Start date: 01/09/2022Date of Completion: 28/02/2024Global Navigation Satellite Systems (GNSS) have become the primary marine aid-to-navigation and source of Position, Navigation and Timing (PNT) information. Yet, all GNSS are vulnerable to natural interference, deliberate and accidental jamming and spoofing. Trials have demonstrated that degraded GNSS produce hazardously misleading information and erroneous vessel positions without an alarm being…Prime contractor

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: 02/05/2018To find a presentation summarizing the now completed activity, click here and to find the abstract, click here. The use of Global Navigation Satellite System (GNSS) satellite based navigation is ubiquitous where signals are used for both precision position and timing information. All systems, be they established or emerging, exploit predominantly low power, spread spectrum signals (typically… -
Start date: 09/04/2020Final Presentation Executive Summary Report ERTMS is an EU initiative with the aim of improving safety and increasing interoperability of rail transport through a Europe-wide standard for train control and command systems, replacing existing national systems. ERTMS consists of two parts: the European Train Control System (ETCS), an automatic train protection system providing in-cab train… -
Start date: 05/11/2018The objective of the activity is to study GNSS carrier phase integrity techniques for application in railway safety of life applications, and in particular, the evolution of the European Rail Traffic Management System (ERTMS) with virtual balise detection using GNSS. Carrier phase positioning can achieve a significantly better performance than code-based positioning; however, to date there are no…Subcontractors

Start date: 07/10/2019In the last years, there has been fast progress in satellite on-board computing achieved by the satellite telecommunication industry. On-board processors are more performant, with less mass, volume and power consumption. As regards current and evolving space-based PNT data layer services (e.g. private or public GNSS data augmentations), they usually retransmit data computed on-ground via…Prime contractor

Start date: 04/11/2019Until recently, RTK and PPP technologies have been developed for professional applications, the price not being affordable for mass-market users. Over the last couple of years, however, impressive breakthroughs have been witnessed for mass-market applications. While multi-band GNSS will provide an improved user experience in many consumer settings, the solution alone cannot deliver sufficiently…Subcontractors

Start date: 07/04/2021Current GEO and GTO missions already exploit GNSS signals for in-orbit PNT. NASA’s MMS mission has recently demonstrated that tracking of GPS signals is possible up to 150,000 km from Earth surface (half-way the distance to the Moon). The feasibility of extending the use of GNSS for missions to the Moon has also preliminarily been assessed by ESA via GSP. These preliminary studies have…Subcontractors

Start date: 03/01/2023This project will deliver an MVP of DNA ( Details | Navigation | Addresses ), a smart mapping, addressing and navigation system. The system enables businesses or people to locate pins on maps, and then save them as a unique DNA address. Addresses can be shared by URL and QR code, listed publicly or shared privately, and can also have profiles of information attached to them, as well as list the…
