Satellite Programme: Advanced Land Observing Satellite
Programme details
Programme description
Original name: “Daichi” = "Great Earth".
Series of 3 satellites for land observation.
Japanese programme: JAXA responsible of development and operations.
The platforms are actively stabilised over 3 axes.
The design life time is 5 years.
The satellites exploit sunsynchronous orbits around 10:30 or 12:00, depending on the specific payload.
The replacement policy is based on launching satellites in sequence, roughly 6 months before the expected end-of-life of a satellite.

.
Data circulation
Primary data transmission mode: real-time through DRTS (Data Relay and Test Satellite) to the Hatoyama ground station.
Real-time transmission of selected data in X-band to Hatoyama.
The JAXA Earth Observation Center (EOC) coordinates processing, analysis and distribution through a network of several ALOS Data Nodes (ADN), ideally one in each continent.
