Foreign Ministry spokesman Wang Wenbin said at a regular press conference on August 31 that China will hold the third the Belt and Road Forum for International Cooperation in Beijing in October this year. This is not only the most grand event to commemorate the 10th anniversary of the "the Belt and Road" initiative, but also an important platform for all parties to discuss and jointly build high-quality "the Belt and Road" cooperation.

Wang Wenbin said that the "the Belt and Road" initiative, with connectivity as the main line, aims to provide a new platform for international economic cooperation and new impetus for the development of countries and world economic growth. In the past 10 years, the "the Belt and Road" has become a popular global public product and international cooperation platform.

Recently, the enterprise of Beidou Xingtong and Xinxingtong recently released a new generation of ultra-small full-system multi-frequency and high-precision RTK positioning module UM960, which provides high-fixed rate, high-precision and reliable GNSS positioning data for intelligent robots, deformation monitoring, unmanned aerial vehicles, handheld GIS and other fields.

UM960

The size of the UM960 is 12mm16mm2.6mm, which can bring greater freedom and flexibility to the customer's hardware design. While reducing the difficulty of integration, it can make the terminal product design more integrated and smaller in size, so as to expand to more application scenarios.

Compared with the previous generation of star products, the UM960 cloth plate area has decreased by 84%, and the smaller cloth plate area can also bring cost savings to customers.

The UM960 independently developed by Hexinxingtong supports Beidou, GPS, Galileo, GLONASS and QZSS navigation systems, and the frequency points support BDS B1I/B2I/B3I/B1c/B2a *, GPS L1/L2/L5, Galileo E1/E5b/E5a, GLONASS G1/G2, QZSS L1/L2/L5. The support of multi-frequency points in the whole system enables the UM960 to obtain more available satellites and observations under the same occlusion conditions, improve its data availability under severe occlusion scenarios, improve the fixed rate, and meet the application requirements of various scenarios in different regions.

 UM960 支持北斗

Thanks to the powerful chip performance of Nabulas IV, the overall performance of UM960 has been significantly improved. The UM960 floating-point computing power has been increased by 5 times, the module computing power has been greatly improved, and the RTK solution time has been greatly shortened; In terms of data output, it supports single point positioning+RTK positioning data 20HZ stable output. In addition, UM960 supports 1408 channels to meet the expansion needs of current and future frequency points.

The UM960 ensures that the power consumption is less than 450mW in the case of small size, which is 75% lower than the previous generation of products, and can better meet the industrial application requirements with strict power consumption requirements. The low power consumption feature of UM960 is conducive to solving the problem of working hours of handheld portable devices and other industrial products. In deformation monitoring and other industries, low power consumption can help customers reduce costs.

UM960 supports independent tracking and acquisition of each frequency point. When a certain frequency point is interfered, other frequency points still work normally to ensure that UM960 module can still locate normally in the interference environment.

The UM960 interference detection function can visually display the intensity of interference signals in the current environment. In the performance UAV industry, the environment can be detected before the flight performance to effectively prevent the occurrence of flight accidents; When mapping the location of CORS stations, it is necessary to confirm whether the environment is clean. The UM960 interference detection function can easily detect whether there is interference in the environment, effectively shorten the initial location time of CORS stations, and save the cost of site selection and station construction.

Based on its excellent performance, UM960 can also solve the application pain point problem of low fixed rate and poor accuracy in severe occlusion scenarios, and provide accurate and reliable positioning data for terminal products.

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.
