Minimize What is Swarm?

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.

New GPSR settings on Swarm A and C satellites

19 August 2016

Previous GPSR setting optimisation revealed that a wider L2 carrier loop bandwidth increased the robustness of the L2 carrier phase tracking. This is particularly evident in two bands parallel to the geomagnetic equator and in the regions around the geomagnetic poles, where phase residuals from precise orbit determination showed a significantly lower RMS.

Swarm L1B and L2 Cat-2 data regenerated for 02 and 03 April 2016

20 July 2016

An anomalous variation in the Inter Boresight Angle (IBA) for Camera Head Unit (CHU) pairs A-C and B-C has been observed for Swarm A during approximately 6 hours between 02 and 03 April 2016. Consequently the Swarm L1B and L2 Cat-2 data have been regenerated.

Swarm ASM-VFM residual dataset updated and extended

08 July 2016

With reference to the news published on 22 December 2015 we inform the users that the ASM-VFM Residual dataset produced for the investigations of the scalar residuals between the readings of the scalar magnetometer (ASM) and the vector magnetometer (VFM) have been updated to version 0408 for the period from the beginning of mission to 17 July 2015 and extended until 30 June 2016 for all Swarm spacecraft.

Seven ESA satellites team up to explore Earth's magnetic field

01 July 2015

For the first time ever, two of ESA's flagship space missions - Cluster and Swarm - have joined forces to simultaneously measure the properties of Earth's magnetic field at two different altitudes.
