How To Use MySatVis
Learn the core controls in MySatVis, including observation time, layers, location, and satellite selection.
Start With Location
Set your observer location first so altitude and azimuth calculations match your sky. You can enter coordinates manually or use device location services.
Adjust Observation Time
Use the time controls to move through the selected viewing window. Switch between local and UTC time display depending on your workflow.
Enable The Layers You Need
Turn on satellites, trajectories, constellations, and star labels from Layers. Keep only needed overlays active to reduce visual clutter.
Frequently Asked Questions
Do I need an account to use MySatVis?
No account is required for the core sky map and visibility tools.
Why does the map look different when I change time?
Celestial object positions and satellite passes are time-dependent, so the map updates as the observation time changes.
