According to CCTV news, at 12:12 on July 27, 2022, Beijing time, the Lijian-1 carrier rocket (ZK-1A) successfully made its maiden flight at my country's Jiuquan Satellite Launch Center.

According to reports, the Lijian-1 carrier rocket also successfully sent 6 satellites for the space new technology test satellite, the orbital atmospheric density detection test satellite, the low-orbit quantum key distribution test satellite, the electromagnetic assembly test double satellite and the Nanyue Science Star. The orbit, the launch mission was a complete success, and the six satellites were used for space exploration, atmospheric density detection and other related technology verification and test applications.

"Li Jian No. 1" is the "Zhongke No. 1 A" (ZK-1A) carrier rocket. It was developed by Beijing Zhongke Aerospace Exploration Technology Co., Ltd. and is currently the solid rocket with the largest carrying capacity in China.

"Li Jian No. 1" also has the advantages of higher carrying efficiency, shorter preparation period, lower launch cost, etc., and will provide a more powerful solid launch vehicle for China's commercial aerospace market.

"Zhongke No. 1 A" has a total length of 31 meters and a maximum diameter of 2.65 meters for the core stage (core one and two cores). The ton-level solid rocket motor has a take-off weight of 135 tons, and its low-Earth orbit (LEO) capacity is about 2 tons, and its 700-kilometer sun synchronous orbit (SSO) capacity is 1.33 tons.

According to the China Securities Journal, recently, Ma Chuanyong, president of Huawei's terminal cloud service payment business group, said in Shenzhen that Hongmeng 3.0 will be released at the end of July.

HarmonyOS 3.0

In mid-June, Huawei's HarmonyOS 3.0 developer beta version opened for public beta recruitment. The new version enhances the JS / eTS language application development capabilities, further improves the ArkUI and ArkCompile functions, and can also develop complex interface applications in JS / eTS language, while improving the application startup speed.

Devices supported by the Huawei HarmonyOS 3.0 developer beta version include the P50 series, the Mate 40 series, and the MatePad Pro 12.6-inch 2021 model.

Earlier this month, the developer beta version of HarmonyOS 3.0 began to be pushed. The update log shows that the HarmonyOS 3.0 Beta version continues the full-scene smart experience, bringing comprehensive improvements in interaction design, multi-device interconnection, performance, and user care.

It is also reported that Huawei will hold a press conference on the 27th of this month to release a variety of new products such as Changxiang 50 Pro, Matebook, and MatePad. Among them, the new smart screen products will be equipped with the Hongmeng 3.0 system for the first time.

At 23:46 on June 27, 2022, Beijing time, the Long March 4C carrier rocket at the Jiuquan Satellite Launch Center to successfully launch the Gaofen 12-03 satellite into the air, the satellite successfully entered the predetermined orbit, and the launch mission was successfully completed. success.

The satellite is mainly used in the fields of land census, urban planning, land rights confirmation, road network design, crop yield estimation and disaster prevention and mitigation.

The satellites and rockets launched this time were all developed by the Eighth Academy of China Aerospace Science and Technology Corporation. The reporter learned from the institute that there are many new states for the first flight of the rocket: in order to adapt to the high-density launch model, the launch site process optimization is applied for the first time, the model is the first to use the fully autonomous alignment technology that can identify the shooting direction, and the first application in the Jiuquan Satellite Launch Center. Digital pressurization control and new research equipment from Wai'an realize the unification of Jiuquan and Taiyuan satellite launch centers.

The fully autonomous alignment technology applied for the first time in the Chang-4 model has been verified by the measured data of multiple launch sites. Compared with the traditional optical aiming to transmit the azimuth angle deviation, the fully autonomous aiming relies on the inertial group measurement data for real-time azimuth calculation and automatic computer binding. The method reduces the risk of personnel transfer, and is not affected by climatic environments such as blowing sand, strong winds, and showers, and improves the versatility and adaptability of the rocket.

The mission is the 425th flight of the Long March series of launch vehicles.

Sina Technology News June 16 noon news, at the Huawei Partner and Developer Conference 2022, Huawei Corporate Vice President and President of the Computing Product Line Deng Taihua was interviewed by the media.

At the meeting, Deng Taihua revealed that the total installed capacity of the entire Euler series has exceeded 1.7 million units, and the new market share has reached 19%.

He said that Huawei will not pursue the increase in the number of Euler partners, but will pay more attention to large-scale deployment. "Be the number one in the new market first, because the replacement of IT is very fast, and then it will take a few years to make enough replacements and upgrades in stock. Not only the increment, but also the stock must be the first."

In his view, these companies can only enter the positive cycle of the industry by allowing the Euler commercial distribution to be deployed on a large scale in the market. Huawei will also use various market sales systems, including those integrated into the entire solution, to help partners open up sales in the market. "We hope that the partners who cooperate with Euler's commercial distribution can achieve commercial success based on Euler. This is our goal."

In addition, at the Huawei Full Connect Conference in 2021, Deng Taihua revealed that Huawei will launch its self-developed programming language Cangjie in 2022 to connect Hongmeng and Euler in the application development ecology.

Regarding the progress of the self-developed programming language Cangjie, Deng Taihua said that Huawei continues to improve its independent innovation in the field of programming languages. Huawei needs to build root technologies, including operating systems, databases, chips, compilers, programming languages, and instruction sets, all of which belong to root.

"The programming language includes the underlying programming language, which is planned to be released in the second half of this year to support diverse computing power. Cangjie is a programming language corresponding to the upper-level application. We are currently in the process of developing programming languages, and we will do it again at a suitable time later. official release," he said.

China's third aircraft carrier

The launching ceremony of China's third aircraft carrier was held on the morning of the 17th at the Jiangnan Shipyard of China State Shipbuilding Corporation. Xu Qiliang, member of the Political Bureau of the CPC Central Committee and vice chairman of the Central Military Commission, attended the ceremony.

At about 11 o'clock, the launching ceremony began, the audience sang the national anthem of the People's Republic of China, and the five-star red flag was slowly raised. Xu Qiliang awarded the naming certificate to the chief officer of the receiving unit, and jointly cut the ribbon for the launch of my country's third aircraft carrier with military and local leaders. Afterwards, a bottle throwing ceremony was performed. The champagne bottle hit the ship's bow and shattered. The ship blew its whistle, the dock door opened, and the aircraft carrier slowly moved out of the dock and docked at the dock. The launching and naming ceremony ended with the singing of the Chinese People's Liberation Army.

Approved by the Central Military Commission, my country's third aircraft carrier was named "Fujian Ship of the Chinese People's Liberation Army Navy", with the hull number "18". Fujian ship is the first catapult-type aircraft carrier designed and built by my country completely. After the ship is launched, mooring tests and sailing tests will be carried out as planned.

Leaders of the navy and China Shipbuilding Corporation Dong Jun, Yuan Huazhi, Lei Fanpei, Yang Jincheng, as well as leaders of relevant military and local departments, cadres and workers of naval research and production units, and representatives of army officers and soldiers attended the ceremony.
