Photonics for Next Generation Satellite Communication Systems

Share

Photonics technologies are an integral part of today’s ground communication networks, carrying massive amount of data across the globe primarily through guided light in fiber optic cables. However, photonics is new and immature for satellite communication applications due to the need for complex Free Space Optics (FSO) systems, the harsh environmental conditions and the relatively small market need. Fortunately, the recent bloom of Low Earth Orbit (LEO) constellation projects as well as key technological developments are paving the way for next generation optical satellite networks, promising unrivaled capacity, latency and geographical coverage. During this talk, M. Lamontagne will introduce those networks and the related optical system architectures. The state of the art of space based optical communications will be addressed as well as the key technological enablers. Among those, the advantages and challenges of optical beamforming as well as optical feeder links will be discussed in further details.

Guillaume Lamontagne

Topic:

Photonics for Next Generation Satellite Communication Systems

Biography:

Guillaume Lamontagne received his bachelor and master degrees in Electrical Engineering from École de technologie supérieure (ÉTS) in 2007 and 2009 respectively. His career in the space industry started fourteen years ago, first as an undergraduate working for the Canadian Space Agency (CSA) and as a postgraduate for the French Space Agency (CNES), before being hired as a communication system engineer at MDA in 2009. Over the last 10 years, Guillaume held multiple positions within the company, transitioning from the design of satellite payload communication systems to the management of large and complex proposals before being appointed Director of Technology for the Payloads line of business. Guillaume’s work focuses on all architectures and technologies required to unlock future satellite communication systems such as large LEO constellations, phased array antennas, optical feeder and inter-satellite links, beam hopping and on-board digital regenerative processors, among others.
