The reporter learned from the National Defense Science and Technology Bureau on the 14th that the China-Brazil Earth Resources Satellite 04 star was delivered to the China Resources Satellite Application Center by the research unit on the same day and officially put into use. The star can complete coverage of China's land area within 26 days, and obtain image images of 5 meters of full color and 10 meters of spectrum, which can continuously provide stable mid-resolution census data. Has a wide range of application prospects.
After the launch of the star on December 7, 2014, the star successfully completed the test content. The on-orbit test results show that the satellite and ground application systems work stably, and the satellite system is well matched. The satellite, carrier, launch, measurement and control and ground application systems all meet the general requirements for engineering development and meet the on-orbit delivery conditions. As of July 13 this year, the star has processed and produced more than 200,000 scenes of data, playing an important role in the field of crop growth analysis, water body extraction and hydraulic engineering identification, and remote sensing investigation of geological disasters.
The China-Brazil Earth Resources Satellite 04 star was jointly developed by the Space Technology Research Institute of China Aerospace Science and Technology Corporation and the Brazilian Space Technology Research Institute. It is an important embodiment of China-Pakistan cooperation in the space high-tech field and has been praised as a model of South-South cooperation. ".
At the delivery ceremony, Xu Dazhe, director of the National Defense Science and Technology Bureau and director of the National Space Administration, said that in the past 30 years, cooperation between China and Brazil in the field of high-tech space has achieved fruitful results. The Chinese side will take the delivery of 04 stars as an opportunity to actively implement the China-Pakistan space cooperation ten-year plan, strengthen cooperation in the fields of scientific and technological innovation and application, and continue to provide data services to African and Latin American countries free of charge.
Brazil’s ambassador to China, Leon, said that the China-Brazil Earth Resources Satellite 04 star will provide better services to China and Pakistan and the rest of the world for the benefit of mankind. The Pakistani side will continue to work with China to actively promote the development of the 04A star and deepen cooperation in the aerospace field.
In 1988, the two countries signed the "Protocol of the Government of the People's Republic of China and the Federal Government of Brazil on the Approval of the Development of Earth Resources Satellites". In 1999, 2003 and 2007, they successfully launched the China-Pakistan Earth Resources Series Satellite 01 Star, 02 Star and 02B star. On May 19 this year, the two sides signed the China-Brazil Earth Resources Satellite 04A Star Cooperation Protocol, which will push China-Pakistan cooperation in the space field to a new level.
