Weather Monitoring Based on Collaborative Crowdsourcing

The measurement of Integrated Water Vapour using GNSS stations from a network of reference stations have been demonstrated. During the last years, the existence of multi- constellation and multi-frequency GNSS increases the effectiveness and reliability of such measurements for weather prediction. Currently the availability of affordable powerful hand-held GNSS receivers with…

Space GNSS Receiver for In-Orbit Demonstration of PPP

The object of the activity is to design, develop and validate/verified a GNSS space receiver capable to perform on board precise orbit determination (P2OD) in real time using precise GNSS orbit and clock corrections provided either by Geostationary satellites or Galileo Commercial Service (thus allowing on board autonomy w.r.t to ground stations). The concept is similar to what is performed on…

Low-Cost GNSS Antenna Arrays for Improved Performance, Anti-Spoofing, and Meaconing and Interference Mitigation

The activity primarily targets GNSS antennas for autonomous driving vehicles, which is a fast growing market. It is foreseen that future vehicles will rely less and less on humans, and more and more on Advanced Driver Assistance Systems (ADAS), requiring reliable navigation based on several sensors (GNSS and others) in order to ensure security and safety inside and outside the vehicle in all…

Resilient, Trustworthy, Ubiquitous Time Transfer

Secure and reliable time transfer is a key enabler for the next generation of services worldwide. A number of different applications such as 5G mobile broadband, mobile multimedia broadcast, power grids, terrestrial positioning services, financial operations, IoT, big data and cloud processing will require accurate, secure and reliable time information to be able to work consistently and…

High-Altitude Pseudo-Satellites for PNT

High-Altitude Pseudo-Satellites (HAPS) are airships “quasi-”stationed at a height of 20-30 km, in an altitude range where atmospheric winds are milder. HAPS are normally solar powered, unmanned, large, helium filled and semi-rigid; they can be operational for several years.  HAPS have been studied in the telecom domain (ESA GSP HAPPIEST study), where they were briefly considered…

Trusted Radionavigation via Two-Way Ranging

Wireless positioning systems based on passive ranging, as used in GNSS today, are very attractive and represent the most pragmatic and cost-beneficial solution for worldwide positioning in benign, secured environments; however, this may no longer be a one-size-fits-all solution for modern radionavigation usage as the need for complementary solutions offering adaptability, reliability and trust is…

Quantum-based sensing for PNT

The exploitation of quantum physics has already enabled revolutionary technical applications and industries of enormous economic scale. The semiconductor industry alone is currently a €500 billion market, giving rise to industries on an even larger scale (smartphones, computing, software, etc.).  Quantum physics is now again set to radically change several industries, including…
