At noon on August 24th, the Beijing No. 3 B Satellite developed by the Fifth Hospital of Aerospace Science and Technology Group took the Long March 2 Ding Yunzai Rockets and successfully launched at the Taiyuan Satellite Launch Center. Subsequently, the satellite entered the predetermined track accurately, and the launch task was successful.

The 0.5 -meter -level high -resolution "Tianshu Camera" developed by the Fifth Hospital of the Aerospace Science and Technology Group is a high -end flagship product in the Beijing No. 3 satellite camera. Provide remote test data services in the fields of urban comprehensive applications, while innovating and expanding emerging markets such as three -dimensional three -dimensional, urban digital bases, and smart agriculture.

"Compared to the" Tianyu Camera "equipped with Beijing No. 3 satellite, the" Tianshu Camera "performance of Bate B is higher." Wang Jinqiang, the "Tianshu Camera" project manager of the 508 House of Aerospace Technology Group, said, The camera uses an ultra -long focal length optical lens, and the camera resolution has reached the current high level of domestic commercial remote sensing.

In terms of forestry management, "Tianshu Camera" can distinguish a single canal, conduct forest fire loss assessment, and monitor illegal logging. In terms of agricultural management, it can achieve accurate evaluation of crop planting area. In terms of urban construction, it can also find illegal buildings and land illegal land.

On the basis of the "Tianyu Camera", the development team of the Fifth Hospital of Aerospace Science and Technology Group has redesigned a stronger optical lens, upgraded and evolved its imaging capabilities; Color fusion images, color details are richer; increased the caliber of the main lens, large aperture lens can further enhance the ability to collect light and improve resolution.

It is worth noting that the optical lens of "Tianshu Camera" uses vertical installation technology. Jiao Wenchun, deputy chief chief of the Fifth Hospital of Aerospace Science and Technology Group, introduced that vertical installation is a tone technology that overcomes the impact of ground gravity. Compared with traditional horizontal installations, it is more suitable for the installation and technology of large -caliber cameras. More challenging.

In order to improve the control performance, "Tianshu Camera" also uses a lot of intimate design, such as the memory calling function kept power -off, which can make the adjustment of various parameters not affected by the shutdown, so that users pay more attention to the need to shoot. Target, more comfortable use.

In addition, compared to the traditional groundwork of the traditional ground, "Tianshu Camera" increases the automatic focus function on the star, so that it can quickly adapt to the shooting needs of different distances. All can be focused.
