Spacecraft potential control aboard Equator-S as a test for Cluster-II [PDF]
Annales Geophysicae, 1999 The payload of Equator-S was complemented by the potential control device (PCD) to stabilise the electric potential of the spacecraft with respect to the ambient plasma. Low potentials are essential for accurate measurements of the thermal plasma. The

Simulation of the Cluster-Spacecraft Floating Probe Potential [PDF]
IEEE Transactions on Plasma Science, 2006 In this paper, a numerical model of the Cluster-spacecraft electric potential has been developed and validated. This model provides a good fit to the plasma density as a function of spacecraft chassis potential relative to a Langmuir probe as recorded ...

Statistical Survey of the Terrestrial Bow Shock Observed by the Cluster Spacecraft [PDF]
Journal of Geophysical Research: Space Physics, 2019 The terrestrial bow shock provides us with a unique opportunity to extensively investigate properties of collisionless shocks using in situ measurements under a wide range of upstream conditions.

Whistlers observed by the Cluster spacecraft outside the plasmasphere. [PDF]
Journal of Geophysical Research: Space Physics, 2005 [1] Lightning generated whistlers are ubiquitous within the plasmasphere at both high and low altitudes, and these waves propagate efficiently in both ducted and nonducted modes.

Active spacecraft potential control for Cluster – implementation and first results [PDF]
Annales Geophysicae, 2001 Electrostatic charging of a spacecraft modifies the distribution of electrons and ions before the particles enter the sensors mounted on the spacecraft body. The floating potential of magnetospheric satellites in sunlight very often reaches several

Anisotropic turbulent spectra in the terrestrial magnetosheath as seen by the cluster spacecraft. [PDF]
Physical Review Letters, 2006 Here we report the first three-dimensional spatial spectrum of the low frequency magnetic turbulence obtained from the four Cluster spacecraft in the terrestrial magnetosheath close to the magnetopause.

Polar and Cluster observations of a dayside inverted-V during conjunction [PDF]
Annales Geophysicae, 2007 We investigate particle and fields data during a conjunction of the Polar and Cluster spacecraft. This conjunction occurs near the dayside cusp boundary layer when a dayside inverted-V was observed in the particle data of both satellites.

An initial investigation of the long-term trends in the fluxgate magnetometer (FGM) calibration parameters on the four Cluster spacecraft [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2014 Over the course of more than 10 years in operation, the calibration parameters of the outboard fluxgate magnetometer (FGM) sensors on the four Cluster spacecraft are shown to be remarkably stable.

Detection of meteoroid hypervelocity impacts on the Cluster spacecraft: First results [PDF]
Journal of Geophysical Research: Space Physics, 2016 We present the first study of dust impact events on one of the Earth‐orbiting Cluster satellites. The events were identified in the measurements of the wide band data (WBD) instrument on board the satellite operating in monopole configuration. Since 2009

A statistical study of magnetospheric electron density using the Cluster spacecraft [PDF]
Journal of Geophysical Research: Space Physics, 2016 Observations from the WHISPER (Waves of High frequency and Sounder for Probing of Electron density by Relaxation) instrument on board Cluster, for the interval spanning 2001–2012, are utilized to determine an empirical model describing the total electron
