Satellite to Satellite Visibility [PDF]
The Open Astronomy Journal, 2012 In this paper, general analytical and computational technique for satellite-to-satellite visibility will be established. The developments are general in the sense that the visibility conditions can be used whatever the types of the satellite orbits may be. Numerical applications are also included.
