Dongfanghong 5: Let the satellite public platform change from "running" to "lead"

"Dongfanghong, the sun rises ..."

Many people are no stranger to mentioning the "Oriental Red" satellite.

On April 24, 1970, my country's first artificial global satellite "Orient Red One" successfully launched. It not only created a new era of Chinese aerospace, but also sprinkled the heroes of "Space '" "Oriental Red" "and sprinkled it towards it. Universal.

After more than 50 years, China's satellite research and development capabilities have achieved leapfrog development from scratch, from weak to strong, and the "Oriental Red" satellite (platform) family, from "No. 1" to "Fifth" grow--

On December 27, 2019, Wenchang Aerospace launched in Wenchang, China, and the launch of the 20th satellite with the Long March 5 carrier rocket.

On January 5, 2020, the satellite was successfully set at 105.5 east longitude. After a few months, complete all functional verification and new technical tests on the orbit.

At this point, my country has a new generation of large -scale Earth synchronous orbit satellite public platforms with completely independent intellectual property rights- "Oriental Red Five" (hereinafter referred to as the East Five Platform)!

What is the satellite public platform?

"Satellite public platforms are like a bus that achieves the application performance of satellites by carrying different passengers (loads)." Li Feng, a satellite chief designer of the Fifth Hospital of China Aerospace Science and Technology Group, metaphorized.

In this way, as long as a small amount of adaptability is made, different valid loads can be loaded, thereby shortening the satellite development cycle, saving development funds, and improving satellite reliability. According to reports, at present, many countries in the world have adopted the design method of satellite public platforms.

As the first flight test star of the East Fifth Platform, it weighed 8 tons on the 20th and nearly 8 meters high. It carries the longest and longest wing wings in my country. Moreover, in order to meet the multi -load and expansion needs, the 20th has abandoned the traditional bearing cylinder structure and innovatively adopted the truss structure technology to effectively improve the platform's carrying capacity and adaptability.

"If the East Fourth Platform has the strength to compete with the same stage with international peers, then in the East Fifth Platform, we can realize the transformation from running to leading!"

Academician Zhou Zhicheng, the chief engineer of the Fifth Hospital of China Aerospace Science and Technology Group, the 20th Satellite Commander of Practice, and the Chief Commander of the Oriental Red Fifth Satellite Public Platform, said proud that the East Five Platform filled the gap in the Dongfang Red series of large satellite platform spectrum, but can Meet the needs of high -throughput communication satellites in China in the past 20 years.

The ability is super strong, the design concept is new, and the "stunts" of the East Five platform give it a broad application prospect-

It can be widely used in high -orbit communication, microwave remote sensing, optical remote sensing, spatial scientific detection, scientific test, orbit service, etc., which is a rare multi -adaptability platform in the world aerospace field.

"While helping the development of the national economy and bringing more convenience to the people's lives, the East Five Platform can also have greater actions in the fields of technology promotion and commercial aerospace market expansion." China Aerospace Science and Technology Group Fifth Hospital Practice No. 20 Satellite Satellite No. 20 Hao Yanyan, the property insurance manager, said affirmatively. (Guangming Daily)
