The proposed TIWS Cubesat is instrumented to remotely sense waves in the upper mesosphere using nadir O2 Atmospheric (0-0) band airglow measurements and ionospheric structure with in-situ ion density measurements. The mesospheric airglow observations will provide a brightness perturbation measurement (I’/I) that is directly related to wave amplitudes. The ratio of the P to R branch within the band will provide a measure of the layer brightness rotational temperature, as well as wave amplitudes (T’/T), but phase shifted to the wave amplitude measured by I’/I. In addition to wave amplitudes, vertical wavelengths (λz) are deduced from the phase difference between I’/I and T’/T. Horizontal wavelengths (λx) are measured only when 2-D information is available such as near observatories, but global measurements of amplitude and λz, from phase, are independent of λx. TIWS will also be instrumented with a Retarding Potential Analyzer (RPA). The RPA will nominally be operated in a current mode, related to the ion density and density perturbations along the orbit. Additional modes will be designed for the RPA to periodically determine the ion composition and ion temperature, and to provide a burst mode for gathering high-resolution ion density fluctuation measurements in equatorial spread F. The bus for the 3-U satellite will be the Illinisat-2.
