The first of five delivered SSJ5 Electrostatic Analyzers (ESA) was successfully launched into orbit onboard the last of the Titan 2 rockets. SSJ5 is integrated into the Defense Meteorological Satellite Program (DMSP) spacecraft (F16) and began its flight at 16:17 on 10/11/03.
The SSJ5 uses a nested spherical deflection plate system to simultaneously analyze electrons and ions over a 90° field of view. It utilizes a space qualified microprocessor that permits customizing data rates, measurement ranges, on board storage, and specific analysis algorithms, such as Auroral boundary detection or real time charging measurements.
