Aerospace generates big data and requires the application of big data throughout the development, operation, and release of results. Data is both the foundation of aerospace theory and the cornerstone of aerospace practice. Space exploration should explore the vast space where the scale is far greater than the earth, and the total amount is higher and the requirements are higher. If there is no timely and accurate big data support, even a decimal point error will affect the overall success or failure. Therefore, aerospace big data not only has the characteristics of general big data, but also requires high reliability and high value. Therefore, aerospace is the first area to propose the development of big data technology, and it is also the field that has the most achievements in big data.
The information blockade of aerospace technology in Western countries has not stopped China. China has opened up a new era in the space field with its own strength. The operation and visual effects of China's domestic aerospace visualization system have reached international advanced standards, and another perspective shows our confidence.
Taking the digital hail aerospace visualization system as an example, the system can be widely used in aerospace measurement and measurement, equipment-level display control systems; aerospace command and combat system simulation deduction, combat evaluation system; space operations command and display control system; joint command and combat simulation system ; spacecraft data analysis, condition monitoring system. The system has the following features:
First, a wide range of visualization space: covering the world, and even the universe; support offline deployment of global satellite / electronic maps and terrain elevation data.
The system can realistically present the Earth and space, accurately displaying the exact position of the sun, the moon, and even other planets according to the ephemeris, and there is real-time illumination and reflection in the space. The depiction of the earth, from the atmosphere, clouds, and the illumination of the ocean and land, the HDR effect of the sun, can be realistically presented. Support to bring in topographic maps, political maps, and even chart data, and can customize various display styles according to user requirements to achieve super cool effects.
The system is not limited to viewing the Earth at high altitudes, users can zoom in infinitely, support global 30M elevation terrain, and global HD satellite image maps, and provide a full set of offline data solutions and data update services.
Second, specific support for the aerospace business: spacecraft orbit calculation, spacecraft detection range display, data-driven spacecraft attitude change.
For satellite or even spacecraft orbit, on-orbit attitude, on-orbit mission, satellite's own state, the system provides a lot of support, and can be customized according to customer requirements. In addition to the situation display, the visual analysis of satellite acquisition data is also an important function supported by the system. Whether it is data map, data table or dashboard, it can display massive data efficiently.
Third, multi-dimensional perspective analysis view: time dimension (current situation monitoring, future simulation deduction, historical data playback), spatial dimension, logical dimension
In the large-scale satellite situation visualization system, the system also supports the derivation and analysis of complex task processes according to pre-set scripts, and can compare the real-time monitoring status with the planning data, and perform historical situation based on actual data. Playback.
Fourth, the powerful information plotting function plotting is a very important basic function for large-scale situation visualization. Whether it is two-dimensional or three-dimensional, the system provides very powerful and friendly basic plotting support, and supports the plotting Complex customization of objects. It can display no less than 100,000 mobile beacons in full screen at the same time, optimizing the display efficiency of massive beacons.
Five, two / three-dimensional linkage display operation, full touch support
The two-dimensional and three-dimensional dual interface systems are simultaneously displayed, collaboratively interacted, and the two-dimensional interactive operation is simple and clear, and the three-dimensional observation is intuitive and real, and supports full touch operation. The system provides a unique application interaction framework, supports multiple interactive control modes such as single screen, multi-screen, master-slave screen, etc. It has strong scene adaptability and can run in the command center big screen, special seat table, mobile command warehouse, A variety of equipment environments, such as a portable all-in-one.
Sixth, to achieve specific requirements deep customization
In terms of deep customization of user-specific requirements, the system provides SDK secondary custom development library and Puppet MasterTM, a behavior modeling tool that provides two-dimensional model objects.
"Aerospace industry is an important manifestation of the comprehensive strength of today's countries. It represents the comprehensive national strength and technological level of a country, and it also greatly affects the pride, cohesiveness and national spirit of the people. Therefore, the visualization of the aerospace field is not only Only technology is needed, but there must be dreams and national complexes!†Digital Hail CEO Deng Yuru said. Incorporating such an emotional Chinese core aerospace visualization system, how can it not exude dazzling charm and endless value!
