Advertising has recently taken on a new arena, creating signs in space that would be visible from the ground. However, known solutions require large satellites and expensive (heavy) deployment mechanisms and resources. The presented method introduces the usage of nano-satellites for forming the signs. This would enable easy display of changing signs over different territories and time windows. Additionally, this method takes into account the constraints on available energy as well as possibilities of exploiting sunlight for the sign formation. This solution can also be applied to the display of disaster warnings or during major national celebrations.
