According to the Webster dictionary, it defines a satellite as a man-made object put into orbit around a celestial body, like the earth or the moon. Satellites serve an extensive variety of purposes from transmission of television signals via communication satellites to guidance and tracking systems of defense satellites. For meteorologists, satellites give a comprehensive view of the world’s weather by observing weather and the environment on a scale not possible by other means.

On April 1, 1960, the nation’s first weather satellite, “TIROS I” was launched into orbit, soon after, meteorologists saw the first pictures of a mid latitude cyclone over the northeastern United States. A new age had begun. Since then, weather satellites have been launched into orbit and their capabilities have improved considerably. Today, not only do satellites observe clouds, but measure other non- visible radiation from the earth and atmosphere. This helps us to estimate such aspects as crop and soil conditions as well as monitor concentrations of atmospheric ozone and many other global characteristics.

The purpose of this module is to scrutinize Earth observing satellites and their capabilities in greater detail, focusing on two satellite orbital groups in particular; Geostationary Operational Environmental Satellites (GOES) and Polar Orbiting Environmental Satellites (POES). Finally, this module will show how to interpret visible, infrared and water vapor channel satellite images. Within the SDC factory, talented people generate innovative space-based solutions that link, protect, and transform the world. Satellites designed here are manufactured, tested, and readied for shipment in the Integration and Test Complex (ITC). Encompassing approximately 1 million square feet, this state-of-the-art facility is the largest dedicated satellite factory in the world. Boeing’s satellite experts persist to pioneer technologies and to discover new applications for a wide variety of systems that make a difference in our world today and create possibilities for tomorrow. We are all committed to expanding knowledge of and appreciation for commercial, civil, and military space activities. There are lots of means on how you can study the human earth, just make sure that it is perfectly made. Be very aware of what you are doing. This way, you can assure that you can get the right calculations.
