The UPM-LBSat or UPMSat (Universidad Politécnica de Madrid Satellite) is a microsat built by the University of Madrid and CIDE, Spain. The 44 kg (47 kg before separation) satellite was launched on the Ariane-40 H10-3 V75 mission on the 7th July 1995 alongside Cerise on an ASAP platform, besides the primary payload Helios 1A, a military remote sensing satellite.
The orbit is 665 × 675 km inclined at 98.1 degrees. The satellite is box shapedwith dimensions 530 × 450 × 450 mm, generates 30W end of life DC power from its four solar panels (three Si, one GaAs), and carries fluid dynamics and micro-gravity payloads. A 200 kHz bandwidth UHF transmitter is also included for communications research. It is attitude stabilized using magnetorquers.
