Abstract: Satellite communications experience many unique challenges in closing the link budget and providing reliable and resilient data throughput. These challenges range from overcoming the vast distances to managing atmospheric perturbations to generating unique modulations that are both spectrally and power efficient. In this discussion we will briefly cover these various topics including some modulation basics and dive into some of the only communications standards that exist for satellite communications and why they are used to overcome these challenges. This will lead to a brief introduction of some test and measurement solutions that enable these challenging networks to be created and maintained from concept to launch.
