IT Home may 1 news, Beijing time on April 29, 2022 at 12:11:33 a.m., the mainland in Jiuquan Satellite Launch Center with the Long March 2 C carrier rocket using the "one arrow double star" method, successfully sent the "four-dimensional Gaojing No. 1 01 star" and "four-dimensional Gaojing No. 1 02 satellite" into the predetermined orbit, the satellite into orbit after the good state, the telemetry data is normal, each subsystem single machine successively started up.
At 22:00 on April 30, satellite ground receiving stations in Guangzhou and Urumqi successfully received the first images of the four-dimensional Gaojing-1 01 and 02 satellites, respectively. The texture details of the figures in the image are clear, the colors are realistic, and the layers are rich. The space-to-earth link and ground system are operating stably, and the satellite has entered the on-orbit testing phase.
Next, let's enjoy the "meitu" transmitted by the satellite

IT Home learned that compared with the similar optical remote sensing satellites previously launched, the four-dimensional Gaojing-1 01 and 02 satellites have further increased the diameter of the optical lens, and the photosensitive pixels have been replaced by the traditional TDI CCDs with the most advanced CMOS devices, and the signal-to-noise ratio and detail resolution capabilities of satellite images have been further improved, promoting the imaging quality of domestic commercial optical remote sensing satellites to a new height.
Four-dimensional Gaojing-1 01 and 02 satellites are the first satellites of China's four-dimensional new generation of commercial remote sensing satellite system, the system will be fully completed in 2025, the space segment plans to launch a total of 28 satellites "16+4+8", including: 16 0.5-meter resolution optical satellites, 4 0.7-meter resolution wide-format optical satellites, 8 1-meter resolution SAR satellites, synchronous construction of matching "four-dimensional cloud" based ground segment (including measurement and control, reception, processing, application). Subsequently, it can be expanded to 56 satellites according to market developments.
After the completion of China's four-dimensional new generation of commercial remote sensing satellite system, it has a high re-visit capability of 25 times a day in the world, a high collection capacity of more than 30 million square kilometers per day, and an emergency delivery capacity of less than 2 hours.
