Overview of deep space exploration space transportation systems and control technology

Abstract

Diversification of deep space exploration mission is causing a new development of space transportation systems, autonomous GNC technologies is playing key role for deep space exploration. In this paper, domestic deep space exploration program and deep space exploration space transportation systems were reviewed. Then the trend about deep space exploration spacecraft launch vehicle is analyzed. The problems faced by deep space exploration space transportation systems autonomous GNC technology are proposed and the key technical analysis is carried out providing a reference for deep space exploration spacecraft advanced guidance and control technology.

Joint source–channel rate allocation with unequal error protection for space image transmission

“…On the other hand, the images to be transmitted are of immense amount, especially for real-time transmission cases, which puts rigorous pressure on the efficiency of the communication links. 1…”

“…On the other hand, the images to be transmitted are of immense amount, especially for real-time transmission cases, which puts rigorous pressure on the efficiency of the communication links. 1 Traditionally, high efficient image compression algorithms including lossless and lossy ones and advanced channel coding techniques are employed to accomplish the high reliable and efficient space image transmission. In the system design, the source coding module for image compression and the channel coding module for error protection are implemented separately.…”
