Laser Communications Site Testing and Analysis

The RSAA Laser Communication Program is a translational research program using cutting edge optics and photonics translated from astronomy for space and communication applications. We use adaptive optics, quantum communication, high power laser systems, single photon detectors, and advanced telescope systems to research the next generation of communication technology. The program has several large funded projects with opportunities for students to get involved and participate in cutting edge and exciting space research. These along with smaller projects are exciting ways for students to be involved in a fast-paced and dedicated research team.

The Laser Communication projects are:

  • A Deep-Space and Lunar Optical Communication System: Optical ground station to support Artemis II

  • Adaptive Optics for Laser Communication: iLaunch Trailblazer

  • Laser Communications Site Testing and Analysis

It is critical that we understand the characteristics of sites in order for a laser communication system to be designed properly. We are interested in the strength of turbulence and prevalence of cloud that will impact the performance of laser communication systems. The laser communications team have deployed a highly sensitive SCIDAR system to the ANU 2.3 m telescope, and have developed a compact and portable RINGSS system for remote measurements.

Activities in this project will include:

  • Analysis of data from the SCIDAR and RINGSS systems

  • Data capture by operating telescope and instrument systems

  • Analysis and simulation of potential optical ground station sites
