Calculate the next 24 hours for your selected satellite. The default viewing mask is 10 degrees, and the optical screening rule uses a Sun elevation of minus 6 degrees.

Loading orbital tools. Positions are calculated predictions, not live telemetry.

A candidate, not a guarantee

Pass cards distinguish the geometric interval above the mask from candidate optical intervals. Calendar exports are one-time predictions and do not update automatically. Recheck before observing.
