25758 - TUBSAT

TUBSAT was a 45 kg German remote sensing microsatellite that was launched from Shriharikota by an Indian PSLV-C2 rocket at 06:22 UT on 1999 May 26. 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 spatial resolutions of the earth pictures are respectively 370 m, 120 m, and 6 m. Initial orbital parameters were period 99 min, apogee 730 km, perigee 719 km, and inclination 98.4 deg.

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.
