The Precise Timing Facility (PTF) is an element of the Galileo Ground Mission Segment (GMS) and is responsible for maintaining and distributing the Galileo System Time (GST). The PTF is based on a set of Caesium clocks and Active Hydrogen Maser clocks, the combination of which should be able to provide the required precision and stability of the GST. As the PTF is a critical element within the GMS, diversity is applied in that two PTFs are made by two different companies. The subject of this paper is the PTF that is being developed by Kayser-Threde. To perform the Assembly, Integration and Verification (AIV) activities of the PTF, a dedicated test platform, PTF-AIVP, is developed by the National Aerospace Laboratory, NLR (the Netherlands) and the Nederlands Meetinstituut (NMi). The PTF-AIVP will be used to measure and analyse the (physical) output of the PTF, so that the stringent precision and stability requirements can be verified. Furthermore, it will simulate other Elements in the GMS that are connected to the PTF.
