This paper presents the research that is being conducted with the hardware-in-the-loop simulation testbed laying at the Nano Satellite Lab at the Kiruna Space Campus of Luleå University of Technology. Particularly, a brief introduction to the frictionless platform and both robot manipulators that comprise such a testbed is given. Additionally, this paper summarizes the simulations that are currently performed on the testbed. Finally, the paper also discusses some future activities that are planned to be conducted to improve the way systems and components of small satellites are currently validated.
