Power Systems

RFID Astro-Track Tag


External excitation power requirement: -20 dBm



Lunar Link and Interrogator


Power Required  :  Up to 1 kilowatt


For power of this magnitude some large power source will be required to be carried by the astronat.  As the designer does not have a lot of experience with power systems.  This DSP engineer will consult NASA experts on what kind of power systems may be available to the system designer.
