JIUQUAN — China on Sept 21 sent a new ocean-monitoring satellite into orbit from the Jiuquan Satellite Launch Center in Northwest China.

A Long March-4B rocket carrying the Haiyang-2C (HY-2C) satellite took off at 1:40 pm (Beijing Time), according to the launch center.

The HY-2C, the country's third ocean dynamic environment satellite, can provide all-weather and round-the-clock observation of wave height, sea surface height, wind and temperature.

Onboard equipment enables the new satellite to provide information on the identification of vessels, and to receive, store and transmit buoy measurement data in China's offshore and other marine areas.

Developed by the China Aerospace Science and Technology Corporation, the HY-2C will form a network with the previous HY-2B and subsequent HY-2D to carry out high-precision maritime environment monitoring.

The planned satellite network will be capable of carrying out 80 percent of the world's sea surface wind monitoring within six hours, said sources with the China National Space Administration.

Unlike the previous satellites HY-2A and HY-2B — the HY-2C will be placed in an orbit with a 66-degree inclination, which will enhance its capability to revisit wind fields rapidly, according to the administration.

The launch on Sept 21 was the 347th by the Long March rocket series.
