PDC Sirius Solid-State Data Recorder: Reliable Onboard Storage for Space Missions

The PDC Sirius Solid-State Data Recorder (SSDR) is a radiation-tolerant storage solution designed for demanding spaceborne data acquisition, processing and storage applications.

Built around a ruggedised 3U SpaceVPX module aligned with SOSA standards, Sirius combines high-speed performance, substantial storage capacity and a compact architecture for modern spacecraft.

The PDC Sirius SSDR provides a robust onboard data-storage platform for capturing, buffering and managing mission data before transmission.

Its radiation-tolerant design supports operation in demanding space environments, while its 3U SpaceVPX format simplifies integration into modular spacecraft and payload architectures.

Sirius is designed in alignment with SOSA standards, helping system integrators develop interoperable and scalable platforms.

The product family is available with PCIe 2.0 x4 connectivity and storage capacities from 2.5 TB to 10 TB, allowing the recorder to be selected according to mission data rates, storage requirements and available system resources.

The PDC Sirius Solid-State Data Recorder can support:

• Earth observation and remote-sensing satellites.
• Scientific spacecraft and research missions.
• High-resolution imaging and video payloads.
• Radar and synthetic-aperture radar data recording.
• Hyperspectral and multispectral instrumentation.
• Satellite communications and signal-processing systems.
• Autonomous spacecraft and robotic exploration.
• Defence and intelligence payloads.
• Spaceborne data acquisition and temporary data buffering.
• Distributed avionics and modular SpaceVPX architectures.
