Instituto de Astrofísica de Canarias Advances Telescope Control with PC-Based Automation
The Instituto de Astrofísica de Canarias (IAC), a leading astrophysics research institute based in the Canary Islands, Spain, is enhancing its telescope control systems through the adoption of PC-based automation technology. This move aims to improve the precision and efficiency of large-scale telescope operations, building on a decade-long collaboration with Beckhoff Automation.
Precision Control and Time Synchronization
IAC operates two astronomical observatories and has integrated Beckhoff’s PC-based control and motion control technology into its observation environments. A key requirement is precise position control and accurate time synchronization. The telescope control system utilizes industrial PCs and motion control software, implementing a synchronization function based on a precise time protocol to minimize discrepancies between observed object movement and equipment control. Researchers emphasize the critical role of time synchronization in reliably tracking celestial bodies. Instituto de Astrofísica de Canarias
A Decade of Collaboration
The partnership between IAC and Beckhoff began approximately ten years ago with a joint observation project. This initial project involved a telescope designed to analyze the polarization characteristics of cosmic microwave background radiation and galaxy emission signals within the 10 to 42 GHz frequency range. Beckhoff’s contribution focused on providing key precision control technology for the telescope. Beckhoff Expands Application of PC-based Automation Technology
Expanding Automation Capabilities
IAC is actively working to transform its control systems from individual, separately communicated computers to an integrated structure with remote control functionality. The new system combines open-source upper control software with PC-based automation technology, with verification planned through simulation environments. This advancement extends facility control beyond observation equipment to include lighting and facility management systems. Instituto de Astrofísica de Canarias
Integration with Correction Systems
Automation technology is also being integrated into the observation equipment’s correction systems. During calibration processes using specific wavelength light sources, lighting control and device operation are linked, ensuring connectivity with existing communication infrastructure. The additional correction module incorporates safety control functions tailored to the work environment.
Future Developments
As the demand for precise control and data processing increases in astronomical observation, the implementation of PC-based automation control systems is expected to grow. IAC plans to continue its collaboration with Beckhoff in various areas, including the development of very large telescopes, robotic telescopes and advanced observation equipment.
