Summary

This three-day short course provides accurate background in the fundamentals, applications and approach for cutting-edge satellite networks for use in military and civil government environments. The focus is on commercial SATCOM solutions (GEO and LEO) and government satellite systems (WGS, MUOS and A-EHF), assuring thorough coverage of evolving capabilities. It is appropriate for non-technical professionals, managers and engineers new to the field as well as experienced professionals wishing to update and round out their understanding of current systems and solutions.

How a satellite functions to provide communications links to typical earth stations and user terminals
The various technologies used to meet requirements for bandwidth, service quality and reliability
Basic characteristics of modulation, coding and Internet Protocol processing
How satellite links are used to satisfy requirements of the military for mobility and broadband network services for warfighters
The characteristics of the latest US-owned MILSATCOM systems, including WGS, MUOS, A-EHF, and the approach for using commercial satellites at L, C, X, Ku and Ka bands
Proper application of SATCOM to IP networks

Principles of Modern SATCOM Systems
