Missions of KSAT2


1. Study on Forcast of Localied Downpour and TornadoIn-orbit experiments of an original observation method of atmospheric water vapor.
2. Take Earth Live Images from Space
Ku-band high-speed data transmission, one shot / a few seconds.
3. Basic Experiments for LEO Positioning Satellites
Frequency and phase synchronization between a ground-base system and a satellite.
4. Orbit Determination Experiments with Radio Interferometer
Essential item for nano-satellite orbiting at very low earth orbit.
5. Satellite Tracking Experiment at Very Low Earth Orbi Evaluation of Earth’s atmosphere to the satellite.
6. Verification of Pantograph-type Extending Boom in Space
The boom was originally designed and is fit for compact satellites.
7. Messages of Encouragement from Space to Japan. Hand-lettered messages and heart warming pictures, especially from children responsible for the future.


Dual uplink, Dual downlink and a beacon signal.

Civilian government agencies are expected to procure more satellites for operational missions in Earth observation, meteorology, navigation, and communications. In most countries, communications satellites (comsat) are now primarily acquired by private companies for commercial services, but several governments continue to fund comsat technology development domestically to ensure they have cost-effective systems when needed.
