The martial arts in the world are only fast and not broken.

Just a month after the launch of the Lynk & Co 05, Lynk & Co announced a new model, the Lynk & Co 06.

Less than three years after the first model was launched in 2017, this is the fifth brand-new model launched by Lynk & Co.

Unlike the industry’s traditional naming method of "the bigger the number, the higher the positioning of the model", the Lynk & Co 06 has the largest number, but it is currently the most entry-level model in the Lynk & Co family. The name of Lynk & Co has always been concise and easy to remember, and the hero is not in order. The Lynk & Co 06 is also a special existence in the Lynk & Co family.

On June 16, at the seven-star Atlantis hotel in Sanya, Lynk & Co 06 completed its world debut through a "deep-sea immersive" press conference. The on-site layout was very futuristic and technological. Just like the positioning of Lynk & Co 06 as "new urban function", the new car had a "mecha warrior" feel from the exterior to the interior.

In addition to the different naming methods, the Lynk & Co 06 also bears many Lynk & Co "first time" labels: this is the first Lynk & Co model built by the BMA-evo architecture, with many breakthroughs and innovations in design.

The team of designers from China and Europe told us that their inspiration came from the diverse architectural forms and digital social life. The original intention of the design was to create a car for the new era of the global urban population, bringing a "luxury from the start" car experience.

The new car is regarded as an advanced work of the Lynk & Co brand’s "urban opposition aesthetics". Although it is an entry-level model of the Lynk & Co brand so far, the Lynk & Co 06 is no less in design and configuration.

From the perspective of the appearance that young people value the most, 06 has the most personalized appearance of the entire family.

Breaking the inertial thinking, from "building a good-looking car" to "making a good-looking car more useful", Lynk & Co 06 has reached a higher level in design: both function and aesthetics, "the mech is in the model, and the function is in it" can be said to be the most appropriate description of its design sense.

Compared with other brothers in the Lynk & Co family, Lynk & Co 06 brings ten innovations in appearance and interior at one time:

New blue and orange contrasting colors, new "Z-shaped" waist line, light body suspended roof, hidden headlight design, two front grille options of "Urban Pulse" and "Digital Building", in addition, the induction welcome light matrix is also unique to Lynk & Co 06. No matter approaching the car from any angle, the welcome light matrix will automatically light up.

This design is in line with Lynk & Co’s consistent tenet and car philosophy: high-end but not cold, using seemingly cold technology to give the driver a warm care.

In the interior part, Lynk 06 adopts a new design officially called "energy fusion cabin", and the central control uses the energy crystal stone to cut the interior board for the first time. The irregular geometric shape carefully arranged is like an energy crystal, and through the advanced INS diaphragm light transmission technology, a highly technological energy crystal breathing ambient light is designed, which echoes the new mechanical dovetail energy crystal tail light. There are 72 color changes, presenting a psychedelic cyberpunk urban style; also adopts a new hand-held electronic file handle and aviation anti-reflection dashboard, which is full of technology.

In addition, the workmanship and materials of the Lynk & Co 06 overall model also maintain the consistently high level of the Lynk & Co brand.

In terms of size, Lynk & Co 06 has a length, width and height of 4340 x 1820 x 1625mm and 2640mm, providing excellent spatial performance. It has designed a lazy back row and up to 37 storage spaces.

Overall, regardless of the design, overall configuration, or manufacturing process, the Lynk & Co 06 is excellent. As the first car built for young consumers, it is a luxury that is accessible and affordable to young people.

After watching the debut press conference of the Lynk & Co 06, the editor girl born in 1994 said that she was a complete fan of the Lynk & Co 06 and was the first car of her life.

According to the official introduction, Lynk & Co 06 will accelerate the pace of listing after its debut, which is expected to be in August this year. After its launch, it will compete in the most mainstream compact market segment and is expected to become Lynk & Co’s most exciting model.

From 01 to 05, Lynk & Co has always given people a sense of individuality. Whether it is the first 01 that focuses on four-wheel drive performance, the high-energy coupe that focuses on trendy personality, or the sports performance, or the extreme sports 05 that has just been listed, every product of the Lynk & Co family gives people a feeling of "not taking the ordinary road".

