Introduction to Space Electronic Warfare (On-Demand Recording)

Recorded on June 25, 2020

This webinar will present the fundamentals of Space Electronic Warfare and its generic application. Electronic Attack, Electronic Warfare Support & Electronic Protection will be discussed. The presentation will discuss the basics of the space environment and how it affects the EW mission area.

To achieve this, the webinar will begin with basic orbitology and show how different orbital regimes affect the EW environment. Next, the webinar will discuss Satellite Communication (SATCOM) fundamentals, uplink focused Electronic Warfare, the doctrinal term Space Control and how Offensive & Defensive Space EW contributes to achieving this.

Space Electronic Warfare is in some ways very similar to terrestrial EW, but in other ways very different. However, for the warfighter, the end result should be a synchronized multi-domain effort utilizing the differences amongst the domains. The end goal of the presentation is understanding the similarities and differences between Space EW and Terrestrial EW.
