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 tomographically 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.
