Start date: 19/05/2021Date of Completion: 21/05/2021Position 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…Prime contractor

Start date: 13/03/2024The objective of the project is to focus on and implement existing time transfer data protocols (NTP, NTS...) and the feasibility of their integration in existing constellations. The scope is to study the overlay of data time transfer protocols (“Data TT”) onto satellite communication protocols. However, the perspective to study 5G NTN frames (“5G TT”) is not left out. The proposed…Prime contractor

Start date: 18/01/2018The 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…Prime contractor

Start date: 15/01/2018GNSS 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…Prime contractor

Start date: 27/07/2018The main objective of the activity is to design and develop a prototype of a GNSS sensor that will support automotive applications. Our strategy is to develop such device in the form of a “software radio” design that can be configured to allow its implementation in COTS system-on-a chip devices. This device is aimed to support multiple GNSS constellation with a multi-frequency… -
Start date: 09/07/2018To 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… -
Start date: 03/09/2018Satellites 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…Subcontractors

Start date: 27/10/2021The demand for accurate, reliable and secure Position, Navigation and Time (PNT) solution, from a number of different applications include the National Critical Infrastructures (CNI), is increasing. GNSS is a key technology for high-performance PNT, due to its high levels of accuracy, global coverage and its lack of service cost. On the other hand, the spoofing of GNSS is an evolving threat,…Prime contractor

Start date: 10/11/2022The objective of LOCFIT (LOCalisation For Iot and Tracking) project is to develop innovative and robust infrastructure-based position-bounding solutions that exploit satellite uplink measurements of connected devices. Targeted users are low energy and low cost devices, with long life duration without maintenance, dedicated to : Land transportation: tracking of critical…Prime contractor

Start date: 28/03/2023MEOSAR is the new reference for Cospas-Sarsat system, relying on SAR payloads deployed on all GNSS constellations and MEOLUTs deployed worldwide. The first two MEOLUTs (Florida, France) have been officially approved in 2016. However, first operational results have rapidly shown a performance degradation compared to LEOSAR when the beacon was moving. Since then, it evolved to take into account…Prime contractor
