: marine satellite help China safeguard sea rights cover all waters under the jurisdiction of

[Global Times special correspondent Hangzhou Tian Ren] State Oceanic Administration, National Satellite Oceanic Application Center recently disclosed 2020, China will launch eight marine series satellite, the formation of the jurisdiction of the waters as well as global ocean color environment and dynamic environment remote sensing monitoring of all ability, while strengthening China’s Huangyan Island, the Diaoyu Islands and the Xisha, sand and Nansha Islands all islands monitoring of nearby waters. Marine monitoring from space has become an important way to explore the ocean world.

build three-dimensional monitoring network waters

the 21st century is known as the “Ocean century. This constant motion accounted for 70.8% of the earth’s surface water body in order to conduct a comprehensive and timely understanding to master the law of its activities, probe cleared its the enormous resources, is difficult to rely on the general method. In addition to probe the seabed with a deep dive boat, marine satellite is considered to be a tool for understanding the ocean’s true colors. It can be economic waters of a large area to achieve real-time, synchronous, and continuous monitoring. The use of space technology to monitor ocean, has a very important significance in the maintenance of maritime rights and interests, the protection of the marine environment, the development of marine resources, and mitigate marine disasters.

the development of China’s maritime satellite goal is to set up a complete set of marine satellite system, which includes three series of satellites, ocean color satellite series, mainly in color and temperature of visible light, infrared detection, including the detection elements : chlorophyll, suspended sediment, sea surface temperature, pollutants, contribute to the monitoring of marine fisheries and aquaculture resources and environmental quality status. “Ocean No. 1 series in China belong to the type of satellite. Ocean dynamic environmental satellite series to detect surface wind fields, sea surface height and sea surface temperature, “Marine 2″ series is a kind of satellite. Ocean surveillance monitoring satellite series, mainly used for the monitoring of China’s maritime exclusive economic zone and near-shore marine environment, and thus achieve the maintenance of maritime rights and interests of the above-mentioned areas, disaster prevention and reduction, law enforcement and supervision, improve the rapid response to emergencies capacity. Our future ocean on the 3rd series belongs to the type of satellite.

development of different series of ocean satellites can complement each other, with the series of meteorological satellites, resource satellites, environment and disaster monitoring satellites together constitute our long-term stable operation of the satellite earth observation system, and with the sea monitoring of aircraft, ships, buoys and other observation tools together constitute the protection of the marine environment of the satellite waters dimensional dynamic monitoring network and military and civilian use either system.

promote fisheries production

At present, China has launched three marine satellite, including two “Ocean No. 1″ Series color satellite and an “Ocean” series of ocean dynamic environment satellites, observation monitoring of the marine environment of the South China Sea, including the Huangyan Island. In 2020, China will launch eight marine series of satellites, including 4 satellite ocean color the two ocean dynamic environment satellites and the two ocean monitoring satellite series.

in marine satellite before, our fishermen whose fishing can only be empirically. May 15, 2002, China’s first marine satellite — A Star “of the” Ocean No. 1 took off. The data sent back to the relevant departments to take advantage of its production from March to September, the monthly average sea surface temperature and chlorophyll maps, and marine fisheries production department to provide data in order to increase production alone direct economic benefit is very impressive. According to the monitoring data, the researchers also produced three estuarine areas of the Yellow River, Yangtze River, Pearl River resources survey and vegetation classification map, monitoring our coastal red tide disaster 16 times around the freezing winter months each year on China Bohai The sea ice forecasting period, and to obtain a large number of north and south polar ice sheet data.

April 11, of two marine satellite “Ocean No. 1 B Star launch real-time observation zone area of ??the Bohai Sea, Yellow Sea, East China Sea, South China Sea and the coastal zone. August 17, 2011, China launched an ocean dynamic environment satellites Ocean 2 A Star “, the satellite can achieve full coverage of the monitoring of our waters, including the waters of all the islands near the Huangyan Island, the Diaoyu Islands and the Paracel Islands . Monitoring the the related sea environment, such as whether seaworthy, the suitability of the fishing boat fishing. The satellite measurements wave height can reach international advanced centimeter level, is currently the world’s only in orbit, with all-weather, all-time, large-area, high-precision, global continuous capability to detect marine remote sensing satellite. The future, China will also establish a series of “ocean” ocean monitoring satellite to meet the maintenance needs of monitoring and surveillance of protected waters and islands supervision marine oil spill disaster emergency, maritime rights and interests in adverse sea conditions.

the strongest American power

the

Currently, the world has launched a number of satellites detect marine satellite, in addition to the integrated remote sensing satellite, marine environmental monitoring capacity , about 30 full-time marine satellite. Which American power is the strongest, firing six, three European cooperation in the United States and France 3, three Chinese, two Japanese, two of India. Soviet/Russian launch 12, but the performance in general.

marine satellite development is now experiencing Discover the test, the three stages of the test and applied research. The United States in 1978 launched the “marine satellite ocean dynamic environment satellites, it is the world’s first marine satellite. The strongest overall performance cooperation in the development of the United States and France, to heaven in 2008, “Jason” (pictured), which cost $ 433 million used to draw sea topographic maps, marine weather forecast improvements such as hurricanes, detection The accuracy of 2.5-5 cm, every 10 days to complete the height measurement of the global ocean. Now, Europe and the United States is the construction for the replacement of “Jason 2 Jason the 3rd marine topography satellite. The satellite is expected to launch in 2013. By then, it will achieve the continuity of the high-precision measurements of ocean topography, will build a bridge for the continuous ocean topography measurement tasks. October-December 2012, the French and Indian cooperation in the development of the “Salar” marine satellite launch for precise, continuous measurement of global ocean surface height, to improve the analysis and forecast on global climate change.
