Track 13,000 Satellites in real-time

"Many people have no idea how many satellites orbit around the Earth. Now you can see the real-time positions of over 13,000 satellites updated every 30 seconds with Google Earth. The satellite positions come from a US government-sponsored database which Analytic Graphics, Inc., has interfaced with to make the data visible in 3D. Zoom around in space and pause to see the names of the satellites. Click on the satellite placemark icons to see more information on each one. Here is a YouTube video showing what the satellite visualization looks like. You can view the actual collection with AGI's KML file  in Google Earth. You can also watch it in your browser using the Earth plugin on this page by Google Earth Blog."

"This KML network link visualizes all earth orbiting objects tracked by the United States Strategic Command (USSTRATCOM) using the satellite database processed by Analytical Graphics, Inc. using the Dynamic Geometry Library. All satellites are tracked in real-time and updated every 30 seconds. 

USSTRATCOM has been tracking space objects since 1957 when the Soviets opened the space age with the launch of Sputnik I. Since then, they have recorded more than 26,000 space objects orbiting Earth. There are currently more than 12,000 man-made orbiting objects, the rest have re-entered Earth's turbulent atmosphere and disintegrated, or survived re-entry and impacted the Earth. The space objects now orbiting Earth range from satellites weighing several tons to pieces of spent rocket bodies weighing under 10 pounds. About 3,000 space objects are operational satellites, the rest are space debris, retired satellites and rocket bodies left over from launches. 

Analytical Graphics, Inc. (AGI) develops commercial off-the-shelf (COTS) analysis software for land, sea, air and space that is relied upon by the national security and space communities. With more than 32,000 worldwide installations, the main applications of AGI technologies focus on battlespace management, geospatial intelligence, space systems and national defense programs. In addition to the STK product suite, AGI produces the desktop software applications Navigation Tool Kit and Orbit Determination Tool Kit; interactive visualization AGI Viewer software; and the embedded technology development tool 4DX.
