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, L-SAR 01A was put in space on January 26, 2022, and its first-track data was received in February 9.

The SAR is a microwave-imaging radar system that emits electromagnetic waves to Earth and receives echoes. It can take all-weather, round-the-clock, high-resolution microwave pictures of the land surfaces, monitoring in that way the geological environment, landslides, and earthquakes.

The two satellites are designed to provide high quality data to support land resource, mapping, forestry, and disaster prevention and reduction.
