The SPENVIS project is funded via the European Space Agency General Support Technologies Programme (GSTP) by the Belgian Federal Science Policy Office. It was initiated by the ESA/ESTEC Space Environment and Effects Section (TEC-EES). The project is developed by the Belgian Institute for Space Aeronomy (BIRA-IASB) under ESA contracts n°11711/95/NL/JG(SC)-WO1 and 19786/05/NL/GLC/jk.
