Start date: 30/11/2024Duration: 18 MonthsSome of the greatest challenges that connected and automated ground vehicles face are safe path planning, navigation, self-localisation and positioning. This includes the system being able to reason about its environment and decide which path to take or being able to re-plan should the initial path present obstacles or traffic. JLR aims to develop a testbed capable of testing a Factor Graph…Prime contractor

Start date: 28/11/2024Duration: 12 MonthsA concept for precise Time Transfer via Viasat’s Global Xpress (GX) satellites in GEO, ultimately independent of any GNSS, has been developed and referred to as Global Xpress Time Transfer. The concept uses enhanced orbit determination data and will make use of Code Division Multiple Access (CDMA) signals in the global beam of the satellite adjacent to the global signalling channel. In the first…Subcontractors

Start date: 07/11/2024Duration: 18 MonthsFactor graphs are widely used in robotics, especially for simultaneous localization and mapping, but also in filtering and smoothing, model-based signal processing, artificial intelligence, coding and decoding. They serve as probabilistic models where variable nodes are associated with system states, and factors are associated with measurements. The factor graphs techniques have been applied to…Subcontractors

Start date: 09/10/2024Duration: 27 MonthsODYSSEY (Orbits-as-a-Service for Satellite Signals of Opportunity) is funded through Element 2 of the ESA NAVISP programme and is being carried out by GMV-UK. It will develop a precise orbit determination centre for communications satellite constellations. This will be used to provide a new commercial service generating precise orbits for different satellite constellations whose signals can be… -
Start date: 29/09/2024Duration: 18 MonthsThe main purpose of this activity is to evaluate – through simulations and modelling – how the use of quantum sensors can benefit PNT systems. To meet this overall purpose, the following study objectives can be derived: Design and develop sensor models that can provide representative measurements for quantum sensors, Integrate those sensor models within a simulation environment…Subcontractors
