Preface
The last global networking satellite of Beidou-3 was ignited and launched successfully at the Xichang Satellite Launch Center on June 23, 2020.
After Beidou provides global services, all walks of life are more confident in applying Beidou and fully deploy the Beidou industry. For example, business integration with traditional applications such as transportation, agriculture, forestry, animal husbandry and fishery, power and energy, disaster reduction and relief, and financial communications has been deepening. At the same time, with the advent of the 5G commercial era, Beidou is accelerating its integration with new technologies such as next-generation communications and artificial intelligence to enhance its comprehensive national defense capabilities.
Digital twin analog satellite launch interface preview
HT for Web independently developed a powerful 2D and 3D rendering engine based on HTML5, which provides rich display effects for visualization. In 2D configuration and 3D configuration, Hightopo (hereinafter referred to as HT)'s HT for Web product has a wealth of configuration options. This article will introduce a Beidou-3 satellite built using HT's rich 2D/3D configuration Successfully launched visualization system case.
The Beidou satellite navigation and positioning system is a regional active 3D satellite positioning and communication system (CNSS) independently developed by China . It is the third mature satellite navigation system after the United States GPS and Russian GLONASS. It is a regional navigation system that provides satellite navigation information around the clock. The system mainly provides efficient navigation and positioning services for transportation, meteorology, petroleum, marine, forest fire prevention, disaster forecasting, communications, maritime operations, logistics management and other industries, and its application prospects are very broad.
The construction of digital twins is a major disruptive innovation in intelligent management services. Everything has a virtual image in the digital world. Information is visible, trajectory can be followed, status can be checked, virtual and reality are operated synchronously, scenarios are blended, the past can be traced, and the future can be expected , Knowing the cold and warm at the moment, seeing the small and knowing the work, seeing the beginning and knowing the end, the entire launch trajectory is under control.
Using digital twin technology, through continuous collection and intelligent analysis of operating data, the best time point for maintenance can be predicted.

The center is a 3D scene, and the data on both sides is composed of 2D panels, which can rotate, pan and zoom the scene 360 degrees. The data panel shows some related simulation information of rockets and satellites.
Through the large visual screen, from the full layout, designated areas to designated key equipment, it comprehensively, centrally and dynamically displays the intelligent management and control of Beidou-3 satellite and rocket launching, such as monitoring management, route management, operating data and equipment status. Achieve all-round and full-cycle monitoring of the operating status of the "digital twin", and provide accurate and real-time information and data for the operation, maintenance, and risk investigation of aerospace engineering.
5 steps to show the rocket lift-off process
- Stabilizer ignition and launch deployment
- Booster ignition, acceleration, separation
- The second stage rocket ignites and releases thrust
- The fairing is stripped and the secondary rocket is separated
- Strip the satellite into orbit and start operation

The role of the rocket is to transport the load to a certain height, and the role of the fuel is to provide energy. Therefore, fuel is the key. The rocket is a fuel-burning tool. It ignites the fuel and pushes the various exhaust gases generated by the fuel combustion backwards to achieve a boosting effect, so that you can move forward. The figure below is a simulation query panel for fuel remaining data .
Simulated fuel remaining data
List record is a document of process status and process results, recording every step of the production and quality management process. It is an important part of the quality management system document. According to the above-mentioned characteristics of the record, the record plays an important role in the quality management system of the organization. The main purpose of recording is to ensure the traceability of the production process.
Records are used as basic and basis documents to fully reflect the process and results of product quality formation and the operating status and results of the quality management system. Space launch also needs to record process events. The following are the different stages of the satellite launch process. Click [Show] to display the scene interface at a certain point in time.

Realize value
Through the intelligent research of satellite navigation special projects, my country has realized the independent control of basic satellite navigation products, formed a complete industrial chain, and gradually applied to various fields of national economic and social development. With the development of technologies such as the Internet, big data, cloud computing, and the Internet of Things, the embedded and integrated applications of Beidou's basic products have gradually strengthened, resulting in significant integration benefits. Civilian high-precision positioning and navigation services are the core of Beidou's business .
Many modern agricultural methods such as planting, spreading, harvesting, and grazing also require precise locations provided by Beidou. Over the years, research on various earth sciences such as gravity field, magnetic field, plate motion, rotation, earth's centroid, ocean tide, glacier, polar regions, and atmospheric sciences have reached unprecedented heights. Satellite navigation systems such as Beidou have contributed indispensably. The emergence of Beidou has greatly improved the accuracy of large-scale construction of infrastructure powers, up to the millimeter level. This not only ensures the super high quality of the project, but also greatly reduces the huge expenditure of traditional surveying methods to achieve similar accuracy.
to sum up
In summary, promoting the integration of satellite navigation and emerging technologies, such as 5G, mobile communications, big data, and the Internet, will surely bring new and more models, formats and economic growth points. It can be said that the future of Beidou is limited to human imagination. Today's Beidou navigation system has quickly entered a new era, and my country's integrated navigation and positioning facility service system will be established in the future.
Adhering to the development concept of "China's Beidou, the world's Beidou, and the first-class Beidou", we vigorously promote the new era Beidou spirit of "independent innovation, open integration, unity, and the pursuit of excellence". It will be built by 2035 to be more ubiquitous, more integrated, A smarter national integrated positioning and navigation timing system will provide core support for future intelligent and unmanned development, continue to promote system upgrades, integrate new-generation communications and other emerging technologies, and build coverage of the sky, ground and sea, with unified benchmarks, high precision, and high Intelligent, high-security, and high-efficiency spatio-temporal information service infrastructure.
