LETO (Low-Earth Triage & Operations) links live disaster feeds with satellite access timelines for Australia and Africa. Mission control for satellite emergency response. Fuse live disaster feeds with satellite access windows, revisit timelines, and downlink planning. --- ## What is LETO? **LETO** is a browser-first mission control dashboard for satellite emergency response. It answers the critical question: > *"Given my satellites and ground stations, which incident can I observe first — and how quickly can I get the data down?"* Built for satellite imagery analysts, emergency coordinators, and field operators who need rapid triage under time pressure. ### Key Capabilities | Feature | Description | |---------|-------------| | 🔥 **Live Feeds** | NASA FIRMS (fires), GDACS (floods/cyclones), NASA EONET (natural events), USGS (earthquakes) | | 🛰️ **Orbit Propagation** | SGP4/TLE propagation for real satellites; circular orbit generator for synthetic constellations | | 🗺️ **Access Windows** | AOI imaging passes, station contact windows, revisit gap analysis | | ⏱️ **Time-to-Information** | TTFO (time to first observation) + TTDL (time to downlink) per incident | | 📊 **Serviceability Scoring** | Weighted 0-100 score combining observation latency + downlink latency + gap coverage | | 🎯 **Interactive Map** | Satellite basemap with ground tracks, footprints, AOI boundaries, incident markers | | 📈 **Gantt Timeline** | Visual pass schedule with access windows, downlink windows, station contacts | | ⚙️ **Scenario Editor** | Configure AOIs, satellites, stations, horizons, timesteps in real-time | --- ## Architecture ``` ┌─────────────────────────────────────────────────────────────────┐ │ DATA SOURCES │ │ NASA FIRMS ──►│ │ │ GDACS ───────►│ ┌─────────────┐ ┌─────────────────────┐ │ │ NASA EONET ──►├──►│ Ingestion │───►│ Satellite Engine │ │ │ USGS ────────►│ │ + Cache │ │ (SGP4/Access calc) │ │ │ │ └─────────────┘ └───────────────────── …
