Long March 4B | Haiyang 2E
Haiyang 2E (Chinese: “Ocean”), abbreviated HY-2E, is a marine remote sensing satellite of China. The HY-2 series’ primary objective is to measure ocean dynamic and regional environmental trends in the microwave spectral range, plus measurements of parameters such as marine wind vector, marine surface heat and Sea Surface Temperature (SST). These ocean dynamics real-time data aid aero-marine forecasts for the prevention of, and relief in the event of, natural disasters.
Instruments carried include:
* Microwave Radiometer Imager (MWRI)
* Radar Altimeter (RA)
* Ku-band Rotational Fan-beam Scatterometer (SCAT)
The Long March 4B (Chinese: 长征四号乙火箭), also known as the Chang Zheng 4B, CZ-4B and LM-4B is a Chinese orbital carrier rocket. Launched from Launch Complex 1 at the Taiyuan Satellite Launch Center, it is a 3-stage rocket, used mostly to place satellites into low Earth and sun synchronous orbits.
