“…We examined the case of a single-antenna receiver. Multiple antennas may still be employed, for example, to enhance the performance or security of the scheme by, e.g., checking the angle of arrival of a GNSS signal [14,15]. A representation of the considered scenario is depicted in Figure 1.…”

*gnss provide accurate positioning and timing services in a large gamut of sectors, including financial institutions, Industry 4.0, and *iot. Any industrial system involving multiple devices interacting and/or coordinating their functionalities needs accurate, dependable, and trustworthy time synchronization, which can be obtained by using authenticated *gnss signals. However, *gnss vulnerabilities to time-spoofing attacks may cause security issues for their applications. Galileo is currently developing new services aimed at providing increased security and robustness against attacks, such as the *osnma and *cas. In this paper, we propose a robust and secure timing protocol that is independent of external time sources, and solely relies on *acas and *osnma features. We analyze the performance of the proposed timing protocol and discuss its security level in relation to malicious attacks. Lastly, experimental tests were conducted to validate the proposed protocol.

“…Then, a sequential de-spoofing method is developed to remove fake signals from raw digital samples. In [83], a hybrid algorithm for dealing with interference and spoofing based on antenna array is presented. In this algorithm, the jamming is removed by subspace projection, and then a compact sensing framework is used to extract the navigation signal and identify the spoofing signal.…”

Global navigation satellite systems (GNSS) have played an important role in commercial, military and industrial navigation as well as cloud computing, geospatial analysis and digital modeling. Nowadays, with the advancement of science and technology, the capabilities of electronic warfare, including signal jamming, interference, and spoofing, have also advanced. Attacks and threats at simple, intermediate and advanced levels, endanger the security and reliability of GNSS in the commercial, industrial and military fields such as geolocation, geospatial techniques and digital twins. Therefore, coping with this problem and challenge is very important in maintaining security and reliability. At present, various methods and algorithms have been designed and utilized based on statistical properties, moving receiver, artificial array, wavelet transform and etc., each of which has advantages, disadvantages and blind spots. In this paper, the necessity and requirements for dealing with GNSS threats are emphasized, and the most important researches in the field of GNSS threat (jamming/interference/spoofing) detection and mitigation are studied and reviewed. Their advantages and disadvantages are discussed, and improving areas are also proposed.

“…Authors in [53] proposed a GNSS jamming and spoofing suppression algorithm based on multiple antennas but it suffered from high calculation costs. Authors in [39] proposed a computationally non intensive method. It projects the received signals in the orthogonal subspace of the jamming followed by compressed sensing to detect any interference.…”

GPS (Global Positioning System) plays a big role in day to day activities. From navigation to tracking devices, all are dependent on GPS. As the attacks on GPS have increased so the review of GPS security plays a vital role in research. This paper looks at different spoofing generation methods. The idea is to discuss the single antenna, multiple antenna and other factors that are susceptible to interference. Based on the type of vulnerability the solutions are described in detail. This paper focusses on the current anti-jamming and anti-spoofing GPS mechanisms. This paper presents a comprehensive analysis of all the techniques along with the pros and cons of each method.
