Abstract
Over the next decade, self-driving vehicles have the potential to trigger a revolution that will reshape not only the automotive industry but transportation services and infrastructure requirements for cities as well. Multiple constellations of Global Navigation Satellite Systems (GNSSs) will play a critical role in providing absolute Position Velocity and Time (PVT). Next-generation of fully autonomous vehicles will require multi-frequency multi-constellation GNSS receivers to provide sub-decimeter level of PVT accuracy operating in all-time all-weather driving conditions.

This project aims to develop a robust navigation system as part of the Albora’s state-of-art GNSS receiver, which will provide the required navigation accuracy while ensuring safety-critical reliability.
The envisioned navigation unit will incorporate different positioning algorithms such as Real Time Kinematics (RTK), Precise Point Positioning (PPP) and its variants Network-RTK (NRTK) and Fast-PPP. Besides the integration with Inertial Measurement Units (IMUs), the solution would also be able to perform some Extended Receiver Autonomous Integrity Monitoring (ERAIM), with an automatic processing and/or mode switching to use the optimal navigation mode.

The novelty of the approach resides in the integration of a novel correlation hardware (provided by Albora) and a software with a versatile navigation engine (supervised by UPC).

The main challenge of the project is to achieve precise and reliable navigation in urban environments where severe signal blockage and multipath interference is expected.

The outcome of this research project will directly contribute to the Albora GNSS receiver development.
