The European Satellite Navigation Program : policy analysis and recommendations for the future
The European Satellite Navigation Program is a case study that combines Technical / Public / Private aspects in an integrative way. Therefore, it is a sound case for a TPP thesis candidate. This thesis analyzes the European Union policies for the Galileo program, Europe's bid to have its own Global …
