Position uncertainty during autonomous manoeuvres such as orbit-raising/de-orbiting requires that the local knowledge during low thrust (i.e. with electric propulsion) is accurately determined. Current orbit-raising assumes semi-autonomous control assisted by GNSS, with a long time integral to measure increasing altitude and trajectory of the satellite. The use of a hybrid GNSS unit that…

The use of GNSS observations from reference stations for the derivation of Integrated Water Vapour and assimilated into Numerical Weather Prediction Models has been demonstrated and is in use for weather prediction. With the emergence of multi-constellation and multi-frequency GNSS the possibilities of weather prediction with GNSS are increasing dramatically. Furthermore, with the emergence of…

GNSS antennas in user receiver devices are relatively simple. More sophisticated antennas could be designed to bring spatial diversity and gain, and to be more resistant against spoofing and meaconing, as well as reducing other sources of interference, for instance by nulling the gain of the antenna in this direction. Using arrays of dynamic elements (phase/gain controlled) would also make it…

To find a presentation summarizing the now completed activity, click here. To find the abstract, click here. The DRACONAV project developed an industrial version of a secure GNSS module able to detect GNSS signal spoofing, replay and jamming attacks and provide an estimated PVT (Dead Reckoning) when an attack is detected. The module integrates in a unique casing a multi-constellation GNSS…

Satellites flying in LEO are relying more and more on Precise Orbit Determination (POD) through GNSS and in particular the computation of real time on-board POD with accuracy at centimetre level. Receivers for in-orbit demonstration of Precise Point Positioning (PPP) currently under development under NAVISP (NAVISP-EL1-009: ‘Space GNSS Receiver for Un-Orbit Demonstration of PPP’) and the…

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 communications,…
