What is Satellite Systems

A satellite is defined as any object that orbits any other object. Satellites can be celestial, such as a moon orbiting a planet in the solar system, or a planet in the solar system orbiting the sun. Satellites can also be man-made. Man-made satellites are typically launched into outer space from earth to collect data, photos and other information about Earth and all the many things that exist around it.

History of LANDSAT Program..

The Landsat program was inspired by Apollo moon bound missions.

William Pecora proposed the idea of having remote sensing satellites in space in 1964.

Eight years later, his proposal became reality, and the Landsat program had begun.

Landsat 1 was launched on July 23, 1972. Since then, six other satellites have been launched.

Landsat 7 is the most recent satellite we have launched, providing us the most technological data possible.

LANDSAT 7

Landsat 7, launched on April 15, 1999, is the seventh satellite of the Landsat program. Landsat 7's primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images. The Landsat Program is managed and operated by the USGS, and data from Landsat 7 is collected and distributed by the USGS. The NASA World Wind project allows 3D images from Landsat 7 and other sources to be freely navigated and viewed from any angle. The satellite's companion, Earth Observing-1, trails by one minute and follows the same orbital characteristics. Landsat 7 was built by Lockheed Martin Space Systems Company. Landsat 7 has the capacity to collect and transmit up to 532 images per day. It is in a polar, sun-synchronous orbit, meaning it scans across the entire earth's surface.

Series of LANDSAT launches..

Landsat 5 - launched March 1, 1984

Landsat 6 - launched October 5, 1993

Landsat 7 - launched April 15, 1999, still functioning, but with faulty scan line corrector (May 2003)
