In recent years, with the development of space technology, China aerospace industry development is facing the trend of the development of civilian, especially for the small satellite and the application of satellite data will be used in the industrial market growth space is the largest and most promising parts. This paper will be the background of spark satellite, according to its own requirements and then analysis of the current integrated satellite ground control system operation characteristics, and based on the multi-satellite multi-task, the design idea and implementation strategy of the integrated operation of the ground-based control system of the spark satellite are presented by using the real-time satellite data. The use of satellite data fusion approach, more accurate for the ground control system services, and ultimately to the task planning command and control strategy based on the use of configuration parameters with mobile variable, graphical interface intuitive operation and display, intelligent and fast task Instruction sequence and configuration parameters generated by the system for the spectrum of spark satellites in orbit to provide fast, simple, intelligent ground task support. Through the system design, that is for the follow-up small satellite constellation ground operation control system and the data fusion between the satellite and ground to provide a generic prototype reference.

Bubble dynamics plays a significant role in a wide range of industrial fields, such as food, pharmacy and chemical engineering. The physicochemical properties of complex fluids can greatly affect the speed with which bubbles rise, and the lifetime of bubbles, which in turn can affect the efficiency of food and drug manufacturing and also sewage purification. Therefore, it is of great scientific and practical significance to study the influence mechanism of nanoparticles and surfactants on bubble rising and impact in a complex fluid interface. This paper selects a mixed dispersion liquid of nanoparticles (SiO2) and a surfactant (SDS) as the objects of the study, observes in real-time the entire processes of bubbles rising, impact at the gas-liquid interface, and rupture, and analyzes the dynamic mechanism of bubble impact in a complex fluid interface. By analyzing the morphological changes of the rising bubbles, the rising velocity and the lifetime of the bubbles, it is found that the surfactant molecules are distributed in the ultrapure water liquid pool and the liquid film surrounding the bubbles. Such distribution can reduce the viscoelasticity between bubbles and the liquid surface, and lower the surface tension of the liquid, which can reduce the rising velocity of bubbles, delay the drainage process of bubbles on a liquid surface, and enhance the lifetime of bubbles. If the liquid surface is covered with nanoparticles, a reticulate structure will be formed on the bubble liquid film, which can inhibit bubble discharge and prolong bubble lifetime. In addition, the influence of such a reticulate structure on liquid surface tension is limited and its function is far smaller than a surfactant.
