Aerospace science and technology has developed a new positioning electronic wristband.

706 Institute of China Aerospace Science and Technology Seventh Institute successfully developed a new electronic wristband product. This electronic wristband product adopts CSS LFM spread spectrum communication technology, AES security encryption technology and TDOA algorithm, which can realize automatic identification and positioning of personnel. It has the characteristics of low power consumption, high positioning accuracy, strong anti-interference ability, good safety and confidentiality, and the positioning accuracy reaches 1-3 meters, which is much higher than similar products on the market. It is at the leading level in China and will be put into the market soon.

The national patent technology of wristband disassembly prevention applied for by this product can provide an alarm function for detainees to escape immediately, which fully meets the requirements of special supervision in prisons and other places. At the same time, it has the expansion function of integrating temperature, humidity, vibration and other sensors, which can be widely adapted to the needs of different industries such as justice, mining, special population care and so on.

Aerospace science and technology millimeter wave cloud radar occupies a leading position in the domestic market.

Twenty-three institutes of China Second Academy of Aerospace Science and Technology have successfully won the bid for the lasg millimeter wave cloud radar project, which is the first time that the institute has provided products for the Institute of Atmospheric Physics of Chinese Academy of Sciences. Millimeter wave cloud radar is a new meteorological radar system, which represents one of the important development directions of meteorological radar and has a very broad market prospect. In 2006, Institute 23 developed the first mobile Doppler dual-polarization millimeter wave cloud radar in China. Up to now, China has only produced about 8 mobile Doppler dual-polarization millimeter-wave cloud radars, of which 23 have produced 4 mobile Doppler dual-polarization millimeter-wave cloud radars, which serve the National Meteorological Administration and the Chinese Academy of Sciences respectively and are exported to South Korea, firmly occupying the leading position in the domestic market.

Millimeter wave cloud radar is a new radar application with the development of radar technology. In 2006, 23 research institutes developed the first domestic mobile Doppler dual-polarization millimeter wave cloud radar for the State Key Laboratory of Disaster Weather, Institute of Meteorological Science, China Meteorological Bureau, which broke the foreign monopoly. It took only one year to complete the delivery and participate in the field test of mesoscale rainstorm in South China, which attracted extensive attention from leaders and experts of relevant meteorological departments in China and laid a solid foundation for subsequent market development. In 20 12, China Meteorological Bureau signed the millimeter wave cloud radar project with 23 institutes again. On March 20 13, the millimeter wave cloud radar developed by 23 rd entered the international market, and won the all-inclusive contract with the Korean Meteorological Bureau in the bidding with relevant companies in Germany and the United States. The radar has arrived in South Korea and put into trial operation at Baocheng County Meteorological Station of the Institute of Severe Disaster Weather (NIMR) of the Korea Meteorological Administration.

Millimeter-wave weather radar is a new type of radar developed in recent years. Using short-wave millimeter wave, we can detect the cloud and fog characteristics in the height range of 15 km and about 3000 square kilometers above the radar. We can analyze a series of characteristics, such as the size of cloud cover, the water content in the cloud, the movement trend of water droplets in the cloud (whether there are rainfall conditions to provide decision-making basis for artificial rainfall), whether there is hail (providing decision-making basis for artificial hail suppression), the water temperature in the cloud (when supercooled water below zero occurs, the plane will freeze on the wing when flying over the cloud), and the characteristics of fog (the development trend of fog and the size and range of fog mass can be judged).

Aerospace Science and Technology Successfully Developed High Temperature Resistant Silica Cable Assembly

China Institute of Aerospace Science and Technology No.203 has successfully developed a high-temperature resistant silica cable assembly, which can withstand the high temperature of 1000℃, and the product performance has reached the domestic leading level. The successful development of this cable assembly fills the gap of domestic high temperature resistant 1000℃ cable assembly, and the product performance reaches the leading level in China. At the same time, it has achieved certain social and economic benefits. In the future, 203 Institute will serialize such products to better meet the needs of users at different levels and better serve the national defense economic construction.