In terms of sales performance, in May this year, the Lynk & Co brand achieved monthly sales of 12,950 vehicles, an increase of about 27.5% month-on-month and an increase of about 41% year-on-year. In terms of bicycles, the best historical performance is that it has achieved the highest monthly sales of 9,000 vehicles, but after its listing, it replaced the former’s "sales responsibility" position. The highest monthly sales volume exceeded 7,000 vehicles, and the current average monthly sales volume is basically maintained at about 6,000 vehicles.

Up to now, the cumulative sales volume of the Lynk & Co brand has exceeded 300,000 vehicles, which is also the fastest to reach the 300,000 level of China’s high-end.

As a brand new China, Lynk & Co’s current average price of bicycles is 156,000 yuan, and the end point price range is very stable, making it one of the highest premiums in China.

Throughout the history of the industry, new brands continue to emerge, and the competition has become increasingly intense. However, those who can really occupy the C-position on the stage are always those with strong brand power.

Lynk & Co is undoubtedly one of the most successful representatives of Chinese car companies’ brand growth, but based on the entire group’s planning and expectations for Lynk & Co, the burden on Lynk & Co’s shoulders is undoubtedly very difficult. At the beginning of this year, the holding group and group CEO made it clear that Lynk & Co’s future goal is in the order of millions. In the Chinese market, Lynk & Co has to compete head-on with mainstream joint venture car companies.

In order to become a millionaire, there must be more accessible mainstream models in the product matrix, and Lynk & Co 06 is here to shoulder this mission.

From the perspective of the market, regardless of the appearance or interior, Lynk & Co 06 is "very Lynk & Co", but the price and positioning are more affordable, specially designed for young consumers who like Lynk & Co’s design and brand tone, but the budget is not so high.

It has to be said that the move of Lynk & Co 06 has certain risks, opportunities and challenges coexist. Judging from the current exposure of the configuration of Lynk & Co 06, the price of Lynk & Co 06 is likely to be lower than the current average price of the whole Lynk & Co brand bicycle. It is still unknown whether this car will have a certain impact on Lynk & Co’s "high-end China" positioning and the high premium ability after three years of cultivation.

　　Xinhua News Agency, Wuhan, July 12 Question: In 2030, a network of 300 stars will be in operation – decoding the ultra-low orbit and remote integrated satellite constellation

　　Xinhua News Agency reporters Hu Zhe, Tan Yuanbin, Song Chen

　　Low-orbit constellation construction is an important part of national strategic science and technology, and is of great significance for promoting economic development. With the development of society and the improvement of people’s living standards, the demand for satellite communication, navigation, remote sensing and other functions continues to increase. Low-orbit constellation construction can provide more accurate, real-time and efficient services to meet the needs of all parties.

　　On July 12, at the 9th China (International) Commercial Aerospace Summit Forum opened in Wuhan, Hubei Province, China Aerospace Science and Industry Corporation announced the official launch of the ultra-low orbit and remote satellite constellation, and the first satellite is planned to be launched in December. What is the background of the construction of this satellite constellation? What are the main features?

　　Open up a new track for the progress of aerospace science and technology

　　Ultra-low orbit refers to an orbit with an orbit altitude of less than 300 kilometers, which reduces the satellite from the traditional low-Earth orbit to less than 300 kilometers, so that its "remote sensing" to the earth becomes "near-end", so that it has the advantages of low payload cost, small communication delay, and miniaturization of user end points.

　　Li Yanbin, deputy general manager of the general department of space engineering of China Aerospace Science and Industry Corporation, said that by building an open distributed intelligent networked ultra-low orbit space foundation base, by carrying different loads, supplemented by advanced on-board intelligent processing, satellite terminal direct connection, and inter-satellite communication technology, space information can be quickly and accurately obtained, serving the urgent needs of governments, enterprises, and even individuals for higher precision, high timeliness, and high reliability of space decision-making information, which can stimulate the huge potential of the commercial remote sensing market, open up a new track for the progress of aerospace science and technology, and shape the development of the space information industry.

