in June 2009. The instrument is a 1 meter class balloon-borne telescope equipped with a
vacuum-ultraviolet integral field spectrograph intended to detect emission from the inter-
galactic medium at redshifts 0.3< z< 1.0. The scientific goals and the challenging
environment place strict constraints on the pointing and tracking systems of the gondola. In
this manuscript we briefly review our pointing requirements, discuss the methods and …
