SatCAT is a tool that allows you to create a timeline of the current and historical charging levels of a satellite on orbit. The tool is configurable so that you can generate and view internal charging levels for your chosen satellites and design paramaters such as shielding thickness and materials. The tool also allows you to add anomaly times so you can compare charging levels directly with on-orbit anomalies and identify corelations.

Recent/Current Charging Conditions at GEO
The plot shows the recent history of accumulated charge in Kapton materials at GEO orbit for different shielding thicknesses.
(Red denotes charging levels above the 97%, yellow above the 92% and green is below that since 2016).
