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
