Willem Jordaan

Background

I am currently a lecturer in the Electric and Electronic Engineering Department, Stellenbosch University, South Africa. I obtained my PhD at Stellenbosch University in 2015. My dissertation mainly focused on the deployment and control of solar sailing satellites. During and since my post-graduate studies I have been involved in a number of satellite missions and contributed in the development of a variety of satellite hardware mainly focused on attitude control.
