Security & Logistics
There are some 1,000 functioning satellites orbiting the Earth relaying and amplifying information sent through radio frequencies from one point on Earth to another. They form part of the infrastructure that we rely on for safety and quality of life.
Many people do not realise how pervasive satellite services are in contemporary society.
Atomic clocks on the Global Positioning System (GPS) satellites allow the security sector to coordinate security across multiple time zones. Military personnel use navigation satellites and broadband internet can reach rural locations and moving objects such as trains.
Telecommunications satellites provide audio and video connections. Earth observation satellites provide imagery used by the military and governments in early warning weather systems and to monitor the environment.
