About

RELIANT4AD develops reliable and high precision positioning for automated driving, leveraging Galileo added-value services and advanced signal-in-space design.

Automated driving

Reliable positioning for a changing road transport sector

Road transport applications, including personal and professional mobility, are going through a true revolution: automated driving. It will change the way people and goods are transported, improve global safety and logistics, and significantly transform complete sectors of the economy in the next decade.

Galileo services

HAS and OSNMA as localisation game changers

The new HAS and OSNMA services from Galileo position Galileo-based receivers as major game changers in tomorrow's automated-driving localisation solutions. These services bring two fundamental characteristics to the localisation solution: high precision and security.

  • High Accuracy Service (HAS), including HAS SL1 and HAS SL2-ready positioning.
  • Open Service Navigation Message Authentication (OSNMA) for spoofing resilience.
  • Multi-frequency, multi-constellation positioning to improve accuracy and availability.
  • Wide-band processing with AltBOC demonstrations.

Project objective

Fostering adoption of Galileo added-value services for highly automated driving

The RELIANT4AD solution aims to foster the adoption of Galileo added-value services and advanced signal-in-space design as a key feature for highly automated driving positioning systems. The Thales Alenia Space-led consortium answers EUSPA needs and objectives through a product-oriented, safety-aware, and market-conscious technical approach.

Galileo and EGNSS differentiators

The project analyses HAS, OSNMA, multi-frequency multi-constellation positioning, and wide-band AltBOC processing as key differentiators for automated-driving localisation.

Integrity design

Safe sensor fusion integrity

The concept combines tightly coupled sensor fusion, multi-layer consistency checks, integrity monitoring, and anti-spoofing resilience to support safe and reliable positioning.

Safety standards

Built around automotive safety-related development frameworks

  • ISO 26262 for road vehicles functional safety.
  • ISO 21448 for safety of the intended functionality.
  • ISO 21434 for road vehicles cybersecurity engineering.

Safety analysis

Iterative safety work aligned with use cases and operating limits

The safety analysis will follow the applicable standards. In particular, the SOTIF approach will enrich the safety analysis through use-case analysis. Trade-offs will be conducted, and the safety process will be followed iteratively with the architecture and operational design domain limitations.

Integrity concept

Sensor fusion designed for safe and reliable positioning

  • Tightly coupled sensor fusion for enhanced continuity and availability in harsh environments.
  • Vision-based collaborative range measurements to strengthen the positioning solution.
  • Multi-layer Fault Detection and Exclusion, majority voting, integrity monitoring, and anti-spoofing resilience.
  • Proprioceptive and exteroceptive sensors, including ASIL B certified radar and lidar-based positioning solutions.
