How To Track Visible Satellites Tonight
Find satellites visible tonight from your location using MySatVis pass calculations and visibility filters.
Fetch Satellite Data
Open the Satellites dialog, fetch current TLE data, then compute visibilities for your configured location and time range.
Filter By Visibility
Use Visible or Min El filters to focus on passes that rise high enough above your horizon to be practical to observe.
Apply And Follow Trajectories
Apply the selected satellites to overlay trajectory paths on the sky map and scrub the time slider to follow their motion.
Frequently Asked Questions
What does Min El mean?
Min El is the minimum elevation angle above the horizon used when filtering passes.
