The Iridium Satellite Constellation consists of 66 low-earth orbiting, cross linked satellites that provides global satellite voice and data solutions with complete coverage of the earth. Iridium delivers essential communication services to and from remote areas where no other form of communication is available.

This multi-mission air surveillance system can detect, identify and track airborne threats common to combat environments. These include cruise missiles, aircraft and remotely piloted vehicles, as well as rocket, artillery and mortar fire.

Provide advanced imagery and atmospheric measurements of Earth's Western Hemisphere, real-time mapping of lightning activity, and improved monitoring of solar activity and space weather.

The Cross-track Infrared Sounder (CrIS) instrument provides more accurate, detailed atmospheric temperature and moisture observations for weather and climate applications.
