In the 1970 s and 1980 s as the new period of reform and opening up approached

the Teng Chong aerial remote sensing experiment

the Tianjin-Bohai Bay environmental remote sensing experiment

and the Ertan hydropower exploitation remote sensing experiment were performed to improve the remote sensing technology cognition of China. These remote sensing experiments were the products of an unprecedented

well-organized technological cooperation among several research bodies. Through these experiments

multidisciplinary in-tegration was implemented and a large number of high-quality professional and technical experts were cultivated. China also achieved many scientific and technological achievements as well as remarkable economic and social benefits. Using remote sensing technology

we improved our capability of recognizing our natural environment

and remote sensing integrated application was successfully introduced into China. Therefore

these experiments were collectively called the "three campaigns" of remote sensing in China. After rapidly developing and accumulating over the last 40 years

spaceborne remote sensing application has entered several important stages and is increasingly becoming a strategic emerging industry oriented through continuous accumulation

bold innovation

and rapid collection. To satisfy the demands of China’s current science

technology

economy

society

and globalization development strategies

the high-resolution Earth observation system

the national civil space infrastructure and long-term development plan

and the global earth observation system（2030） were implemented in China to help the country shift from pursuing foreign advanced technologies to pursuing research and development independently. By paving the way for space remote sensing applications to enter the stages of industrialization and commercialization

these three projects can be collectively called the new "three campaigns" of remote sensing in China. Combined with the Belt and the Road

the implementation of these "three campaigns" will enhance the "going out" strategy

expand the global service ability

and enhance the international competitiveness of China to a new level.
