EU Transport Commissioner Jacques Barrot appointed Karel Van Miert, a former European commissioner, to help speed up decisions related to the multi-billion-euro push to rival the US Global Positioning System.
EU states such as Germany, Italy and Spain have fought in recent weeks over where to house infrastructure for the 30-satellite system, like control centres and headquarters for the building consortium.
They have also baulked at granting more funding for the project's development phase.
Germany, a large contributor to the project, has been one of the loudest protestors, refusing to finance further development unless it won an adequate share in the bidding consortium and a control centre base.
"Over the past few weeks, some decisions at industrial level have been delayed for various reasons, partly because of the complexity of the industrial organisation," the Commission said in a statement.
"Galileo is a project that only a united Europe can accomplish. A divided Europe can only endanger the success of the project."
A combined consortium of primarily French, German, Spanish, British and Italian industrial heavyweights are currently negotiating to build and deploy the system.
Companies involved in the consortium include European aerospace giant EADS, France's Thales and Alcatel, Britain's Inmarsat, Italy's Finmeccanica, and Spain's AENA and Hispasat.
German Transport Minister Manfred Stolpe told Reuters last week that Deutsche Telekom AG's information technology unit T-Systems, the German Aerospace Centre and Bavarian development bank LfA Foerderbank Bayern would join the group as a combined eighth member.
The eight parties would each have a 12.5 percent stake of the bidding consortium, he said.
Barrot urged all sides to cooperate with Van Miert.
Galileo is scheduled to go into service in 2008 and eventually will have 30 satellites for mostly civilian uses ranging from driver assistance to search and rescue help.
The 25-nation EU has enlisted international partners including China and Israel to help fund the project. The Commission estimates the development phase to cost 1.5 billion euros ($1.8 billion) and deployment to cost 2.1 billion euros.
