PW-Sat is a series of Polish CubeSats designed and built by students at the Warsaw University of Technology in conjunction with the Faculty of Power and Aeronautical Engineering of Warsaw University of Technology, the Space Research Centre of Polish Academy of Sciences, and the European Space Agency. As of January 1, 2024, there have been 2 PW-Sats with a third in development. The first PW-Sat was the first Polish artificial satellite[1] which was launched 13 February 2012 from ELA-1 at Guiana Space Centre aboard Italian-built Vega launch vehicle during its maiden voyage.[2] After their graduation, the team that developed the original PW-Sat have also worked to develop the subsequent missions, establishing a private company named PW-Sat to design and manufacturer the PW-Sats, all of which test novel deorbiting methods, with the overall goal of the program to develop solutions to space debris.[3][2]
