Developed by the University under the FIRST program of Cabinet Office of Japan, the two microsatellites were launched from the Dnepr Launch Vehicle in Russia on 20 June.
Hodoyoshi-3 and 4 are proof-of-concept in innovative satellites each developed a budget of less three million US dollars and development time of less than two years.
Researchers believe that low cost small satellites will enable frequent earth observation using a large number of satellites or the concept of the “personal satellite.”
Hodoyoshi-3 has 40 m and 200 m GSD (ground sample distance) cameras and Hodoyoshi-4 has a 6m GSD camera to capture Earth remote sensing images. Both satellites have “Store & Forward” communication systems to receive various sensor data on ground by RF signal as well as “Rental Space” to accommodate user-specified objects in several 10 cm cubic spaces in each satellite.
