Satellites provide a wide range of communication services, including:

• Telecommunications: This includes telephone calls and services provided to telephone companies, as well as wireless, mobile, and cellular network providers. Telecommunication services are used by governments, the military, and other sectors.

• Broadcasting: Satellites are used for broadcasting services such as satellite TV and radio. They are ideal for "point-to-multipoint" communications, as they can distribute signals from one point to many locations.

• Data Communications: This involves the transfer of data from one point to another. Corporations and organizations that require financial and other information to be exchanged between their various locations use satellites to facilitate the transfer of data through the use of very small-aperture terminal (VSAT) networks. With the growth of the Internet, a significant amount of Internet traffic goes through satellites, making ISPs one of the largest customers for satellite services.

• Remote Sensing & Imaging: Remote sensing satellites detect both visible light for photographs as well as electromagnetic radiation used for microwave, ultraviolet, infrared, radio, and other types of sensing. This information is used by weather forecasters, farmers, natural resources companies, geologists and other scientists, government users, and a host of other customers.

• Mobile Communications: Mobile communications satellites provide ubiquitous voice and data services to users virtually anywhere, far beyond the coverage provided by cellular or terrestrial networks.

• Broadband Connectivity: Many communications satellites provide high-speed broadband services. Many more constellations (networks of satellites) are being launched and developed which will also help bridge the "Digital Divide" and provide connectivity for users on land, sea, and in the air.

• GPS & Navigation: Satellites are used for GPS and navigation services.

• Emergency Response & Disaster: Satellites are used during natural disasters and emergencies when land-based communication services are down. Mobile satellite equipment can be deployed to disaster areas to provide emergency communication services.

In summary, satellites provide telecommunications, broadcasting, data communications, remote sensing and imaging, mobile communications, broadband connectivity, GPS and navigation, and emergency response and disaster services.
