STSS Demonstration Satellites Demo Capabilities For Detecting Another Satellite

STSS Demonstration Satellites Demo Capabilities For Detecting Another Satellite: "A Space Tracking and Surveillance System (STSS) Demonstration program satellite showed an increased set of capabilities when it detected and tracked a resident space object - another satellite - on July 19.
The missile defense satellite is one of two STSS spacecraft built by Northrop Grumman Corporation and Raytheon.

The STSS Demonstration program accomplished another first by tracking a National Oceanic and Atmospheric Administration (NOAA) weather satellite for several minutes using multiple track sensor bands, according to Gabe Watson, vice president of missile defense and missile warning programs for Northrop Grumman's Aerospace Systems sector.

Payload sensors on the U.S. Missile Defense Agency's (MDA) STSS satellite look both below the horizon, with Earth in the background behind the tracked target, and above the horizon, with space in the background behind the target.

This allows precision tracking of ballistic missiles through all phases of flight, commonly referred to as "birth-to-death tracking."
