9 October 2015 Slitless spectroscopy of geosynchronous satellites
Author Affiliations +
A preliminary investigation into the use of slitless spectroscopy for characterization of geosynchronous satellites is described. A 100  line/mm diffraction grating is used as the dispersing device, and the spectral data obtained are compared to a model with good results. A method used to collect and calibrate slitless spectral observations accounting for pixel to wavelength conversion, pixel response as a function of wavelength, and solar features is presented. Observations of several geosynchronous satellites throughout a night reveal reflectance with noticeable and different profiles indicating that slitless spectroscopy offers the potential for another modality for identifying and discriminating satellites.
