Rincon Research’s AstroSDR is a complete RF payload: software-defined radio (SDR), FPGA signal processor, ARM processor, and data storage. AstroSDR combines state-of-the-art capabilities with a flexible design, resulting in a compact, efficient solution for multiple mission requirements.

High-bandwidth cross-links, command and telemetry links, store-and-forward RF collection, data compression, and digital signal processing (DSP) in a field-programmable gate array (FPGA) are all achievable with AstroSDR.

AstroSDR can operate autonomously as a standalone system or as an element in a large bus. AstroSDR supports the Space Plug-and-Play Architecture (SPA) standard to allow command, control, and telemetry functions via an on-bus SPA network.

For applications that don’t require radiation-hardened, industrial parts, the commercial grade AstroSDR FPO offers additional power options at a lower cost.

For information about AstroSDR flight, see the AstroSDR Space Flight page.
