Forecast methodology, accuracy, and satellite coverage.
How does Vega forecast interference?
Vega combines three data sources:
- Real-time orbital tracking — TLE data updated daily
- Frequency allocation databases — Regulatory filings and spectrum assignments
- Geospatial coverage analysis — Calculate when satellite footprints overlap
We propagate satellite positions forward in time, identify which satellites share spectrum with yours, and calculate when their ground coverage footprints will overlap.
How accurate are the forecasts?
Forecast accuracy depends on TLE freshness. For 1–3 day forecasts with daily TLE updates, orbital position accuracy is typically within 1–2 km. Accuracy degrades beyond 7 days as orbital perturbations accumulate. Frequency mappings are tagged with confidence scores based on data source quality.
How far in advance can you predict interference?
We provide 7-day rolling forecasts, updated daily as new orbital data becomes available. Forecasts beyond 7 days are possible but accuracy degrades due to orbital perturbations, atmospheric drag variations, and potential satellite maneuvers.
What satellites does Vega track?
We track all active satellites with published TLE data and frequency allocations. This includes commercial communications constellations, government satellites with public spectrum filings, and amateur radio satellites. We currently have orbital data for over 11,000 active satellites.
Can I track satellites in any orbit?
Yes. Vega supports satellites in all orbit types: Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geostationary Orbit (GEO), and Highly Elliptical Orbits (HEO). Our orbital mechanics calculations handle all standard orbit geometries.
What if my satellite performs a maneuver?
Satellite maneuvers aren't reflected in TLE data until after they occur. If your satellite performs a planned maneuver, forecasts will be inaccurate until fresh TLEs are published (typically within 24–48 hours). We recommend running a new analysis after maneuvers.
