P1.18 Coherent Free-Space Optical Communications (Phase 2)

Advanced Communication, Connectivity & IoT Technologies

Sascha Schediwy, The University of Western Australia

In Phase 2 of SmartSat CRC Research Project 1-01, we propose to further develop an advanced optical communications system that has been shown to support optical fibre-like data transfer rates over atmospheric free-space communication links. This communication system is based on active optics-assisted, coherently phase-stabilised, optical communication technology; the efficacy of which is currently being investigated over horizontal free-space links. Phase 2 of this research project will focus on deploying this technology on a series of vertical links through Earth’s turbulent atmosphere, starting with low-altitude targets, progressing to light aircraft and stratospheric vehicles.
