[3][4][5][6][1] The launch took place in the Centre Spatial Guyanais, French Guiana.

[4] The total cost was around €5 million, about €3 million paid by the Portuguese Government and €2 million by the Portuguese companies involved (Po-SAT consortium: Instituto Nacional de Engenharia, Tecnologia e Inovação (INETI), EFACEC, ALCATEL, Marconi Company, OGMA, Instituto Superior Técnico (IST), University of Beira Interior (UBI) and CEDINTEC).

The responsible for the project was Fernando Carvalho Rodrigues, known as the father of the first Portuguese satellite.

At the top of the satellite there are sensors for attitude and the stabilization mast, essential tools for PoSAT-1 to maintain correct orbit.

Four solar panels are mounted on the lateral sides of the structure of the satellite, forming a parallelepiped, which are the source of energy for all on-board systems.
