Study on threats to security of space TT&C systems

Abstract

A space Tracking, Telemetry and Command (TT&C) system is a spaceflight support system and its security is of great significance. A framework of space TT&C system security threat assessment is proposed and it comprises of three aspects of factors: attack severity, value of asset and probability-to-succeed. An approach of qualitative gradation is introduced in the assessment. Based on the security threat assessment framework, threats to the security of space TT&C Systems during confrontation are analyzed. The analysis shows that threats of physical attacks on ground facility, RF jamming and High Power Microwave (HPM) weapon attack on satellites are outstanding and corresponding Protection measures are demanded. © 2013 Tsinghua University Press, and Springer-Verlag.
