Observing Systems Capability Analysis and Review Tool
Satellite Programme: Cyclone Global Navigation Satellite System
Constellation of 8 satellite equipped with GPS receivers for the direct signal from GPS and the signal reflected by the sea surface. The spread of the two signals is related to the sea-surface wind speed.
USA programme: NASA responsible of development and operations.
The platforms are 3-axis stabilised.
The design lifetime of the satellites is 5 years (2 years + extensions).
The satellites exploit a low-inclination orbit (all 8 satellites in the same plane).
