JIUQUAN, April 7 (Xinhua) -- China launched a new Earth observation satellite from the Jiuquan Satellite Launch Center in northwest China on Thursday.
The satellite, Gaofen-3 03, was launched by a Long March-4C rocket at 7:47 a.m. (Beijing Time) and has entered the planned orbit successfully.
The satellite will be networked with the orbiting Gaofen-3 and Gaofen-3 02 satellites to form a land-sea radar satellite constellation and capture reliable, stable synthetic aperture radar (SAR) images.
These images will boast a 1-meter resolution together with a one-day revisit period, thereby improving the monitoring capabilities of China's land-sea radar satellites.
It will serve the fields of marine disaster prevention and mitigation, dynamic marine environment monitoring, marine research, environmental protection, water conservancy, agriculture and meteorology, while helping to safeguard maritime rights and interests.
The launch marks the 414th mission for the Long March series carrier rockets. ■

The Gaofen 3-03 satellite launched on a Long March 4C rocket at 2347 GMT (7:47 p.m. EDT) on April 6. The liquid-fueled launcher lifted off from the Jiuquan rocket complex in the Gobi Desert at 7:47 a.m. Beijing time.
The Long March 4C deployed the Gaofen 3-03 satellite into an orbit at an altitude of approximately 460 miles (740 kilometers) and an inclination of 98.4 degrees.
Gaofen 3-03 joins two similar Gaofen 3-class satellites launched by China in 2016 and last November.
The civilian-operated Gaofen 3-03 satellite will capture high-resolution all-weather imagery of Earth from its position in orbit. Carrying a C-band synthetic aperture radar, the craft weighs nearly 3 metric tons — about 6,500 pounds — and should help Chinese authorities better respond to natural disasters like earthquakes and floods.
The new satellite will focus on gathering imagery day and night, regardless of weather conditions. The all-weather capability of radar imaging will give officials updated information even if clouds or rain showers block the view of space-based optical cameras.
CASC has previously said the C-band radar instrument on Gaofen 3 satellites can gather information to meet needs in maritime environmental monitoring, emergency response, water conservation, weather observations, and agriculture.
The Gaofen satellites are part of the China High-resolution Earth Observation System, or CHEOS, a network of optical and radar instruments to monitor the environment. China has launched more than 40 satellites under the Gaofen name since 2013.
