Aerospace Science and Industry has developed a new positioning electronic wristband
The 706 Institute of the Second Academy of Aerospace Science and Industry of China has successfully developed a new positioning electronic wristband product. The electronic wristband product uses CSS linear FM spread spectrum communication technology, AES security encryption technology and TDOA algorithm can realize automatic identification and positioning of personnel. It has the characteristics of low power consumption, high positioning accuracy, strong anti-interference ability, good security and confidentiality, etc. The positioning accuracy reaches 1-3 meters, which is much higher than similar products on the market and is at the leading level in the country and will soon be put into the market.
The national patented anti-tamper wristband technology applied for this product can provide an alarm function as soon as detainees escape, fully meeting the requirements for the supervision of special personnel in prisons and other places. At the same time, it has the extended function of integrating temperature, humidity, vibration and other sensors, and can be widely adapted to the needs of different industries such as justice, mines, and care for special groups.
CASIC’s millimeter-wave cloud-measuring radar occupies the leading position in the domestic market
Twenty-three institutes of the Second Academy of Aerospace Science and Industry of China successfully won the bid for the millimeter-wave cloud-measuring radar of the Institute of Atmospheric Physics, Chinese Academy of Sciences project, this is the first time that the institute has provided products to the Institute of Atmospheric Physics, Chinese Academy of Sciences. Millimeter-wave cloud measuring radar is a new system of weather radar, which represents one of the important development directions of weather radar and has very broad market prospects. In 2006, the 23rd Institute developed the first mobile Doppler dual-polarization millimeter-wave cloud measuring radar in China. So far, only about 8 units have been produced in China, of which the 23rd Institute has produced 4 units, one for the National Meteorological Bureau, Chinese Academy of Sciences services and exports to South Korea, firmly occupying the leading position in the domestic market.
Millimeter wave cloud measuring radar is a new radar application that has emerged with the development of radar technology. In 2006, without any technology to learn from, the 23rd Institute developed China's first mobile Doppler dual-polarization millimeter-wave cloud measuring radar for the National Key Laboratory of Disaster Weather of the China Meteorological Administration Academy of Meteorological Sciences, breaking the It only took one year to complete the delivery and participate in the mesoscale heavy rain field test in South China, which attracted widespread attention from leaders and experts of the relevant domestic meteorological departments and laid a solid foundation for subsequent market development. In 2012, the China Meteorological Administration once again signed a millimeter-wave cloud measuring radar project with the 23rd Institute. In March 2013, the millimeter-wave cloud measuring radar developed by the 23rd Institute entered the international market and won a complete contract from the Korean Meteorological Administration in a bidding process with relevant companies in Germany and the United States. The radar has arrived in South Korea and has been officially put into trial operation at the Boseong-gun weather station of the Korea Meteorological Administration's National Institute of Major Disaster Meteorology (NIMR).
Millimeter wave weather radar is a new system radar developed in recent years. Taking advantage of the short wavelength of millimeter wave, it can detect clouds within an altitude of 15 kilometers above the radar and a range of about 3,000 square kilometers. and fog characteristics. It can analyze the cloud cover, water content in the cloud, water droplet activity trend in the cloud (whether there are rain conditions, providing a decision-making basis for artificial rainfall), whether it contains hail (providing a decision-making basis for artificial hail elimination), and the temperature of the water in the cloud. (When there is sub-zero supercooled water, ice will form on the wings when the aircraft flies through the cloud), fog characteristics (the development trend of the fog, the size and scope of the fog cluster can be judged) and a series of characteristics, It can provide support for atmospheric scientific research, cloud automated observation, artificial weather modification, airport meteorology, military meteorology, etc.
Aerospace Science and Industry has successfully developed a high-temperature resistant silica cable assembly
The 203 Institute of the Second Academy of Aerospace Science and Industry of China has successfully developed a high-temperature resistant silica cable assembly, which can withstand 1000℃ high temperature, product performance has reached the domestic leading level. The successful development of this cable assembly has filled the gap in domestic 1000°C high-temperature resistant cable assemblies. The product performance has reached the domestic leading level, and at the same time, it has achieved certain social and economic benefits. In the future, Institute 203 will serialize this type of products to better meet the needs of users at different levels and better serve the national defense economic construction.
