As the world’s first forest carbon sink, the successful launch of the active-passive combined observation remote sensing satellite terrestrial ecosystem carbon monitoring satellite marks that’s China – People’s Republic of China’s carbon sink monitoring has entered the era of remote sensing.
The terrestrial ecosystem carbon monitoring satellite was developed by the Fifth Academy of Aerospace Science and Technology Group. It detects the vegetation biomass of terrestrial ecosystems through a combination of active and passive measurement methods, and solves the problems of terrestrial ecosystem carbon monitoring, terrestrial ecology and resource survey and monitoring, and national major ecological projects monitoring and evaluation. It serves the national goal of “carbon peaking and carbon neutrality”, and provides business support and research services for forestry and grassland, ecological environment, surveying and mapping, meteorology, agriculture, and emergency disaster reduction.
The terrestrial ecosystem carbon monitoring satellite is equipped with four kinds of payloads, including multi-beam lidar, multi-angle multi-spectral camera, hyperspectral detector, and multi-angle polarization imager. The comprehensive remote sensing method of spectrum + multi-angle + hyperspectral + polarization” can obtain multi-element remote sensing information of forest carbon sinks, improve the accuracy of carbon sink inversion, and will significantly improve the quantitative level of my country’s land remote sensing.
The Long March 4B carrier rocket for this launch mission was developed by the Eighth Academy of Aerospace Science and Technology Group. It is a normal temperature liquid three-stage carrier rocket. It has the ability to launch various types of satellites with different orbit requirements. The multi-satellite launch, its sun-synchronous orbit carrying capacity can reach 2.5 tons. The rocket of this invention launched two small satellites by means of sidewall loading, namely the Hede-2G satellite and the Minhang Juvenile satellite.

[ Gaofen GF11 full-spectrum spectral imager developed by 508] As one of the main payloads, the full-spectrum spectral imager is a visible-infrared integrated push-broom imaging space remote sensing camera developed by 508. The imager integrates three imaging channels of visible, short and medium wave, and long wave, which can simultaneously obtain remote sensing images in 12 spectrum bands of visible, near-infrared, short wave, medium wave, long wave, and very long wave. The long-wave infrared detector is a key component of the long-wave imaging channel. It is responsible for converting the received optical signal into an electrical signal, and generating the image we see through the signal processing circuit, the satellite data transmission system and the ground system data processing. The photosensitive surface size of the long-wave infrared detector is only 60mm*12mm. It is hard to imagine that there are nearly 20,000 tiny pixels in such a small chip. Through the optimization and improvement of the preparation process of the very long wave detector chip, the sensitivity of the long wave infrared detector has been increased by 3 times, the gray level of the image has been increased by 3.5 times, and the image quality has been significantly improved compared with the predecessors on the Gaofen-5 satellite .
As a typical representative of China’s visible-infrared common optical path push-broom imaging space optical remote sensor, the full-spectrum spectral imager is the load with the widest spectral range among high-resolution multi-spectral remote sensing cameras in China. In addition to the above advantages, it also has Many “artifacts”: it has 3 imaging channels and 12 spectrum bands, which can be imaged day and night; its long-wave infrared spectrum has the highest spatial resolution of 40 meters for international civil satellites; it passes high-sensitivity detectors and high-precision focal planes Temperature control, high-precision radiation calibration and other methods provide support data for quantitative applications of users, and can accurately and quantitatively obtain surface temperature, water surface temperature, temperature difference range, thermal pollution discharge outlet distribution, mineral information distribution, and vegetation coverage from the image.
