OOV-CUBE (TUBSAT-30) is an amateur radio satellite from Germany, launched on July 9, 2024 from Kourou, French Guiana. It is in a low orbit, 541 to 572 km above the ground, and goes around the Earth every 95.8 minutes: 15.0 times a day, at 7.58 km/s (27,300 km/h).
The gold ring is its orbit, and the line drops to the point on the ground under it. Inside the white circle it is above the horizon. Drag the globe to turn it, pinch or use the buttons to come closer; the target button brings you back to the satellite. The 2D map shows its path over the ground for the next lap: gold where it is in sunlight, dashed where it is in Earth’s shadow.

It passes straight overhead only between latitudes 62° north and 62° south, and rises above the horizon as far as about 85°. Nearer the poles than that it is never in the sky.
A satellite shows only when your sky is dark and it is still in sunlight: in the hours after dusk and before dawn.
The app works out its passes over your exact location, alerts you before one, and leads you to it with an arrow in the camera view.
Orbit measured November 13, 2026, from CelesTrak. Heights are above the ground at the equator. Page updated November 14, 2026.
The map on this page shows where OOV-CUBE (TUBSAT-30) is at this moment, the path it will follow over the ground for the next lap, and the part of the Earth it is above the horizon for. It is worked out from the latest tracking data.
Between 541 km at its lowest and 572 km at its highest, above the ground.
About 7.58 km/s, which is 27,300 km/h. One lap of the Earth takes it 95.8 minutes, so it goes around 15.0 times a day.
