Iguassu Software Systems (ISS) excels in design and development of technology software applications and in aerospace marketing consultancy for Latin America and central Europe. Its core business is with the European Space Agency (ESA) and other space customers. During the transition period before full ESA membership (PECS 2005-2008), ISS was the most successful Czech space company, having been awarded 6 contracts, 2 of which through participation in international competitive tenders. Since the Czech accession to the ESA convention at the end of 2008, ISS is again in the forefront – the only Czech company to be awarded more than one project (in fact 3) in the ESA Czech industrial incentive scheme in 2009 and the only one to win work in competitive tenders with Astrium D and EOX in 2010.
