Nov 1, 2008 · In this paper, recent improvements in the modeling capabilities of the Spacecraft Plasma Interaction Software (SPIS) code are presented. New developments still in progress are also reported.

Sep 1, 2015 · Spacecraft charging in GEO particularly concerns dielectric surfaces that may charge to significant voltages relative to spacecraft ground because of the space environment. Testing materials helps...

The plasma environment, namely its density and energy, is the crucial parameter for spacecraft charging analysis. We statistically analyzed the environmental condition in PEO using the data of auroral electrons and thermal ions measured by DMSP (Defense Meteorological Satellite Program) satellites.

lasma contactor effect of a plasma thruster is essential to correctly estimate and model its electrostatic impact on the spacecraft charging. But we will see that the generally accepted hypothesis of assumption is not adapted to take account of the plasma conta

The first one was an implicit circuit solver with an automatic determination of time steps. The implemented Newton-type algorithm makes use of a predictor for the plasma current variations when surface potentials change. The second major development was a …

Two major improvements were brought to SPIS code to answer these needs. The first one was an implicit circuit solver with an automatic determination of time steps. The implemented Newton- type...

Abstract: Modeling the coupling between an all-electric spacecraft, its plasma plume and its environment is a long-standing challenge because of the numerous physical processes that are involved and the need of modeling all of them accurately to obtain a …

Plasma ground tests introduced some kind of facilities to study spacecraft interaction with ionospheric plasmas at NRIAG. In this paper, the description of design and performance of our ground based simulation plasma in low earth orbit (LEO) are presented.

Following a survey of current sources that contribute to spacecraft charging at LEO, we will discuss the principal current source from the ionospheric plasma.
