Design of the Angle-Resolving Electron Spectrometer Aboard the PRESET Mission

We present a design study for the Pitch REsolving Spectrometer for Electron Transport (PRESET) mission, a CubeSat that is aimed at measuring the pitch angle density spectrum in low-Earth orbit (LEO). While a few missions have measured the pitch angle density spectrum, all have provided low resolution within the loss cone. PRESET will be capable of measuring pitch angle density of electrons with a resolution of 10 degrees or better and an energy …
