has gloss | eng: Demeter (Detection of Electromagnetic Emissions Transmitted from Earthquake Regions) is a CNES micro-satellite, launched in 2004 with a 2-year planned lifetime, for developing earthquake prediction. The satellite measures ionospheric disturbances such as ion density and extremely low-frequency (ELF) changes in the Earth's magnetic field. The satellite is equipped with a segmented Langmuir probe that acts as a directional plasma-ion detector. The probe is divided into 7 discs on a spherically-tipped rod, with the rod also a probe. When combined, the discs act as a directional ion sensor. |
