dc.descriptiond tracking based on extracted data from Orolia Simulator that simulates the space environment involving LEO satellites constellation as sensors and UAV as an emitter. Various scenarios modelled using the Orolia Skyde Simulator for quasi-real dynamic trajectories of LEO satellites have been created. Posterior CRLB (PCRLB) has verified the proposed approach to determine the increase in Root Mean Square Error (RMSE) value. The simulation scenarios have been performed using the Monte Carlo iteration. Eventually, the overall achieved results of the proposed approach using data acquired from the Orolia Skyde Simulator were presented and co
dc.description.abstractABSTRACT Satellites, High-Altitude Platforms (HAPs), and terrestrial stations act as relay stations of signals between clients and users of the applications. In addition, satellites applications form a critical part of communication and global navigation systems. Where especially, these applications are used in Civilian and Military fields such as Satellite Communication (SatCom), Digital Video Broadcasting (DVB), high definition video, amateurish radio communications, broadband Internet, weather forecasting, environment surveillance, Global Navigation Satellite Systems (GNSS), Global Positioning System (GPS), remote sensing, as well as geolocation, and target tracking that recognized recently. The rapidly increasing technological development in the space field led to increased satellites and platforms. It increased the entry chance to Outer Space, allowing outlaws to create Jamming and Spoofing Attacks, which are called intentional interference. The increase of satellites may produce crowding in the Radio Frequency (RF) spectrum that produces unintentional interference. Unintentional interference may occur due to spectrum crowded, human error, bad installation, poor equipment, or system design. Consequently, interference management solutions are essential to be overcome Radio Frequency Interference (RFI). Methods to cope with RFI include interference detection, interference mitigation, interference classification, and interference geolocation and tracking.
