CSIRO Radio Telescope 3D Laser Scanning

When CSIRO required highly accurate existing-condition information for one of its 22-metre radio telescopes at the Australia Telescope Compact Array near Narrabri, NSW, Scan Hub was engaged to deliver a detailed 3D laser scanning survey.

Using industry-leading 3D laser scanning technology, our team completed approximately 110 individual scans of the telescope, capturing both the external structure and internal equipment rooms. The project included scanning from ground level as well as elevated walkways to ensure complete coverage.

The Challenge

Large engineering structures such as radio telescopes contain complex steelwork, mechanical components and equipment that can be difficult to measure accurately using traditional survey methods. Reliable dimensional information was essential for engineering analysis, maintenance planning and future modifications.

Our Solution

Scan Hub captured the entire structure as a high-resolution point cloud with measurement accuracy of approximately ±1 mm. The resulting digital dataset provides a complete record of the telescope and can be used for precise measurements, engineering analysis, 3D modelling and future documentation without the need for repeated site visits.

Project Outcome

This project demonstrates how 3D laser scanning supports complex engineering projects by delivering accurate existing-condition information that reduces project risk and improves engineering decision-making. Scan Hub provides professional 3D laser scanning, point cloud processing and 3D modelling services for clients across Australia in the infrastructure, research, mining and engineering sectors.
