China Receives Data from Atmospheric Environmental Monitoring Satellite

China Remote Sensing Satellite Ground Station (RSGS), a major national S&T infrastructure hosted by the Aerospace Information Research Institute (AIR) under the Chinese Academy of Sciences (CAS), confirmed on April 21 that it received data from the newly launched atmospheric environmental monitoring satellite.

At 11:46 a.m. that day, the Miyun Station at the outskirts of Beijing successfully tracked and received the first-track downlink data from the satellite. Then, the Sanya Station in southern China conducted data reception at 1: 17 p.m. and 2:55 p.m. 

A total of about 133 GB of satellite data was well received and processed, and the total data duration of the three receiving tasks is 24 minutes and 24 seconds.

The science satellite, also known as DQ-1, is the world’s first satellite using LiDAR (light detection and ranging) technology to detect carbon dioxide, or CO₂. 

Launched on April 16 as part of China’s civil space infrastructure, DQ-1 will track fine particles, pollutants, greenhouse gases, clouds, and aerosols in the atmosphere, plus land surfaces and water bodies.
