China has received the first batch of data from its newly launched land observation satellite, scientists in charge of the spacecraft said Tuesday.

The satellite L-SAR 01B was sent into orbit atop a Long March 4C rocket on Feb. 27.

China's L-SAR 01 is a satellite group composed of two satellites equipped with L-band synthetic aperture radar (SAR), namely the L-SAR 01A and the L-SAR 01B. The former was sent into space on Jan 26.

The ground station located in Beijing's Miyun District has tracked and received the downlink data with a total size of 16.55 gigabytes from the L-SAR 01B, said the Aerospace Information Research Institute under the Chinese Academy of Sciences that is responsible for the radar design and data reception of the satellite group.

"SAR" refers to a microwave-imaging radar system that emits electromagnetic waves to Earth and receives echoes. It can take high-definition microwave pictures of the land surface.

The two satellites will be tasked with providing data to support land resource, mapping, forestry, and disaster prevention and relief uses.

China launches new land-observation satellite
Jiuquan (XNA) Mar 01, 2022
China on Sunday morning launched a Long March-4C rocket to place a new land-observation satellite in space. The rocket blasted off at 7:44 a.m. (Beijing Time) from the Jiuquan Satellite Launch Center in northwest China and soon sent the L-SAR 01B satellite into its preset orbit. The satellite will be used to monitor Earth's geological environment, landslides and earthquakes. The mission marked the 408th flight of the Long March carrier rockets, according to the launch center. Chi ... read more
