Hodoyoshi 4 [University of Tokyo]
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.
Hodoyoshi 4 was launched piggy-back with a large number of other small satellites, among them Hodoyoshi 3, on a Dnepr rocket from the Yasni (Dombarovsky) cosmodrome in mid 2014.
