Since this July 25, the European global positioning system, called Galileo, has gone from having 22 satellites to 26. The total number of satellites that will make up the system will be 30 and the latest launches are planned for 2020, operating at an altitude of 23,222 meters (23kms) from Earth.
The Galileo positioning system began its commercial activity on December 15, 2016. The European Space Agency indicates that there are already more than 100 million electronic devices, which can work with Galileo.
