Galileo Second Generation Satellites Batch 1 are designed to embark units (PMU) in charge of monitoring the low energy particles (ion and electron plasma). The Galileo PMU will be used to monitor the plasma environment during the entire mission and at Galileo orbits (MEO: 23 222 km altitude). The Galileo PMU will measure the effects of charged particles (electrons and ions) with non-relativistic energies (0,01-40 keV/q) which do not penetrate deep into satellite materials but cause surface charging. The PMU flight models (FM) will have to be designed to cope with the Medium Earth Orbit (MEO) environment and with an operational lifetime of 15 years. The activity covers the following deliverables: 6x PMU FM and 2x PMU engineering models (EM). An option is included for the delivery of 4x recurring PMU FM.
