Beijing No. 3 B Satellite has an upgraded version of "Thousand Mile Eyes"

On August 24th, Beijing No. 3 B Satellite was successfully lift off at the Taiyuan Satellite Launch Center and successfully entered. It is equipped with a 0.5 -meter high -resolution Tianshu camera, which is developed by 508 of the Fifth Hospital of the Aerospace Group and will perform the "sky eye" mission at a high altitude of more than 600 kilometers. The satellite provides remote test data services for land and resource management, agricultural resource survey, ecological environment monitoring, and urban comprehensive applications.

Compared with the Tianyu camera equipped with the Beijing No. 3 satellite, the performance of the Tianshu camera is more upper level, and the lens has a larger diameter and brighter. It can identify the goal of 0.5 meters away thousands of miles away, which can be described as "thousands of miles". Wang Jinqiang, the manager of the 508 Tianshu camera project of the Fifth Hospital of Aerospace Science and Technology Group, introduced that the camera uses an optical lens with ultra -long focal length, and the resolution has reached the highest level of domestic business remote sensing. It can be scanned like a scanner, and can also be used as a SLR camera. It can also make video imaging smoothly.

However, if you want to achieve high resolution imaging at high altitude stability, you need to have a strong anti -shake function. The Tianshu camera was equipped with three controlling rods, as if "suspended" on the satellite platform. It effectively isolated the micro vibration of satellite motion components and realized active and stable stabilization under the real -time control system. Using satellite gesture control capabilities, it can also "be eye -catching" to perform high -machine "space live broadcasts" on the target.

The orbit of Beijing No. 3 B has increased by more than 100 kilometers compared to A satellite. Although it is "standing high", it can "see wide and clear". The camera increased the focal length to adapt to higher orbit; broaden the full -color imaging spectrum, absorb more spectral information, is more conducive to color fusion images, and the color details are richer; increase the caliber of the main mirror, the large aperture lens can be capable Further enhance the ability to collect light and improve the resolution; optical system increases the abnormal optical element, further eliminating the final residual distortion.

When the precision aerospace optical lens is installed, the impact of gravity is very critical. Usually the facial effects of dozens of wavelengths caused by gravity will cause the installation to fail. In order to ensure the safety of the "Thousand Miles Eyes", the development team also explored the world's first -class vertical installation technology, so that the installation of high -quality lenses to overcome the impact of ground gravity.

Tianshu Camera also has a smarter "brain". It uses a large number of advanced smart chips, which greatly improves the level of intelligence and autonomy, and uses the same high -performance CPU as the satellite "brain" to achieve the best intelligent imaging of intelligence. Parameters make the shooting easier and have self -correction. The camera can also automatically focus, from the target of dozens of kilometers to the deep space celestial bodies of hundreds of millions of kilometers. The highway of data transmission has continued to broaden, and the speed is more than doubled than the Tianda camera.
