Europe’s students and young researchers were challenged to design a smartphone app to take advantage of Galileo’s dual-frequency signals. Run by ESA in collaboration with the European Global Navigation Satellite Systems Agency – GSA – plus the European Commission with the support of Google, a total of five teams made it to the final of the Galileo smartphone app competition 2019 which took place at ESA’s ESTEC technical heart in the Netherlands on Thursday 18 April. This event was preceded by testing the performance of the competing apps in static, pedestrian and driving use modes.
