About the Client

The European Southern Observatory (ESO) is one of the world’s leading intergovernmental astronomy organizations, operating some of the most advanced ground-based observatories globally. The Paranal Astronomical Observatory, located in northern Chile, is home to the Very Large Telescope (VLT), one of the most powerful optical telescope systems ever built.

The VLT plays a critical role in advancing our understanding of the universe, requiring engineering systems that operate with extreme levels of precision, continuity, and reliability.

The Challenge

At the core of each VLT unit is the azimuth cable wrap system, responsible for continuously managing the supply of power, data, optical fibres, and cooling systems as the telescope rotates during operation.

This system must meet strict mechanical and operational requirements, ensuring:

  • Continuous rotation without interruption
  • Precise handling of highly sensitive connections
  • Zero tolerance for failure, given the direct impact on scientific observations

ESO required an upgrade to the existing system to improve performance, reliability, and long-term operability, without compromising the integrity of its highly complex and mission-critical infrastructure.

The Solution

Godelius engineered and implemented a comprehensive upgrade of the azimuth cable wrap system on one of the VLT units, focused on enhancing performance while ensuring seamless integration with existing systems.

The solution included:

  • Redesign and upgrade of critical mechanical components, improving durability and stability
  • Precision engineering and alignment, ensuring smooth and continuous operation
  • Integration with existing infrastructure, maintaining full operational compatibility
  • Rigorous validation and testing, aligned with the high standards required for scientific applications

Every component of the system was designed to meet the extreme reliability and precision demands of astronomical observation.

Outcome

The upgraded system delivered measurable improvements in performance and operational reliability, supporting the continuous operation of one of the world’s most advanced telescopes.

Key outcomes included:

  • Enhanced system stability and reliability
  • Increased confidence in long-term operational performance
  • Strengthened collaboration with ESO, leading to additional work on other telescope units

This project demonstrates Godelius’ capability to deliver high-precision engineering solutions in environments where performance is critical and failure is not an option.

From mining operations to world-class scientific infrastructure, we design and implement systems that operate with accuracy, reliability, and purpose.
