HODOYOSHI-4

About

Hodoyoshi-4 is a Japanese micro-satellite launched in 2014. The satellite is built in 0.5x0.6x0.7m box-shape bus, optimized for piggy-back launch. All instruments are powered by solar cells mounted on the spacecraft body and two stub wings, with estimated electrical power of 50W. For orbit-keeping, a "miniature" ion thruster with specific impulse of 1100 s and operating power of 20 W is integrated into the body. The satellite was developed under the Funding Program for World-Leading Innovation R&D on Science and Technology.
