Why TerraCube S1?

Modular by Design

Stackable GigE + SpaceWire backplanes let you build distributed arrays without rewiring buses.

Self-Reliant

Sensor health checks, auto-calibration routines, and radiation-tolerant firmware mean zero-maintenance deployments that can run for years on unattended power.

Edge Intelligence

Integrated TPU classifies spectra, terrain texture, or chemical signatures locally, slashing both latency and downlink budgets.

Rapid Integration

Designed for Caelum Space's Sentinel Autonomy System but compatible with ROS 2, DDS and PX4 bindings plus a C++/Rust SDK streamline payload scripting, while twin M12 rugged connectors ensure plug-and-play power/data.
