SDR-2104

Advanced Radio for Space Missions

The SDR-2104 is a flight-qualified software-defined radio designed for high-data-rate communications across LEO through lunar missions. It supports comms, sensing, and ranging within a reconfigurable architecture, enabling mission adaptability without hardware redesign.

Key features
and benefits

Fly With Confidence

Reduce integration risk with a proven architecture. High-performance FPGA-based design with four transmit and four receive channels.

Support Multiple Mission Types

Enable communications, sensing, and ranging within a single system. Flexible RF and baseband processing supports multi-function operation.

Adapt On Orbit

Update performance as mission needs evolve. Reconfigurable FPGA supports waveform, frequency, and processing updates post-launch.

Integrate Quickly

Accelerate deployment within existing payload architectures. SpaceVPX (VITA 78.0) compliant form factor and standard interfaces.

Enable Waveform Flexibility

Support mission-specific and standards-based communications. Compatible with DVB-S2X, CCSDS, and custom waveform development, with custom IP integration via CesiumAstro’s Board Support Package.
