Uncrewed ground vehicle on open terrain, a representative host platform for PERSEUS
Trusted Autonomy · Interoperability Layer

Decision advantage for uncrewed systems in contested environments.

PERSEUS is a platform-agnostic trusted-autonomy and interoperability layer for uncrewed ground vehicles. It turns a host platform’s own sensor feeds into doctrine-driven, explainable, human-supervised tactical guidance, and keeps a full, replayable record of every decision.

What PERSEUS is

A trust layer between the platform and the mission.

PERSEUS installs on a Linux compute node aboard a host uncrewed ground vehicle. It ingests the platform’s own sensors and state, builds a sensor-neutral environment and trust model, and applies structured military doctrine to recommend, never command, the next tactical action.

Perceive

Sees with the platform’s own eyes

No proprietary sensor kit required. PERSEUS normalises the host’s cameras, EO/IR, LiDAR, radar, odometry and GNSS into one sensor-neutral picture, and tracks the trust, freshness and uncertainty of every input.

Reason

Decides by doctrine, not black-box AI

Every recommendation passes 13 constraint gates and weighted, doctrine-tiered scoring. The logic is deterministic and explainable, the same inputs always yield the same advice, and every decision can be replayed and audited.

Supervise

Advises, the human and platform stay in command

PERSEUS publishes advisory guidance only. The host platform owns navigation, steering, braking, emergency stop and safety. Autonomy never exceeds human-supervised levels (LOI 0–4); PERSEUS never emits LOI 5.

The architecture

Three strictly separated subsystems.

A hard architectural boundary keeps perception, reasoning and execution apart, so each layer can be inspected, validated and trusted independently. Perception never plans. Reasoning never drives.

01 · Perception
EYES

Descriptive perception and environment interpretation. Builds terrain, occupancy, occlusion, exposure and blind-sector truth from the platform’s feeds.

  • Sensor-neutral environment model
  • Trust, freshness & uncertainty per input
  • No planning · no doctrine · no commands
02 · Reasoning
BRAIN

Doctrine-guided tactical reasoning. Generates candidate actions, filters them through constraint gates, scores by doctrine tier, and explains its choice.

  • 13 constraint gates · weighted scoring
  • Degraded-GNSS & comms-loss policy
  • Correction ledger & full audit trace
03 · Execution scaffold
BODY

Downstream execution scaffold that hands bounded, advisory guidance to the host platform across the standards-based interoperability boundary.

  • SAE AS-4 JAUS mobility messages
  • Host accepts or rejects guidance
  • Never re-implements doctrine reasoning
Advise, don’t drive.  PERSEUS may plan bounded tactical guidance. It does not control propulsion, steering or actuators, and has no effector or weapon output surface at any architectural layer. Path-following and low-level mobility remain the host platform’s responsibility.
Built for the degraded fight

Keeps reasoning when GNSS and comms don’t.

Contested environments break the assumptions civilian autonomy is built on. PERSEUS treats degraded navigation, jammed links and spoofed positioning as the normal case, and governs its behaviour by explicit doctrine policy.

  • GNSS-degraded / denied reasoning, navigation-trust state is a first-class input, not an afterthought.
  • GNSS spoofing suspicion, an explicit signal that shapes advisory caution.
  • Comms-degraded policy, bounded, doctrine-governed behaviour when the link is intermittent or lost.
  • Cooperative sensing, ingests peer observations, but local truth wins on conflict.

NATO DIANA 2027 · Multidomain Autonomy

Positioned for the multidomain autonomy challenge.

PERSEUS maps directly to the NATO DIANA 2027 Multidomain Autonomy of Uncrewed Systems challenge, resilient autonomy, host-agnostic integration, trusted explainable reasoning and replayable evidence. See the capability-by-requirement breakdown.

Why reviewers trust it

Credibility, stated honestly.

We present PERSEUS as a proof-of-concept with a mature, implemented core, and we are precise about what is proven today versus what the pilot phase delivers.

Advisory-only

Every contract carries advisory_only=true. Zero commanding fields anywhere in any output.

Deterministic

No hidden ML, no opaque inference. The same inputs always produce the same, replayable advice.

Standards-aligned

SAE AS-4 JAUS, cross-validated against an independent decoder. Aligned, not yet certified, and we say so.

Evidence-backed

Every demo emits a timestamped, SHA-256-anchored evidence pack you can verify independently.
