Abstract
Secure optical communications networks are a functional requirement for many military, government, and civilian applications. Optical free space links provide security due to the small ground footprint of highly collimated laser beam patterns. Space-based optical communications provide an additional layer of security due to dynamic angular tracking requirements and remote orbiting infrastructure. The addition of Quantum Key Distribution (QKD) adds a third layer of safety through the use of physically unbreakable keys. The QEYSSat mission is scheduled to launch in 2022. This mission will carry a primary QKD science payload and a secondary high-speed optical communications demonstration payload. The QEYSSat secondary communications payload (QP2) is the latest space-based optical communications terminal designed to be amenable to low cost mass production methods, meeting the price targets of many planned low-earth-orbit optical communications constellations. The successful demonstration of both technologies on a single micro-satellite platform demonstrates the key technologies necessary to enable next generation high speed secure communications networks. In this paper we present an overview of the QEYSSAT optical payloads and describe secure architectures for QKD-enabled optical communications network applications.
