How the satellite pass predictor works
Enter a NORAD catalog ID and observer latitude, longitude, altitude, and date range.
Tool Nova requests visual pass predictions from N2YO through a server route.
Review local start, maximum elevation, and end times for upcoming visible passes.
Frequently Asked Questions
Does this require an API key?
Yes. Add N2YO_API_KEY in Vercel environment variables. The key is used only on the server route.
Are these predictions exact?
Use them as practical predictions. Visibility depends on sky conditions, lighting, observer horizon, orbital updates, and local obstructions.
