For the last couple of Months we have been busy preparing a demonstrator that shows the effect of Earths albedo on the attitude error of analogue Sunsensors. In the future this setup is also expected to show the lack of albedo sensitivity for our digital Sunsensor. Demonstrating at theESA GNC & ICATT Conferencein two weeks will be the introduction to the public of this illustrative setup partially designed by students ofLeidse instrumentmakers Schooland finished byJelle van der ploeg,Suman KasaniandGruia Pascanu
