At present, the global aerospace industry is in a golden period of rapid development.

China's commercial aerospace industry has also been actively encouraged by the state in recent years, and policy support has become a strong driving force for the development of the aerospace industry. Among them, rocket launching and satellite manufacturing have entered the practical stage, while the development of commercial remote sensing market is still in its infancy, with broad prospects and huge growth potential. With the rapid development of application scenarios, the market has a high expectation of data application, and the demand is increasing day by day. As a participant of the track, Ms. Xi Xiaofei, founder and CEO of Sixiang technology, said: "in recent years, the government has encouraged private enterprises to participate in the aerospace industry, given strong support to the development of the industry, and made a large number of new and cutting-edge forces develop rapidly. In this environment, with the industry-leading technical advantages and the support from capital, four image technology has achieved rapid growth in the past two years. " Ms. Xi Xiaofei, founder and CEO of Sixiang technology, was interviewed by the media at the hi tech fair to explore the new direction of the industry's track with the heart of the universe With years of solid technology accumulation, we have been committed to establishing the application channel between remote sensing satellite data and actual people's livelihood, so that it can be applied to more application scenarios.

In China's commercial aerospace industry chain, four image technology is the closest to the terminal application and the largest value-added potential. Through algorithms and technologies such as image big data analysis, it can intelligently mine and extract depth information from massive remote sensing data information, and finally realize the cross application of remote sensing information and real economy industries. The SAR satellite to be launched is an important step for the four image technology in the new direction of industry. At present, Sixiang technology has obtained a number of industry qualification certification, and has 8 national invention patents and 18 software copyrights. The company has the top-level professional configuration of overall, test and operation control, operation, ground processing and application analysis, master the multi-source and multi load remote sensing data ground processing system, remote sensing information deep mining, artificial intelligence information extraction, standardized data services and other core technologies, and can provide industrial information consultation, twin scene construction, financial information mining, insurance underwriting evaluation, navigation Accurate update, environmental protection red line supervision, ecological quality assessment and other diversified product services. The business scope covers infrastructure operation and maintenance monitoring, twin smart systems represented by digital smart factories and smart ports, space information and driverless support, and commercial and financial data applications. It can be said that Sixiang technology is not only a satellite data application company, but also a cooperation channel and platform between Aerospace ecosystem and other industries.

How can remote sensing technology be applied to all kinds of scenes? Four image technology gives the answer in the process of continuous exploration and attempt. In 2018, Sixiang technology took Mianyang City, Sichuan Province as a pilot to help the State Grid carry out the safety monitoring of UHV transmission network channels, the most important task of which is to measure the height of the trees attached to the grid to eliminate the hidden dangers of trees. The traditional power grid security maintenance is usually in the form of manual regular patrol. The patrol frequency is only half a year, which is low efficiency and high cost. With the help of remote sensing technology, the four image technology can achieve weekly monitoring frequency, accurate image to each tree, and accurate growth height to cm. In addition, satellite remote sensing technology can also be used as an important basis for whether trees are planted intentionally or not. Power grid companies can negotiate with local farmers on this basis, greatly reducing the amount of compensation for felling, greatly reducing the maintenance cost, thus saving the national funds. In addition to the field of infrastructure operation and maintenance monitoring represented by power grid security monitoring, the application of remote sensing technology of four image technology has also made remarkable achievements in the field of agricultural insurance. In Chongzhou City, Sichuan Province, Sixiang Technology launched a data support pilot project for agricultural insurance.

Through the satellite remote sensing monitoring of the distribution range and planting area of rice planting fields in the city, the precise confirmation and detailed classification of rice field boundary are realized, so that the online access map can be accurate to rice, and the rice yield estimation model is established based on the expert knowledge base Finally, the production forecast report is generated. It is worth mentioning that in order to ensure the accuracy of the data to the greatest extent, the chief expert of Sixiang technology led the whole team to harvest rice in the farmland in person and weigh it after drying, threshing and other processing. This rigorous and practical work attitude has finally yielded surprising results - helping the insurance company to accurately eliminate the false report and increase report of more than 1000 mu of planting area in the underwriting stage, and the underwriting efficiency has been improved by more than four times, and the error between the final output estimation result and the actual harvest of each field is within ± 5%. "At this stage, China's commercial aerospace industry chain is not perfect, and the development of commercial remote sensing still faces certain challenges and difficulties. Most enterprises do not have their own data sources and do not have an advantage in the field of information analysis with high data costs," said Xi Xiaofei, who adheres to the original intention and industry mission to make data applications benefit the people. For this reason, the choice of Sixiang technology is driven by the needs of users, which forces the development of industrial ecology. " Talking about the future development prospect of four image technology, she is confident: "in the future, while strengthening the existing product advantages, we will actively expand the integration and innovation in other business areas, and explore new service development direction to adapt to the changing market demand. As an enterprise aiming at serving the people's livelihood, Sixiang technology is committed to making remote sensing data really reach ordinary users and become a right-hand assistant in our daily work and life like mobile navigation. "

In recent years, with the strong pursuit of capital, commercial aerospace industry is booming, new companies are springing up, and star making plans emerge in endlessly, dazzling people. However, Xi Xiaofei and her team always firmly believe that the aerospace industry is an industry that needs perseverance and persistence, step by step, step by step; in the process of development, we should always adhere to the original intention of the aerospace people, never forget the industry mission, and constantly promote the development of China's commercial aerospace industry and build China's commercial aviation together with constant perseverance and perseverance A new era of development.
