Satellites provide secure and essential communications, navigation, weather, imaging and a host of other services for U.S. customers and others around the world. Governments, media, industry, first responders, and consumers rely on satellite networks to provide primary and backup communications for essential business transactions, operational missions and mass communications. End users in the United States include:
Satellites are the most efficient technology for providing communications coverage to large geographical and sparsely populated areas, including to end-users dispersed throughout entire countries, continents or large oceanic regions. Every day, satellites provide backhaul connectivity for wireless communications and network redundancy to back up global submarine cable communications. In a disaster, satellite-based communications are heavily relied upon by first responders in the first seconds, minutes, hours and days and beyond, when terrestrial communications are disrupted. As these networks are restored, satellites augment local networks, add international connectivity, and allow ongoing media coverage throughout recovery phases from a disaster.
As such, SIA advocates for the following core principles and policies to protect satellite services from interference:
