SPROUT  -SPace Research On Unique Technology-

Abstract

  The SPROUT(SPace Research On Unique Technology)is the third satellite of Nihon University. It consists the satellite main part that has the shape of a cube with sides of 20cm and Inflatable membrane structure of 1.5m total length. SPROUTfs main mission is gDeployment demonstration of the composite membrane surface structureh. That is to say, the SPROUT will deploy this Inflatable membrane structure. In addition to this, the SPROUT will do gtake a photo of the Earthh by using camera and attitude control, gHam radio missionh which means the SPROUT will deliver voice data and image data from the space to ground, and much much more. The SPROUT means gbud (shinme)h, gposterity (shison)h, gyoung person (wakamono)h, gput forth budsh and ggrow rapidlyh in Japanese. We have started development the SPROUT as second satellite project following the SEEDS since 2005 in winter. Get started development, we named the satellite gSPROUTh. We have done a meaning to the name that we inherit the technology which gained by development of the SEEDS, and attempts to acquire and establish the technology of their own, such as lead to the space exploration in the future to leap it.
  At May 24th in 2014, SPROUT was launched by H-‡UA from Tanegashima Space center. And SPROUT is transmitting radio for Earth.

Communication

Communication system of SEEDS are using amateur radio frequency. You can recieve SEEDS's radio wave, if you have enough facilities.
