The Satellite Catalog Number (SATCAT), also known as NORAD Catalog Number, NORAD ID, USSPACECOM object number, is a sequential nine-digit number assigned by the United States Space Command (USSPACECOM), and previously the North American Aerospace Defense Command (NORAD), in the order of launch or discovery to all artificial objects in the orbits of Earth and those that left Earth's orbit.

The United States Department of Defense (DoD) has maintained a database of satellite states since the launch of the first Sputnik in 1957, known as the Space Object Catalog, or simply the Space Catalog. These satellite states are regularly updated with observations from the Space Surveillance Network, a globally distributed network of ...
The satellite was designated USA-195 under the U.S. military's designation system, and received the International Designator 2007-046A and Satellite Catalog Number 32258. [ 1 ] [ 6 ] References

The RADARSAT Constellation Mission (RCM) is a three-spacecraft fleet of Earth observation satellites operated by the Canadian Space Agency.The RCM's goal is to provide data for climate research and commercial applications including oil exploration, fishing, shipping, etc. [3] With satellites smaller than RADARSAT-2, [4] the RCM will provide new applications—made possible through the ...
A secondary cause for the increase in Satellite Catalog Numbers was the commercialization of space and break-up events and collisions that have created debris objects. [17] Adaptations of the TLE were considered to extend the number of encodable Satellites within the TLE but instead a new format, the CCSDS OMM (Orbit Mean-Elements Message ...
USA-128 was launched at 08:49:00 UTC on 12 September 1996, atop a Delta II launch vehicle, flight number D238, flying in the 7925-9.5 configuration. [4] The launch took place from Launch Complex 17A (LC-17A) at the Cape Canaveral Air Force Station (CCAFS), [5] and placed USA-128 into a transfer orbit.
