Full-Link Controllable SSD

The AS3 series offers full-link controllable storage systems centered on independently developed radiation-hardened SSDs and industrial-grade ruggedized SSDs. Through triple ruggedization technologies at the chip, firmware, and system levels, it delivers a high-reliability, predictable, and manageable intelligent storage solution for spacecraft in space environments.

Cost-Effective
By standardizing core components and configuration items through system-level design, the AS3 series effectively reduces additional cycles and costs caused by repeated modifications in production. Meanwhile, it adopts system-level ruggedization measures to ensure the on-orbit reliability of industrial-grade products, fully meeting the cycle and price requirements under current industrial mass production demands.

Full-Orbit Coverage
Specifically designed for space environments, the AS3 on-board storage system supports data storage needs of spacecraft and aerial vehicles operating from 300km Low Earth Orbit (LEO) to 36,000km Geostationary Orbit (GEO), adapting to diverse mission scenarios from near-Earth orbit to geosynchronous orbit.

Highly Integrated & Scalable
The AS3 system not only features large-capacity and high-speed data storage capabilities but also integrates data processing functions such as AES256/SM4 encryption and JPEG2000/JPEG LS compression. It can be expanded with AI computing boards, meeting the diverse needs of spacecraft in terms of data security, transmission efficiency, and complex mission processing.

Modular Design for Rapid Delivery
Both the hardware platform and software configuration items of the storage system have achieved platform-wide application within the company, with a product inheritance rate exceeding 85% and mass production realized. It can provide users with shorter delivery cycles, with a minimum lead time of 5 months excluding environmental testing.

On-Orbit Maintainable & Testable
The AS3 system integrates health status monitoring and on-orbit injection functions, enabling prime contractors to real-time monitor system conditions and flexibly update command data for on-orbit maintenance and iteration.

Multi-Dimensional Reliability Design
Reliability is ensured through multiple measures: critical status data is stored in single-event effect (SEE)-immune components, supplemented by SRAM FPGA refreshing, triple modular redundancy (TMR) design for key FPGA configuration registers, along with power supply detection, temperature detection, and DDR ECC. These collectively guarantee stable equipment operation.