　　Unlike traditional orbits, ultra-low orbit has a complex dynamic environment, with rarefied atmospheric drag and atomic oxygen flux increasing with a nearly logarithmic law as the orbit decreases. To maintain long-term stable and reliable operation of satellites, it is necessary to offset the rapid decay of satellite orbits due to higher atmospheric drag. Although long-term operation in ultra-low orbit requires many technical challenges, the investment value is huge. The United States, Japan and Europe have all launched relevant commercial or scientific sounding activities.

　　See better, faster, understand better

　　The ultra-low orbit and remote integrated satellite constellation aims to develop a large-scale real-time intelligent remote sensing service system in ultra-low orbit, give full play to the natural advantages of proximity, low delay and small road loss, and create an ultra-low orbit and remote integrated satellite constellation and its application system with "small but fine", "fast and smart" and "many and cheap" as differentiated characteristics. It incubates a new domain and new quality space infrastructure for direct connection to user sensing, transmission and calculation, and establishes a new digital economy format for satellite direct connection to mass users.

　　Zhang Nan, the chief designer of the ultra-low orbit remote integrated satellite constellation, introduced that the ultra-low orbit remote integrated satellite constellation mainly has the following characteristics: first, it can see more clearly, and the spatial resolution will reach 0.5 meters; second, it can see faster, and the spatial information will reach the user within 15 minutes; third, it can be seen more clearly. Through intelligent processing on the satellite, direct connection to the star terminal, and inter-satellite communication, the ground centralized processing data link is omitted, and the spatial information can be directly reached to the user end point. At the same time, the cost of a single satellite of the ultra-low orbit remote integrated satellite constellation will be lower, and the optical load weight and cost will be reduced by 50% under the same resolution.

　　Facing the future, the construction of the ultra-low orbit remote integrated satellite constellation will be implemented step by step, including three stages:

　　In the technical and business verification stage, complete the key technology verification of ultra-low orbit satellites, carry out on-orbit technical tests and business verification; in 2024, complete the launch of a 9-star business verification star cluster; in 2025, build a real-time remote sensing business application demonstration system to provide 1-day service response capability.

　　In the stage of large-scale networking, it will be widely used in the industry to form large-scale networking and achieve half-hour response capability. It is planned to complete the operation of 300 satellite networking in 2030, providing a visible light, synthetic aperture radar, hyperspectral, and infrared multi-type OurHours remote sensing service system to form a global 15-minute response capability.

　　In the integrated development stage, complete the comprehensive construction of the business system, achieve instant business response capabilities within 10 minutes worldwide, and provide complete instant perception services.

　　Satellites are becoming more "intelligent"

　　The construction of the ultra-low-orbit remote satellite constellation not only shows our country’s latest strength in the aerospace field, but also breaks through a number of key technologies, providing more opportunities and challenges. According to reports, the satellite will achieve multi-satellite coordination through inter-satellite links, such as the first satellite receives user requests, the second satellite shoots the required information, and the third satellite completes intelligent processing. At the same time, the satellite will also become more "intelligent", capable of real-time processing and intelligent recognition of image data in orbit, and fast distribution of results through inter-satellite links.

　　In the face of the needs of the field of emergency rescue, the ultra-low orbit remote integrated satellite constellation can provide high-efficiency disaster information, which can provide effective data and capability support for emergency rescue, fire monitoring, disaster prevention and mitigation. The satellite application service platform provides users with normalized disaster monitoring and early warning. After an emergency incident occurs, inter-satellite transmission and on-board intelligent processing can efficiently shoot and extract key information, relying on the network to directly transmit to the vehicle or portable end point, within 15 minutes for the first-line disposal unit and front-line command agencies Provide high-efficiency disaster area scene images, efficiently support emergency rescue and auxiliary decision-making.

　　With such a huge constellation construction, how to make a profit is also a topic of concern to everyone. Li Yanbin introduced that on the one hand, commercial profits can be obtained by selling satellites and user end point products (including software), spatial data products and value-added services; on the other hand, by building an ultra-low orbit space base to create a new quality and new domain industrial ecology, and collect payloads for the society to achieve mutual benefit and win-win results.
