Description:

• Hodoyoshi 4 is an experimental earth-observing micro-satellite built by the University of Tokyo. It has a 5 m ground resolution.
• The satellite is built on a 3-axis stabilized earth-pointing bus, which generates up to 100 W electrical power. It features an ion engine propulsion system. The main payload is a high resolution imaging system with a ground resolution of 5 m.
• Additionally it carries a store and forward communications payload and hosted experiments.

Mission details:

• On Jun 19, 2014 launch of a Dnepr rocket from the Yasniy missile base put a record 38 payloads in sun-synchronous orbits ranging from 550 to 610 km at perigee and 620 to 715 km at apogee.
• Hodoyoshi-3 and Hodoyoshi-4 are 60 kg payloads built by AXELSPACE for the University of Tokyo.
  H-3 carries a 40-m resolution camera, a store-forward comm payload and a hydrogen peroxide propulsion system. H-4 carries a 5-m res Earth imaging camera, a comm payload and an ion thruster.
