Boundary conditions for snapshot-based spoofing detection using OSNMA unpredictable symbolsNARA Subscribed
Anti-spoofing techniques for Global Navigation Satellite System (GNSS) receivers are garnering growing interest as crucial facilitators for the deployment of GNSS-based applications and services. To this end, Galileo is providing the Galileo Open Service Navigation Message Authentication (OSNMA), which conveys a set of cryptographic data with the purpose of authenticating the content of the Galileo I/NAV message. Some of these...
Performance assessment of a low-complexity autoregressive Kalman filter for GNSS carrier tracking using real scintillation time seriesNARA Subscribed
Ionospheric scintillation is one of the most challenging sources of errors in global navigation satellite systems (GNSS). It is an effect of space weather that introduces rapid amplitude and phase fluctuations to transionospheric signals and, as a result, it severely degrades the tracking performance of receivers, particularly carrier tracking. It can occur anywhere on the earth during intense solar activity, but the problem a...
