PoSAT-1
PoSAT-1 (OSAT-OSCAR 28, OSCAR 28, PO 28, 1993-061G), the first Portuguese satellite, was launched into orbit on 26 September 1993, on the 59th flight of the Ariane 4 launch vehicle. The launch took place in the Centre Spatial Guyanais, French Guiana. About 20 minutes and 35 seconds after launch, at an altitude of 807 km, PoSAT-1 separated itself from the launch vehicle.
