Satellite Communication for Security and Defense

Abstract

The contents reported in this chapter reflect the opinions of the authors and do not necessarily reflect the opinions of the respective Agency/Institutions. Today, coalition and national military operations are inconceivable without the support of space-based systems. Space-based assets and applications are essential to navigation; communication; meteorological, geospatial, and imagery services; early warning; and ballistic missile interception. They are a vital enabler for command and control (C2) and situational awareness through the provision of intelligence, surveillance, and reconnaissance (ISR) information. Satellite communications play an indispensable role in security and defense-related governmental communication. They are used when other ground-based means of communication are not possible, reliable, or available. Satellite communications are critical assets in the ability of States to respond autonomously and in a timely manner to global defense, security, and humanitarian and emergency challenges.
