver settings impact the spoofing success rate [7], especially when appropriate antispoofing signal processing methods are employed by the target receiver.…”

A synchronous GNSS generator spoofer aims at directly taking over the tracking loops of the receiver with the lowest possible spoofing to signal ratio (SSR) without forcing it to lose lock. This paper investigates the factors that affect spoofing success and their relationships. The necessary conditions for successful spoofing are obtained by deriving the code tracking error in the presence of spoofing and analyzing the effects of SSR, spoofing synchronization errors, and receiver settings on the S-curve ambiguity and code tracking trajectory. The minimum SSRs for a successful spoofing calculated from the theoretical formulation agree with Monte Carlo simulations at digital intermediate frequency signal level within 1 dB when the spoofer pulls the code phase in the same direction as the code phase synchronization error, and the required SSRs can be much lower when pulling in the opposite direction. The maximum spoofing code phase error for a successful spoofing is tested by using TEXBAT datasets, which coincides with the theoretical results within 0.1 chip. This study reveals the mechanism of covert spoofing and can play a constructive role in the future development of spoofing and anti-spoofing methods.
