Abstract

The world relies on satellite technology for vital communications and entertainment. Over the past 60 plus years, the amount and types of services that satellite networks perform have increased steadily, most often without us realizing it. Systems of manmade objects orbiting above us silently manage basic systems that help us to be safer and more productive. Their entertainment and communication technology control television, telephones, and navigations systems (GPS) used by millions worldwide. In addition, many business and financial transactions between companies and retailers use satellite transmissions to purchase items and services and perform management processes. Further, satellites play a critical role in time-sensitive scientific activities, such as monitoring weather on a global scale and measuring the visual effects of climate and environmental changes, as well as providing valuable information in emergency situations. In developing nations, satellites provide access to education and medical expertise. Not as many people are aware of the increasing dependence of military operations on satellite data for surveillance and secure communications.
