Satellite Laser Communications Training
Satellite Laser Communications Training Course – Hands-on
This Satellite Laser Communications Training 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 communication terminals.
Satellite Laser Communications Training Course – Customize it
- We can adapt this Satellite Laser Communications course to your group’s background and work requirements at little to no added cost.
- If you are familiar with some aspects of this Satellite Laser Communications course, we can omit or shorten their discussion.
- We can adjust the emphasis placed on the various topics or build the Satellite Laser Communications around the mix of technologies of interest to you (including technologies other than those included in this outline).
- If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Satellite Laser Communications course in manner understandable to lay audiences.
