Cusp observations during a sequence of fast IMF B_Z reversals [PDF]

Annales Geophysicae, 2009
In recent years, a large number of papers have reported the response of the cusp to solar wind variations under conditions of northward or southward Interplanetary Magnetic Field (IMF) Z-component (BZ).

ECLAT Cluster Spacecraft Magnetotail Plasma Region Identifications (2001–2009)

, 2014
The European Space Agency’s four-spacecraft Cluster mission has been observing the Earth’s dynamical magnetotail region since early 2001. The magnetotail, and in particular the hot trapped plasma sheet, is a critical region in the coupled Sun-Earth ...

The Cluster Magnetic Field Investigation: overview of in-flight performance and initial results [PDF]

Annales Geophysicae, 2001
The accurate measurement of the magnetic field along the orbits of the four Cluster spacecraft is a primary objective of the mission. The magnetic field is a key constituent of the plasma in and around the magnetosphere, and it plays an active role

Spacecraft potential control for Double Star [PDF]

Annales Geophysicae, 2005
The spacecraft potential of Double Star TC-1 is positive in large parts of the orbits due to the photo-effect from solar EUV irradiation. These positive potentials typically disturb low energy plasma measurements on board. The potential can be reduced,

Modulation of NTC frequencies by Pc5 ULF pulsations : experimental test of the generation mechanism and magnetoseismology of the emitting surface [PDF]

, 2009
Nonthermal continuum (NTC) radiation is believed to be emitted by the conversion of an electrostatic wave into an electromagnetic one, which takes place at the Earth's magnetic equator.

Long term and safe relative orbit design for heterogeneous spacecraft clusters

Advances in Space Research, 2021
Abstract The problem of obtaining long term relative orbit configurations for spacecraft clusters with realistic operational considerations such as safety, station keeping and inter-spacecraft distances is addressed. Two different approaches are developed for station keeping and safety objectives. In the first approach, relative orbit configurations,

Spatial scales of the magnetic ramp at the Venusian bow shock [PDF]

Annales Geophysicae, 2011
Typically multi-spacecraft missions are ideally suited to the study of shock spatial scales due to the separation of temporal and spatial variations. These missions are not possible at all locations and therefore in-situ multi-spacecraft measurements ...
