Sentinel Space today publicly introduced two products purpose-built for autonomous satellite constellation coordination: SYNAPSE, a distributed coordination engine, and SIMULACRUM, a high-fidelity digital twin simulation environment. Together they give constellation operators the ability to coordinate autonomously on orbit and validate that coordination before anything flies.
SYNAPSE is a distributed coordination engine designed to run adjacent to flight software on every node in a constellation. It operates with zero ground dependency, classifying events and selecting responses in sub-second timeframes across more than 20 event categories. The architecture scales from single-satellite missions to constellations of 1,000+ nodes without requiring a centralized command authority.
SIMULACRUM is a high-fidelity digital twin that mirrors the full SYNAPSE pipeline under physics-based orbital conditions. Operators use it to prove autonomous behavior before committing to orbit — running deterministic scenarios across conjunction events, proximity operations, electronic warfare, space weather, and other contested conditions. Every scenario executes the same pipeline that runs on orbit, ensuring simulation fidelity matches operational reality.
"The coordination bottleneck is the constraint on mission ROI," said Michael Knight, founder of Sentinel Space. "Ground-dependent coordination doesn't scale with proliferated constellations. SYNAPSE and SIMULACRUM eliminate that bottleneck — autonomous coordination that works on orbit, validated before it gets there."
Both products serve a dual-use architecture spanning defense, commercial, and insurance markets. Defense programs gain autonomous space domain awareness and contested-environment response. Commercial operators gain real-time constellation health management and automated anomaly resolution. Insurance underwriters gain quantifiable risk assessment through deterministic simulation campaigns. One platform, one codebase, configured per mission.
SYNAPSE and SIMULACRUM are available for demonstration and evaluation. To schedule a demo or begin an evaluation, contact our team through the request form on this site.
