Advanced open-loop techniques for high-sensitivity GNSS receivers applied to BOC signals

High-sensitivity GNSS receivers architectures are of interest in harsh propagation conditions in order to be able to keep tracking GNSS signals even at very low C/No conditions (typically down to around 10-20 dBHz, depending on the signal being tracked). For this purpose, open-loop techniques can be used in the estimation of the code delay and the carrier phase and/or frequency, targeting a more robust estimation of those observables. In this process, advanced signal estimation techniques can be applied for the optimum exploitation of e.g. multi-correlation samples.

Artificial Intelligence techniques for GNC design, implementation and verification
The performance of currently available Guidance Navigation and Control (GNC) systems for space is limited by unmodelled effects or uncertain parameters (e.g. sensor/actuator performances and performance degradations). Artificial Intelligence (AI) techniques based on machine learning could be integrated in GNC systems in order to enable on-line learning of the properties of dynamics, environment, sensors and actuators that limit the available performances.

Artificial Intelligence Techniques in On-Board Avionics and Software
There are problems that cannot be solved by traditional algorithmic solutions, especially in the Control domain. They require non-linear adaptive algorithms. Neural Network is one of them.

Multicore implementation of the On-Board Software Reference Architecture with IMA capability.
The works performed by Savoir-Faire, Savoir-IMA and the related industrial activities have not investigated yet the particular impact of a multicore in the hardware topology on the On-Board Software Reference Architecture. The architectural principles are indeed modular enough to minimize the impacts of the use of a new type of processors. Using a multicore (also in the scope of IMA) in this scope is feasible. But specific aspects need to be investigated:

    Magnetic Field Perturbations by Thermo-Electric Effects

    The technical activities covered in this project allowed the creation of several numerical tools that can predict the thermoelectric/thermomagnetic response to different thermal loading conditions, material properties (thermal and electrical) and geometrical configurations.

    Several numerical studies were performed using both commercial and dedicated numerical analysis procedures for the assessment of the thermoelectric behaviour of simple geometries under specific thermal loading conditions.
