Spacecraft exposed to space environments can experience harmful charging effects that manifest as damage to onboard electronics or interference with scientific measurements.

The Eidel Floating Potential Probe (FPP) is specifically designed to monitor a spacecraft's electrical potential relative to the surrounding plasma. Initially developed by the University of Oslo (UiO) and delivered in cooperation with Eidel, this instrument provides an essential safety layer for satellites operating in challenging space environments where traditional sensors may be too large or slow.
