Onboard Defense.

Guard the spacecraft.

The counter-autonomy layer that runs on the spacecraft itself. It watches the bus and the onboard AI for the kinds of attacks that turn an autonomous satellite into someone else's asset.

Capabilities

Bus IDS · CSP

Command injection detection.

Anomaly detection across the Cubesat Space Protocol command bus.

Bus IDS · CAN

CAN-level monitoring.

Power and attitude attack detection on the CAN bus.

Telemetry spoofing

False data, caught early.

Detects forged telemetry before it reaches the operator.

Onboard-AI defense

Adversarial input blocked.

Adversarial patches, visual prompt injection, and supply-chain backdoor triggers.

Unsafe tasking

Refuse the bad command.

Block tasking that would violate the spacecraft's safety envelope.

Safety envelope

Emergency stop.

Halt autonomous actions before they reach the actuators.

Status

Demonstrated against a simulated spacecraft. Bus attacks detected with correct type and severity at sub-10-second latency.

Maturity · TRL 4 · Validated against real captured satellite downlink RF.
