Towards miniature-satellite-based Quantum Entangled Networks: satellite-to-satellitelaser pointing stability in the presence of LEO aerodynamic torques
Abstract
Significant efforts are being expended globally to develop the technologies required for Quantum Entangled Networks. Such networks offer the promise of distributed secure communications, precision sensing and teleportation capabilities, and will consist of both space-based and ground-based nodes. Australia is an established leader in the development of quantum technologies, and is also rapidly gaining momentum in the development of space engineering, for the purpose of in-orbit space research and in-orbit operations. In particular, UNSW Canberra Space is developing and flying cubesat missions for RAAF, including a pair of 6U spacecraft in formation in Q2 2019. UNSW Canberra Space is also engaged in the development of a joint quantum communications mission with the National University of Singapore known as QKD, which will be the first in-orbit demonstration and investigation of the viability of satellite-to-satellite quantum communications. A significant challenge for the QKD mission, and in turn for space-based Quantum Entangled Networks, is the maintenance of the optical link between satellites, in the presence of perturbations to the spacecraft attitude such as from aerodynamic effects and also from the ADCS pointing knowledge and stability. The project proposed here is a sub-project of the full QKD mission, and will address the challenge of fine-pointing stability and control for the purpose of maintaining laser links between spacecraft over large distances in the presence of such perturbations.
