GLUV pathfinder mission

GLUV is a balloon-based near UV survey telescope under development. The primary objective of GLUV is high-cadence observations of transient events such as early UV observations of supernova. The ozone layer absorbs a considerable amount of UV radiation, so it is important for a UV balloon telescope to achieve flight altitude above the ozone layer. The ozone layer density varies with respect to latitude, altitude and season. The structure and behaviour of ozone distribution is an important factor to be studied to account for astronomical ultraviolet observations. GLUV pathfinder is a spectrometer based system to identify the sky background at intended flight altitudes and atmosphere transmission GLUV will experience. In this presentation, we will present the design and development of the GLUV pathfinder system.
