According to Xinhua News Agency, Beijing, January 23, the reporter learned from the 23rd of the Second Academy of China Aerospace Science and Industry Corporation that the airborne millimeter wave mapping radar developed by the institute obtained the first 1 to 5000 scale image in the western mountainous area of ​​Chengdu, making the domestic surveying and mapping market the first. Once I have an image of the airborne millimeter wave mapping radar.
Li Jun, head of the 23 airborne mapping radar team of the Second Academy of Aerospace Science and Technology, said that geographic mapping is a long-term work of the country. Surveying and mapping studies measure the natural shape of the earth's surface and the geometric distribution of artificial facilities. The information obtained can be used for compilation. Maps of various scales for use in urban planning, transportation construction, water development and environmental protection.
There are many cloudy weather in the southwestern region, and the optical mapping equipment is affected by the weather. It is impossible to continue mapping, and many areas cannot update geographic information in real time.
Li Jun said that the 23 airborne millimeter wave mapping radars developed by the company are not affected by the weather, and can work regardless of the weather, rain and snow, small size and strong adaptability, and the millimeter wave radar has short wavelength and high frequency, which makes it It has the characteristics of high measurement accuracy. Domestic multi-type aircraft can be equipped with flights to ensure rapid response and smooth acquisition of images of the measurement area.
It is understood that the surveying and mapping range exceeds 2,000 square kilometers, and 23 radar teams are expected to complete the mission with two flights and initially form mapping data. It is difficult to obtain large-scale and clear geographic information images in southwestern China. The radar developed by 23 is expected to end this problem.
Product categories of Cloth Pen Nib, it is belong to Passive Stylus Pen. Passive stylus pen is characterized by being cheap and without charging. But compared with the active capacitive stylus pen, its tip diameter is larger, so it cannot be used in works with high precision. Using high-quality conductive cloth head, smooth contact with the screen.
