New Concept for Evolutive Mitigation of RFI to GNSS
Radio frequency interference, intentional or not, is considered to be among the main threats to safety-critical and commercial GNSS applications. This includes out-ofband emissions, privacy-protection devices (PPD) also known as in-car jammers, etc. Consequently, many COTS GNSS receivers nowadays integrate mitigation strategies for RF interferences (jamming and spoofing). Moreover, one can note…

An Innovative concept for the Risk Assessment of Geologic Hazards using GNSS and Solid Earth Tides Modelling
It is long debated whether a relation exists between the tidal stress produced by the Moon and the Sun on the Earth crust and the occurrence of difference geologic events, in particular large earthquakes and volcanic eruptions. Clear evidence for this relation has been elusive for a long time. However, the analysis of more complete global earthquake catalogues has shown that a significant…

Multi-layer PNT for SAR
Satellite Search and Rescue (SAR) standards are set and overseen by COSPASSARSAT. SAR instruments are currently flying on board MEO satellites in several GNSS constellations. These platforms complement the existing LEOSAR and GEOSAR satellites. Existing LEO/GEOSAR are slow in detecting an active beacon due to several limitations in design (limited satellites, fast orbits, no independent location…

GNSS Science with Commercial Aircraft
Usage of commercial aircraft and vessels, as platforms for crowdsourcing science and remote sensing, is under study by organisations like the International Hydrographic Organization (IHO) in its Crowdsourced Bathymetry Working Group, or by private companies for imaging and radar applications.
Some advanced passive GNSS-based processing techniques (e.g. exploiting simultaneously direct and…
