HSU-SAT 1 [HSU]

HSU-SAT 1 (Happy Science University Satellite 1) is a educational CubeSat (1U) built by the Happy Science University in Chosei, Chiba, an organization of the Happy Science cult.

The objectives of the satellite are:

• A technology demonstration of Electrical Power Supply On Board Computer and other bus components.
• HSU-SAT1 performs three-axis attitude control by combining aerodynamic stabilization and magnetic torquers.
• The modulated infrared light emitted from our ground station is experimented as command transmission link. The command format conforms to the infrared remote-control system used in electrical appliances.
• Camera image is downlinked by Slow Scan Television. The camera takes a photograph of the Earth with a resolution of is 320×240 pixels. The photograph taken is converted into analog SSTV signal, transferred to Communication and sent by FM-SSTV downlink.
• A technology demonstration of gyro sensor and magnetic sensor which has not been confirmed its operation in space.

The satellite launched on board of Dragon CRS-25 on a Falcon-9 v1.2 (Block 5) rocket to be delivered to the ISS, from where it is to be deployed via the JEM airlock.
