Abstract
GEO satellites and other space objects are studied in daylight, twilight and at night using IR cameras in clusters of no more than three with programs for pointing the instruments at known locations of the GEO objects and satellites and receiving weak near IR signals. Detection instruments have minimal optical surfaces and simple optical paths directing IR through Kshort and combined Kshort and H near IR band filters in cryogenic assemblies. Large focal ratios and large apertures reduce the effect of sky brightness, lower noise and improve the target signal, increasing the noise to signal ratio. Sky background noise is reduced by co-adding hundreds of pixels, allowing for the faint IR signal integration of one second or more. Results are read after integration.
