Abstract

In order to model the fluctuations of the order of 5 km in the locator tangent height due to seasonal-latitudinal variations in stratospheric temperature, for improved accuracy in attitude determination from horizon sensors, a study was carried out on the dependence of 50% and 66% locator tangent height on the slope of the horizon radiance profile. A monotonic, second-order relationship was observed between the 66% locator tangent height and the slope of the horizon radiance profile.
