可移动式卫星地面数据加解密处理系统设计

Design of Mobile Satellite Ground Data Encryption and Decryption Processing System

针对现有卫星地面数据加解密处理系统在灵活性、适应性、稳定性、集成性、兼容性等方面不能较好地兼顾等问题,结合数据处理的任务需求和作业条件,提出并设计一种可移动式的、能够同时处理多颗卫星多路数据的新型通用化、集成化数据处理系统。系统硬件选用高配置加固计算机,软件开发基于多线程并行计算和模块化设计思想,采用C++的Boost库编写。经验收测试,系统能灵活适应固定站和机动站的作业环境,性能满足规定指标要求,圆满完成了多颗卫星型号的多路数据处理任务。

In order to solve the problem that the existing satellite ground data encryption and decryption processing system can not take into account a lot of performances,such as flexibility,adaptability,stability,integration,compatibility and other aspects,according to the task requirements and operational conditions of data processing,a mobile,universal and integration data processing system is proposed and designed,which can be used to process multiple satellites data simultaneously.Unlike traditional designs,the new system uses ruggedized computer,the software development is based on multi-thread parallel computing and modular design ideas,and is written with C++Boost library.The acceptation test demonstrates that this new system can adapt to the operating environment both fixed-station and mobile-station flexibly,and achieve multiple data processing missions for multiple satellite models successfully.
