Space Communications, Navigation and Earth Observation Systems in the 5G Era


The 2019 Colloquium entitled "Disruptive Expansion of Space Laser Communications" will be held prior to the ICSSC on Tuesday, October 29, 2019

The Colloquium is organized by the Co-Chairs:

Bernard Edwards, NASA, USA
Zoran Sodnik, ESA, The Netherlands
Morio Toyoshima, NICT, Japan

Colloquium Synopsis

Free Space laser communications, enabling Inter-Satellite Links (ISLs), has recently gathered great attention in the satellite communications industry after many in-orbit verifications. Advanced and cost effective ISLs are being proposed in a number of Low Earth Orbit (LEO) constellations at price points until recently felt to be unachievable. In addition, LEO to GEO optical data relay systems are being planned and deployed in Europe, the United States, and Japan by their respective space agencies and by commercial entities either in partnership with institutions, such as EDRS in Europe, or on a purely commercial basis.
With this progress in optical technologies, Mega-constellations are now being developed by the satellite communications industry, and space laser communication is a key technology to explore new business applications. One remaining development that promises to revolutionize both the remote sensing industry (high speed downlinks) and the GEO/LEO communications industry (two-way feeder links) is a Space to Earth laser connection.
Beyond free space laser systems, the industry is also aggressively seeking ways to introduce optical technologies into the satellite communications payload, both to interconnect and route free space laser ISLs and also to facilitate lower cost and lower mass elements of the payload. Optical techniques are being proposed for applications such as optical beam forming or optical conversion.
The colloquium will explore the current state of the art in all of these optical areas and will project forward to explore the impact of these technologies on future systems and applications.
