The Extreme Energy Events Project is an experiment devoted to the study of the Extensive Atmospheric Showers (EAS) which consists of a network of Multigap Resistive Plate Chambers (MRPCs) muon telescopes distributed over a very large area ∼3times105km2. It requires a precise time synchronization to correlate the information collected from each single detector. The data acquisition system of each telescope is equipped with a trigger unit and a GPS receiver to perform precision timing of events. The Global Positioning System (GPS) unit provides the one pulse per second signal (1PPS) which is used to create a timestamp in UTC time. A novel VME trigger unit for the EEE telescopes was developed, including an embedded GPS engine for timing application. The trigger/GPS unit is presented, including some preliminary measurements of its time resolution. •The VME trigger unit includes an engine GPS to create the timestamp in UTC time.•The absolute time of an event is built by adding both the TDCs and the GPS data.•GPS unit provides the one pulse per second signal (1PPS) to synchronize the TDCs.•The time resolution measured for the 1PPS is less then ∼5 ns.
