Minimize What is Swarm?
Web Content Image

Swarm is the fifth Earth Explorer mission approved in ESA's Living Planet Programme, and was successfully launched on 22 November 2013.

The objective of the Swarm mission is to provide the best-ever survey of the geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of 3 identical satellites carrying sophisticated magnetometers and electric field instruments.

29 October 2015

The first set of Swarm Level 2 magnetic field products is complete and available for download. The set is comprised of models for the core field, lithospheric field, mantle conductivity, and external current systems in the ionosphere and magnetosphere.

New GPSR settings on Swarm A and B satellites

29 October 2015

The following GPSR optimised settings were uplinked to Swarm A on 8 October 2015 at 12:41 UTC and on Swarm B on 10 October 2015 at 12:11 UTC:

  • The bandwidth of the L1-carrier loop was increased by 50%
  • The bandwidth of the L2-carrier and P(Y)-code loops was increased by 100%
  • The fast reacquisition of the L1-carrier tracking was enabled by increasing the retry counter from zero to five
  • The number of tracked GPS satellites required by the onboard Kalman filter for calculating a valid navigation solution was reduced from three to one

Magnetic complexity begins to untangle

22 June 2015

After a year in orbit, the three Swarm satellites have provided a first glimpse inside Earth and started to shed new light on the dynamics of the upper atmosphere - all the way from the ionosphere about 100 km above, through to the outer reaches of our protective magnetic shield.
