cloud conditions over Earth's oceans. It will collect wind-speed and wind
direction data. The radar works ar 13.4 GHz. It has a 1800 km swath width. Can
measure winds from 3 to 20 meter per second with an accuracy of 2 meters and
direction with an accuracy of 20°
S-band telemetry and command
data downlink in S-band at 2 Mbps; 2 kbps S-band uplink
