Spotr: GPS spoofing detection via device fingerprinting
TL;DR: It is asserted that it is possible to create signatures, or fingerprints, of the satellites that allow one to determine nearly instantly whether a received GPS transmission is authentic or not, and that this solution detects all known spoofing attacks, while being fast, cheap, and simpler than previous solutions.

Validation of enhanced orbit determination for GPS satellites with LEO GPS data considering multi ground station networks
TL;DR: This study selects GPS data from three LEOs and 150 terrestrial stations over half-month period to investigate the improved performance for GPS orbits when LEO GPS data are included in the process of POD, and summarizes the orbit accuracy of both GPS and LEO satellites and the improved level of GPS orbits.

Estimation of antenna phase center offsets for BeiDou IGSO and MEO satellites
TL;DR: Based on a global GNSS tracking network, the B1I/B3I ionospheric-free phase center offsets (PCO) are estimated for BeiDou Inclined Geosynchronous Orbit (IGSO) and Medium Earth Orbit (MEO) satellites as mentioned in this paper, where peak-to-peak variations of up to several decimeters or even meters that depend on the solar radiation pressure (SRP) model and the sun elevation angle above the orbital plane (β angle) are found in the daily x-offset estimates.

Single-Epoch, Single-Frequency Multi-GNSS L5 RTK under High-Elevation Masking
TL;DR: This contribution challenges the strength of the multi-GNSS model by analysing its single-frequency (L5), single-epoch (instantaneous) precise positioning capabilities under high-elevation masking and shows that combining L5 signals from GPS/Galileo/QZSS/IRNSS significantly improves both the ambiguity success rates (ASR) and the positioning performance under high elevation mask.
