In the competition organised by ESA (European Space Agency competition, link to competition: and, which is called CanSat teams made of 4-6 members have to build an own satellite, which is taken by a dron or a rocket to a height of up to 2,000m. It is an international competition, rather European. In the European final, each country is represented by maximally one team (some countries have no representation at all and have to fight in a barrage for place in final round). After passing through two rounds of national competition, the Hatalom team from Opatov Grammar School became the team representing the Czech Republic. The European final will take place from 27 June to 1 July in the Azores in Portugal.

The final round, which took place at the IQRF Summit 2018, was attended by the solvers of the two best projects selected from the projects submitted to the final.

Both projects came from the V?B - Technical University of Ostrava. Teaching and IQRF projects have many years of tradition and support here.

The winner has won development tools for IoT applications ...

IBM joins IoT alliance in CZ: More than 100 entities trust in Czech technology for the Internet of Things

The conference on the Internet of Things ? the IQRF Summit 2018 ? that has just taken place was an opportunity for visitors to see what Smart City, Smart Building, and Industry 4.0 projects companies are working on, and how. All those presentations here shared one common denominator: they all either use the IQRF, the Czech wireless technology, directly in their products or build on it in overarching systems. At the summit, the IBM announced that it was joining the IQRF Alliance as it was keen to become a major strategic partner for other members.
