SSPI How Satellites Make a Better World

The global satellite network is one of the stellar achievements of the 20th Century. And it is a bridge to greater progress in the 21st. From their vantage point high in space, satellites deliver a stunning range of services. Each one depends on the ability to transmit radio frequency signals across vast distances. From Earth to space and back again, distance drains the energy from these signals, requiring all our ingenuity to receive and interpret the information they contain. But interpret it we do. And every day of the year, those tenuous signals inform and educate us, feed the hungry and save lives. They forecast the weather, navigate our vehicles, transact business, restore services disrupted by disaster and fill our free time with entertainment. The list goes on and on. A day without satellite would be a bad day on Earth because of all the essential applications that satellite provide.
