China launches marine observation satellite

On October 25, China launched the Haiyang-2B marine satellite using a Long March 4B rocket to observe the oceans.

Haiyang-2B will operate in a 973-km-altitude Sun-synchronous orbit and return real-time marine data including ocean levels, wind speeds and sea surface temperatures across a design lifetime of five years.

The satellite had a mass of around 1,500 kg at launch, and is carrying a range of instruments including a radar altimeter for ocean topography and other measurements, a Doppler orbitography and Radiopositioning Integrated by Satellite (DORIS) for space geodesy and positioning, a laser reflector array, a microwave radiometer and a scatterometer.

In addition Haiyang-2B has global ship identification (AIS) and ocean buoy measurement data collection system (DCS) capabilities.
