Swarm, the fifth Earth Explorer mission approved in ESA's Living Planet Programme and launched on November 22, 2013, 1:02 pm (CET), consists of a constellation of three identical satellites in near-polar orbits between 400 and 550 km altitude.
Aim: The main objective of the Swarm mission is to provide the best ever survey of the geomagnetic field and its temporal evolution, and gain new insights to improve our knowledge of the Earth's interior and near-Earth's magnetic environment. Observations of the strength and direction of the magnetic field, the electric field and plasma densities and temperatures, navigational signals, and derived parameters enable novel research on the understanding of the various sources of the geomagnetic field.
GFZ has supported the mission development and scientific product definition, and is involved through several scientific and coordinating activities for its calibration and scientific exploitation.

Swarm is ESA's first constellation mission for Earth Observation (EO). This mission is operated by ESA's European Space Operations Centre (ESOC), in Germany, via the primary ground station in Kiruna, Sweden. This mission consists of the three identical Swarm satellites (A, B, and C), which were launched on 22 November 2013 into a near-polar orbit ...
