Merge/Space (M/S) is a testbed designed to simulate multiple-agent security scenarios in satellite networks. By combining orbital data generated by a simulator such as STK with a synchronized set of images, M/S can accurately simulate bandwidth and connectivity constraints between ground stations and vehicles, enabling analyses of DoS attacks, scanning, malware infiltration and other analyses. We discuss the development of the testbed, the sample datasets included for release, and demonstrate the impact of various simulations.
