基于IP组网的低轨航天器大容量文件传输方法

IP-Based Transmission Method for Large-size Files in LEO Spacecraft

空间科学的发展使航天测控中遥感和图像等数据量日益增大,如何实现天地间大容量文件的传输已成为一个重要问题。鉴于测控网正在向全IP化的方向发展,提出一种在IP组网基础上的低轨航天器大容量文件的传输方案,并就方案中文件的分块传输及卫星在测控站间切换时文件的续传等关键问题进行探讨。在此基础上,对提出的方案进行实验分析,验证了其可行性。

With the development of space science and exploration,the amount of remote sensing data and image data in aerospace TT&C increases a lot,and how to transmit large-size files between space and earth becomes an important issue.In view of the IP development direction of tracking network,a transmission method for large-size files in LEO spacecraft is proposed on the basis of IP networking.The sub-block transmission,transmission resuming at break-points after the satellite switching and other key issues are discussed.Finally,the experimental analysis is conducted on the proposed program to verify its feasibility.
