For more than eight years, the DMSP F-15 and RADCAL satellites have been operating past their operational lifetimes and are facing imminent failure, leaving the US military without a reliable means for C-Band radar calibration and performance monitoring. To address the need for a quick, reliable, and low- cost solution, a team of University of Hawaii students has developed a nanosatellite solution to supplement these failing satellites, all with a modest $110K budget and two-year schedule. Our satellite s name is Ho'oponopono, or to make right in the Hawaiian language. While the RADCAL and Ho'oponopono satellites share several common design features, Ho'oponopono exhibits several notable differences from RADCAL in its design as a direct result of advances in technology. While the most apparent difference is Ho'oponopono s 3U CubeSat form factor, which is a fraction of the size of RADCAL s structure, a not-so- apparent difference is the fact that Ho'oponopono is a student-built nanosatellite, fabricated at a modest price. Ho'oponopono was selected by NASA to be a participant in its CubeSat Launch Initiative and is manifested for a 2013 launch.
