From Satellite Internet to Earth Observation: A Look at Current Satellite Programs

Satellites are an essential part of our modern world. Satellites have become a vital component of modern technology, enabling us to communicate, navigate, and observe the Earth and beyond.

There are many different types of satellites, each with its own unique purpose. They are used for a variety of purposes, including communications, navigation, weather forecasting, and earth observation.

 

Commercial and Government Satellite Programs

Commercial and government satellite programs provide critical services and information to people around the world, ranging from satellite internet and communication services to Earth observation and weather forecasting.

One of the most high-profile commercial satellite programs is SpaceX’s Starlink constellation, which aims to provide high-speed, low-latency internet to users around the world. The company has launched over 1,700 satellites so far and plans to eventually have over 40,000 in orbit. OneWeb is another commercial satellite internet constellation being developed that has launched over 200 satellites and plans to have a total of 648 in orbit.

In addition to satellite internet services, satellite communication companies such as Globalstar and Iridium provide mobile voice and data services through their constellations of satellites. These services are used by a variety of industries, including maritime, aviation, and emergency responders.

Government-run satellite programs also play a critical role in providing essential services and information. GPS, operated by the United States Air Force, provides global positioning services for civilian and military use. The program currently has 31 satellites in orbit. Landsat, run by the United States Geological Survey, provides Earth observation data for scientific and commercial use. The program has launched eight satellites since 1972, which have provided valuable insights into the Earth’s land use and climate.
