ECHO Software Defined Radio (SDR)

The ECHO Software Defined Radio is TALOS’s versatile SDR module designed for CubeSat satellite payloads performing IoT signal collection in low Earth orbit. It serves as the core receiver for the TALOS satellite constellation’s ground-sensing capability, capturing uplink signals from IoT tags across the coverage area.

The ECHO SDR leverages a software-defined architecture that allows in-orbit reconfiguration and protocol updates, ensuring long-term adaptability as system requirements evolve. Its design prioritizes low power consumption and compact form factor for integration into 1U–3U CubeSat platforms while maintaining high sensitivity for reliable reception of weak signals from small ground-based IoT devices.

The module has been integrated into the RAVEN microsatellite and the TALOS-I CubeSat constellation, both operating as part of the ICARUS 2.0 programme. It supports multi-channel simultaneous reception, enabling high-throughput data collection for dense IoT deployments.
