Two onboard atomic clock technologies have been developed for the Galileo system, one based on vapor cell rubidium technology (RAFS: Rubidium Atomic Frequency Standard) and one based on passive hydrogen maser (PHM) technology. In the years 2004-2005, both technologies have successfully passed a full qualification campaign (including shock, vibration, thermal vacuum, ...) aimed at verifying their performance in a Galileo-like environment. In the year 2005, six RAFS and two PHM ...
In preparation for the development of the Galileo system, the European Space Agency (ESA) launched in 2002 the development of an experimental ground segment (Galileo System Test Bed Version 1). Within the GSTB-V1 project, tests of Galileo algorithms were conducted processing GPS global data at the Ground Processing Center (GPC) located at ESA/ESTEC in The Netherlands. In December 2005 and then in April 2008, two experimental Galileo satellites called GIOVE-A ...
Since 1999 different timing activities at the INRiM (formerly IEN G. Ferraris) are devoted to the development of the European Satellite Navigation System Galileo, in collaboration with European space industries and the European Space Agency (ESA). Currently four main projects are in progress. In early 2006, an experimental phase called Galileo System Test Bed V2 (GSTB V2) or GIOVE Mission has been launched, supported by ESA, and INRiM takes part ...
