Specific features of Grille Curtain LED Display
What is grille curtain LED Display Screen? grille curtain LED Display screen is made up of several pieces single led strip. It is a LED screen which looks like a grille and now become more and more popular among the LED industry. It can be called like strip Led screen. Since it shows us a hollowed-out , meshy visual effect, so LED display experts also call it mesh LED screen. This type of outdoor led screen mainly apply for wall of outdoor, glass wall, top of buildings, Column ads and led Curtain and so on.
Cross-time design of grille curtain LED breaks the limitation of traditional LED display for buildings and walls, makes the assembly project easier and selective. Maybe that is the reason why it can be used widely among all the field. Now let`s CATA editor introduce some technical advantage and how it makes the led screen project easier.

China’s Arrow Samsung successfully launched, the Long March II C carrier rocket is the national casting arrow
On September 29 at 12:21, the Long March II C rocket successfully launched the Remote Sensing Satellite No. 30 01 from the Xichang Satellite Launch Center. The satellite was placed into its designated orbit, marking a complete success for the "One Arrow Samsung" mission. This achievement highlights China's growing capabilities in space technology and multi-satellite launches.
The Remote Sensing Group 30 satellite operates using a multi-star networking mode, designed to conduct electromagnetic environment monitoring and support various technological experiments. This approach allows for more efficient data collection and analysis, enhancing the overall performance of Earth observation systems.
"One Arrow Samsung" refers to a technique where a single rocket launches multiple satellites simultaneously. This method optimizes the use of the rocket’s carrying capacity, reduces costs, and ensures that the satellites remain well-coordinated during their missions. It is a significant advancement in space launch technology, especially for low-orbit and sun-synchronous orbit applications.
Developed by the First Research Institute of China Aerospace Science and Technology Corporation, the Long March II C has been a key player in China’s space program. The Remote Sensing Group 30 01 satellite was developed by the Institute of Microsatellite Innovation of the Chinese Academy of Sciences. This launch marked the 251st mission of the Long March series, showcasing the reliability and experience of China’s space launch system.
Chen Hao, deputy chief designer of the Long March II C, explained that the rocket was upgraded from the earlier Long March II model. Standing at 43 meters tall with a takeoff weight of 245 tons, it has completed 44 successful launches since its debut in 1975. With a success rate exceeding 97%, it remains one of the most reliable rockets in the Long March family.
Chen Wei added that the Long March II C is specifically designed for the medium and low-orbit satellite market, where competition is intense. Its cost-effectiveness makes it an ideal choice for launching small satellites, supporting both domestic and international missions.
The Long March II C, also known as Changji B, is the only rocket in China that has operated from three inland launch sites. Its high reliability has been proven through numerous successful flights. It is also unique in its ability to launch satellites into low-Earth orbit, sun-synchronous orbit, geosynchronous transfer orbit, and large elliptical orbits. In the decade following 1982, it was responsible for all returning satellites in China.
**Historical Review of the Long March II C Launch Vehicle:**
In November 1974, China’s first Changji-C series rocket was developed. By 1985, the Swedish Space Company visited China and signed an agreement to use the Changji C rocket for launching a Swedish postal satellite, marking the beginning of China’s international space cooperation.
In October 1992, the Changji C rocket successfully launched the Swedish Feria satellite, taking a major step toward global recognition. Starting in 1994, it was tasked with launching satellites for Motorola’s global mobile communication system.
By 1997, the Changji C rocket had successfully launched six satellites in succession, placing 12 comets into orbit. This achievement became a model for large-scale commercial collaboration between China and international partners.
In 1999, the improved Changji C rocket launched 7 satellites in a row, earning it the title of “Golden Rocket†from the former Aerospace Industry Corporation.
Since then, the Long March II C has continued to play a vital role in China’s space program, with successful launches from multiple centers, including Xichang, Taiyuan, and Jiuquan. Each mission further solidifies its reputation as a reliable and versatile launch vehicle.
