Recent Progress of Earth Observation Satellites in China

Abstract

Currently, China has 32 Earth observation satellites in orbit. The satellites can provide various data such as optical, multispectral, infrared, and radar. The spatial resolution of China Earth observation satellites ranges from low to medium to high. The satellites possess the capability to observe across multiple spectral bands, under all weather conditions, and at all times. The data of China Earth observation satellites has been widely used in fields such as natural resource detection, environmental monitoring and protection, disaster prevention and reduction, urban planning and mapping, agricultural and forestry surveys, land survey and geological prospecting, and ocean forecasting, achieving huge social benefits. This article introduces the recent progress of Earth observation satellites in China since 2022, especially the satellite operation, data archiving, data distribution and data coverage.
