Ultraviolet Tomography from CubeSat-based Sensors

The Triple Tiny Ionospheric Photometer (Tri-TIP) is a compact, ultraviolet (UV) sensor that has been developed as part of the Coordinated Ionospheric Reconstruction Cubesat Experiment (CIRCE). Tri-TIP will measure OI 135.6 nm emissions in the nighttime ionosphere that will be tomo-graphically inverted to determined vertical profiles of electron density in the orbit plane. The Volume Emission Rate Tomography (VERT) method has previously been validated using data from a limb scanning UV spectrometer. The current work will assess the viability of the VERT method when applied to fixed, overlapping view angles from a CubeSat platform.
