ATI's Satellite Laser Communications course
This course will provide an introduction and
overview of laser communication principles and
technologies for unguided, free-space beam
propagation. Special emphasis is placed on
highlighting the differences, as well as similarities
to RF communications and other laser systems, and
design issues and options relevant to future laser
What You Will Learn:
This course will provide you the knowledge and ability to
perform basic satellite laser communication analysis,
identify tradeoffs, interact meaningfully with colleagues,
evaluate systems, and understand the literature.
- How is a laser-communication system superior to
- How link performance is analyzed.
- What are the options for acquisition, tracking and
