Abstract:

As high value geostationary earth orbit (GEO) satellites are under a range of threats, it is helpful to improve the survivability of satellite bus by exploring the technology system of on-orbit strong survivability (TSO2S2). Focusing on this, the concept of TSO2S2 is defined systematically. A protection system including warning and safety protection sub-system is built after the main threat sources are figured out. Firstly, 8 threats are divided into active type and passive type. The threat mechanisms are analyzed and the damage effects are evaluated using qualitative and quantitative methods. Secondly, an integrated space and terrestrial warning scheme is proposed and the equipment is designed which enabled 5 types of threats to be alarmed, including space debris, laser, et al. Finally, the protection technology and methods are summarized systematically, which can provide reference for the GEO satellite platform to improve the orbit safety.

Key words: satellite bus, damage effect, composite warning, security protection
