| | Earth Observation - Mission accomplished for GOCE and its ONERA accelerometers... This equipment is based on the ultra sensitive measurement capability of six accelerometers (or g-meters) designed and developed by ONERA.... Due to their extreme accuracy, these accelerometers will provide a Geoid representation with unequalled spatial resolution for oceanographers, seismologists and geophysicists, allowing more accurate knowledge of ocean circulation dynamics, or a better understanding of the processes at work in terrestrial crust movements in relation to earthquakes, for example.... |
