PARLEY AI Orbital Negotiation System

PARLEY is a multi-agent orbital conjunction negotiation system built for the Band of Agents Hackathon 2026. It automates one of the most consequential decisions in space operations — who maneuvers, when, and by how much — without human intervention. The system runs six autonomous agents, each with a single responsibility: Sentinel monitors conjunction data and fires the first alert when collision probability crosses the safety threshold. Oracle enriches that alert with orbital parameters — fuel reserves, delta-V capacity, approach geometry — and recommends which satellite should maneuver. Operator Alpha and Operator Bravo represent each satellite operator. They negotiate directly, proposing burns, countering, and converging on a maneuver plan. Arbiter, running on an independent model, validates the agreed plan against coordination norms and issues the final verdict. Archivist seals every event into a hash-chained, tamper-proof audit trail — nothing can be altered after the fact. In a live test run, Sentinel flagged a critical conjunction between STARLINK-4412 and ONEWEB-2201 with a collision probability of 0.00018 (nearly double the 0.0001 threshold) and a miss distance of 42.3 meters. Oracle recommended ONEWEB-2201 as the maneuvering party based on its higher fuel reserves and delta-V capability. The operators negotiated and agreed on a 0.38 m/s retrograde burn, achieving a 500-meter miss distance and cutting collision probability by over 99%, to 1.4×10⁻⁶. Arbiter certified the plan, and Archivist sealed the full sequence into an immutable audit trail. PARLEY runs on Claude Sonnet 4.6 via the AI/ML API, with Featherless AI powering the independent Arbiter model, orchestrated through Band.ai's agent SDK. Every agent call is real, logged, and traceable. From detection to certified resolution — autonomously, in under a minute.
