On the evening of the 23rd, with the successful launch of the "Hongtu II" 09-12 satellites into orbit and the completion of a series of debugging and transmission of high-definition images and data, the "N ü wa Constellation" composed of 12 commercial radar remote sensing satellites began large-scale applications, providing high-resolution Earth observation images for disaster relief and emergency response, agricultural monitoring, ocean observation, energy development, etc. On November 9th and December 17th, China successfully launched 8 commercial radar remote sensing satellites of the "N ü wa Constellation" into a sun synchronous orbit at a distance of more than 520 kilometers from the ground using the Long March 2D carrier rocket. On the 23rd, it was learned from the Beijing Municipal Science and Technology Commission and Zhongguancun Management Committee that after entering orbit, these 8 satellites have successively completed the deployment of solar panels and data transmission antennas, testing of satellite ground measurement and control data transmission links, satellite status monitoring, and radar remote sensing payload startup in space. They have completed the networking with the four commercial radar remote sensing satellites "Hongtu 1" that were launched into orbit on March 30, 2023 and have already been in orbit. So far, the commercial radar remote sensing satellites of the "N ü wa Constellation" network have reached 12. Clearly visible, it is the first highlight of the "N ü wa Constellation". The 12 commercial radar remote sensing satellites are like 'sky eyes', capable of penetrating clouds, mist, and rain layers, observing the earth around the clock and collecting high-resolution images with an imaging resolution of 1 meter, "said Wang Yuxiang, Chairman of Aerospace Hongtu Information Technology Co., Ltd. Wide coverage is another characteristic of the "N ü wa constellation". The N ü wa constellation plans to launch 114 remote sensing satellites. At present, the 12 commercial radar remote sensing satellites in orbit adopt wheel formation and 90 degree phase formation modes, respectively, and have global coverage capability for ground remote sensing observation. High efficiency is another advantage of the "N ü wa constellation". Our independently developed satellite equipment strives to achieve real-time remote sensing observation capability of 'what you see is what you get' for specific targets, with rapid response and agile observation. It takes less than an hour from sending instructions to the satellite from the ground to transmitting data back to the ground. "Wang Yuxiang introduced that the use of big data processing and artificial intelligence technology has further improved the efficiency of constellation image analysis. So far, the images and data collected by the "N ü wa Constellation" have played a role in the emergency rescue of major natural disasters such as the collapse of the Dongting Lake embankment in Tuanzhou, Huarong County, Hunan Province, supporting event monitoring more than 100 times. By the end of 2025, the 'N ü wa Constellation' will form a network of at least 20 satellites, further enhancing satellite response capabilities and providing faster and more efficient information services Wang Yuxiang said that these high-resolution images and data are expected to have greater applications in emergency disaster reduction, flood prevention and rescue, and natural resource supervision.
