TUBSAT was a German remote sensing microsatellite. The payload consisted of a triple-lens camera system: a wide angle 16 mm lens with a black and white CCD chip, a standard angle 50 mm lens with color CCD chip, and a 1,000 mm telephoto lens with a black and white CCD chip.

The satellite has a cubic shape of 32 cm in dimension. It is mainly used for high resolution earth observation tasks. This is done in a live TV mode with a three head camera system with different focal lengths. The spatial resolutions of the Earth pictures are respectively 370 m, 120 m, and 6 m. The pictures can be received with a standard satellite dish with a minimum of 3 m in diameter. Users transmit the coordinates of a point on the Earth and the satellite computes the needed attitude control actions to track this point during the crossing.
