TIMED Technology Advances
Volume 24, Number 2 (April–June 2003)

TIMED spacecraft in orbit after launch aboard a Delta-II rocket. TIMED technology advances include increased autonomy, onboard orbit determination, event-based commanding, integrated electronics modules, a GPS navigation system, and a peak power tracker. These innovations enabled TIMED's four instruments to operate around the clock at their full capacity, thus lowering mission operations costs while enhancing science return.
