The European Commission (EC) is taking steps towards the implementation of a Galileo Timing Service. The Service is now formally part of the mission of Galileo Second Generation, and it puts emphasis to serve critical infrastructures.

To implement a proper Service implies to put all the necessary elements in place to be able to meet the defined level of performance. In order to ensure the correct processing of the Service signals and a minimum level of performance of the user receiver, corresponding standards are needed. Therefore, a fundamental element in the Galileo Timing Service concept is the standardisation of Galileo Timing Receivers.

The STARLITE project (Preparation of Standards for Galileo Timing Receivers) funded by EC is the first international initiative to develop Standards for GNSS timing receivers.

The target users for the standard are all Galileo Timing users, with special focus on critical infrastructures within Telecommunications, Finance and Energy Sectors.

The standard leverages on the specificities of the Galileo Timing Service. This will become fundamental in order to ensure the end-to-end performance for those users operating a receiver compliant with the standard. At the same time, the Standard allows the use of other systems to further enhance the performance.

The project helped to establish a formal Working Group (WG9) for the development of the Standard under CEN/CENELEC JTC5.

The aim of this paper is to provide a summary of the main outcomes of the activities developed in the frame of STARLITE project and WG9, in particular, the Galileo Timing Receiver functional and performance requirements, the associated Tests and the Guidelines for Installation and Maintenance of the equipment.
