Platform Features

Everything an SSA
researcher needs.

From real-time visualization to scientific analysis tools — all in one open platform, free forever.

🌍
Real-Time 3D Globe

34,000+ objects rendered in WebGL at 60 FPS using GPU instanced mesh. Color-coded by type. Click any object for live telemetry — altitude, speed, lat/lon updated every 5 seconds.

SGP4 Propagation
⚠️
Conjunction Analysis

Detect close approaches between any satellite and the full catalog. Two-pass scan over a 1–7 day window. Returns miss distance, relative velocity, and probability of collision.

Chan Pc Model
📉
Orbital Decay Predictor

Estimate re-entry dates using BSTAR drag term and numerical integration. Shows altitude decay sparkline over time with confidence rating. Best for objects below 600 km.

BSTAR Numerical Model
📡
Pass Prediction

AOS/LOS timing for all 5 ISRO ISTRAC stations. Shows max elevation, azimuth at rise/set, duration, range, and sunlit indicator. Predict up to 72 hours ahead.

🔌
REST API

Every feature is accessible via API. Query satellite positions, run conjunction analysis, get decay predictions. Integrate directly into Python, MATLAB, or Julia scripts.

No Auth Required
🔄
Auto-Sync Pipeline

GitHub Actions cron pulls fresh TLE data from Space-Track.org twice daily at 11:30 IST and 23:30 IST. Smart epoch deduplication builds a historical archive automatically.
