POSAT 1 was a Portuguese experimental microsatellite that was launched along with SPOT 3 (93-061A). It was intended to receive and retransmit images, to determine its own position with the help of the GPS system, and to experiment with signal compression techniques. It was built at the University of Surrey (UK) within a collaborative program in satellite technology between a consortium of Portuguese academia and industry and the University - managed through its technology transfer company, Surrey Satellite Technology (SSTL).
