Sub-100m orbital accuracy from public TLEs — validated on 42 million trajectories.
Sub-100m orbital accuracy from public TLEs — validated on 42 million trajectories.
THOR SPACE achieves 90–100 m position accuracy at 24 hours using only public TLE data — where legacy propagation diverges to 10–80 km. Validated across LEO, SSO, MEO and GEO on 42 million trajectory comparisons and 40,000+ objects, this is the first TLE-based engine to break the 100-meter automation threshold. No proprietary sensors. No GPU. Standard CPU, under 15 minutes.
THOR SPACE is a fully software-based system deployable in cloud, on-premise or air-gapped environments. It processes the entire 40,000-object catalog on standard hardware with no dependency on US infrastructure, no export-controlled components, and no external sensor network. European IP. Full algorithmic transparency. Designed for sovereign SSA from day one.
THOR SPACE does not just display predictions. Every important run produces sealed evidence: manifests, SHA-256 hashes, Merkle roots, replay paths and audit-ready reports. Operators get decision-grade outputs — not raw alerts — so they can prioritize what matters, justify actions, and reconstruct any decision after the fact.

At the critical 24-hour horizon, THOR SPACE maintains 90–100 m accuracy while SGP4 diverges to 10–80 km. Validated on real ESA operational events, including a Sentinel-2A conjunction where THOR predicted the time of closest approach within ±2.1 seconds — 85× better than SGP4.
Where SGP4 becomes operationally useless after 6–12 hours, THOR SPACE extends reliable prediction to 96 hours. At 96h, THOR holds 4.8–6.0 km accuracy versus ~120 km for SGP4 — a 20–25× advantage that turns reactive screening into predictive operations.
Higher precision means fewer unnecessary alerts and fewer wasted maneuvers. THOR SPACE reduces false positive conjunction events by 70%, freeing analyst time and cutting operational costs for mega-constellation operators managing thousands of close approaches per week.
The harmonic propagation engine estimates orbital states across 6h to 96h horizons, then automatically screens for close approaches, ranks conjunction events by severity, and delivers prioritized risk views — fleet-wide or satellite-level. Operators focus on what matters instead of drowning in alerts.
Every critical run is sealed with manifests, Merkle proofs, SHA-256 hashes, timestamped logs and replayable evidence bundles. Teams can review what was predicted, what data was used, and whether the output supports action — days, weeks or months later. Built for operators who need to prove, not just predict.
THOR SPACE runs on CPU-only hardware with no external sensors, no GPU and no privileged data feeds. It processes 40,000 objects in under 15 minutes and deploys anywhere — cloud, on-premise, classified networks or fully air-gapped facilities. Customers keep full control of their data boundary.
