The J-MAPS Mission: Improvements to Orientation Infrastructure and Support for Space Situational Awareness

[Abstract] The Joint Milli-Arcsecond Pathfinder Survey (J-MAPS) mission is a star mapping microsat mission proposed for launch in the 2011 timeframe. The primary objectives of J-MAPS are to generate star catalogs that are 15 times more accurate at current epoch (2007) and 100 times denser than those based on the Hipparcos mission, demonstrate the ability to measure pointing to 10 milliarcsecond...

Space Weather Support for Communications

Ionospheric variability (space weather) significantly impacts ground and space-based communications. In essence, the electrically charged particles of the ionosphere (i.e., the partially ionized portion of the atmosphere starting at about 40 nautical miles (nm) above the Earth's surface) can attenuate, totally absorb, reflect, change direction of propagation, and change the phase and amplitude ...

Human Interfaces For Space Situational Awareness

United States defense operations are greatly enhanced by satellites, however these key assets are vulnerable to perils such as space weather or acts of aggression. Unfortunately it is not only difficult to defend against such threats, it can be difficult to determine the cause from the ground. What may at first appear to be a routine system glitch may in fact be something much more serious. Thi...

Wideband Hyperspectral Imaging for Space Situational Awareness

Wideband hyperspectral imaging (WHSI) systems simultaneously collect spectral and spatial imagery across a broad spectrum that includes the visible/near infrared (VNIR), short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR) regimes. These passive optical systems capture reflected sunlight and thermal emissions from targets enabling the characterization of surface m...
