The project main steps
|
| The SWARM mission a constellation of three identical satellites to measure the Earth's magnetic field, was decided by ESA as an Opportunity mission as part of the Earth Explorer Program. The three satellites will be launched together in 2012. |

|
The scientific objective of the mission is to provide the best ever survey of the geomagnetic field and its temporal evolution, in order to gain new insights into the Earth system by improving our understanding of the Earth's interior and Sun-Earth connections.
The french contribution to this mission consists in the CNES supplying the absolute magnetometers (ASM: Absolute Scalar Magnetometer) which will equip the 3 satellites of the constellation, in addition IPGP will carry out the scientific validation of the data generated by the ASM. The magnetometers are developed by LETI, they are much more accurate than those from the ØRTED and CHAMP missions which preceeded SWARM.
