“…Vulnerabilities because of The adoption of a broadcast communication mode in Global Navigation Satellite Systems (GNSS) is designed for user convenience, where navigation signals are directly broadcast to the majority of users [26]. However, this approach exposes the communication channel to potential vulnerabilities due to its direct exposure in the social space.…”

In the contemporary landscape dominated by widespread Global Navigation Satellite Systems (GNSS) usage for various navigational applications across aerial and terrestrial domains, route determination efficiency is increasingly reliant on the accuracy of inputs derived from GNSS, primarily facilitated by GPS and associated modules. However, the rising occurrence of spoofing mechanisms has introduced distortions in this realm, necessitating thorough examination. The discernible impact of GNSS signals on seamless navigation underscores their pivotal role in precise path determination. Yet, sophisticated spoofing methodologies disrupt this, compromising the integrity of GNSS-derived information. Addressing these challenges requires closer scrutiny of vulnerabilities and the formulation of robust countermeasures to fortify the GNSS infrastructure. This research embarks on exploring adaptive filtering techniques tailored for detecting and eliminating spurious signals introduced by sophisticated spoofing mechanisms. The primary goal is to establish an uninterruptible and dependable GNSS system. The scientific foundation involves a rigorous examination of signal processing methodologies, with a focus on adaptive filtering algorithms adept at discerning original signals from falsifiedones. By delving into these intricacies of adaptive filtering, this research aims to enhance GNSS resilience against spoofing threats, considering the nuanced characteristics of spoofed signals, and developing strategies capable of distinguishing them from authentic GNSS signals. The scientific rigor extends to the formulation of algorithms attuned to dynamic signal variations, ensuring adaptability to evolving spoofing techniques. This scientific inquiry contributes substantively to GNSS security by advancing the theoretical foundations of adaptive filtering mechanisms. Through systematic experimentation and empirical validation, the research aims not only to detect but also to eliminate spoofed signals, fostering an environment where GNSS users can rely on an uninterrupted and resilient navigation system. The results obtained from this study carry the promise of guiding the advancement of advanced counter-spoofing technologies, safeguarding the enduring integrity and reliability of GNSS against continuously evolving adversarial tactics.

Abstract:In this study, a method to broadcast real-time kinematics (RTK) corrections over a communication satellite is proposed. RTK corrections generated by the reference station are uplinked to the communication satellite within a multiplexed DVB-S carrier. Corrections are received by a satellite dish and the DVB-S satellite receiver. Better than 18 cm of accuracy is achieved for rover distances of up to 500 km in Turkey. The proposed method can be used as an alternative satellite-based augmentation system for Turkey and other countries.

“…SOOP beacons can be both land-based stations and space-based transmitters. Examples of land-based beacons include AM/FM radio signal transmission stations [1], [2], terrestrial television broadcast masts [3], [4], cellular communication base stations [5], [6], and WiFi access points [7], [8]. Space-based beacons include commercial planes [9], and various space satellites like low Earth orbit (LEO) satellites, including the Iridium satellites used for communication purposes [10]- [12].…”
