SmartSat unveils terminal for faster, safer military communications
SmartSat Cooperative Research Centre (CRC), Australia’s leading space research centre, has unveiled the Compact Hybrid Optical-RF User Segment (CHORUS) prototype terminal to create more stable and secured military satellite communications at the 15th Australian Space Forum. Funded by SmartSat CRC, the world-leading technology embedded in this prototype has been entirely developed in Australia by the Defence Science and Technology Group (DSTG), and industry and academic partners, EOS Space Systems and EM Solutions, Lyrebird Antenna Research, Shoal Group, Australian National University and University of South Australia, following three years of research. Satellite optical communications links offer significantly higher data rates and a lower interception probability than standard civilian and military radio frequency (RF) satellite communications, which are vulnerable to electronic warfare, such as jamming, geo-location and interception. CHORUS aims to address the several limitations of satellite-based optical communications technology and open viable commercialisation pathways for new SATCOM capabilities. The new CHORUS Terminal is a hybrid optical/RF system, integrating an RF antenna and an optical telescope into a system called the AntennaScope™. This ensures users have reliable communications all the time and much higher data rates when optical communication is possible. A recent VIP demonstration day at the Department of Defence Edinburgh base showcased the successful completion of testing and marked the practical conclusion of the two phases of the SmartSat CRC co-funded project. The unveiling of the CHORUS Terminal at the Australian Space Forum is the first opportunity for the space community to see the prototype and discuss its capabilities and potential commercial pathways with members of the R&D project team. The project drew on impressive efforts by DSTG to support testing at their LASER range, including designing and building a ‘pseudo-satellite’ to prove the hybrid RF-Optical aperture worked as designed.
