Space-Based Measurement and Control System: Satellite Communication Channel Optimization and Network Security Synergy Technology

This study addresses the problems of limited satellite communication channel resources and network security threats in space-based measurement and control systems. A synergistic technology scheme for channel optimization and security protection is proposed. A distributed testing and verification platform is constructed to realize the collaborative deployment of dynamic channel allocation and security protection mechanisms. The verification results show that the scheme improves the channel utilization rate by 45.2 % and the security threat detection accuracy by 97.3 % under 200 concurrent measurement and control services. The average response delay is reduced to 82ms. During the three-month actual operation verification, the system availability reaches 99.98%, and 152 security events are successfully handled, demonstrating the practical value of the synergistic technology for satellite communication channel optimization and security.
