ABSTRACT: At SATELLITE 2025, a Maury Microwave demonstration showcases how the ACE9000 Advanced Channel Emulator can simulate multipath impairments on a communications link, specifically between a lunar rover inside a Moon crater and a terrestrial ground station, with a MEO/GEO satellite acting as a relay. To start, a vector signal generator (VSG) generates a narrowband communications signal, which is fed into the ACE9000. The emulator then simulates realistic multipath effects, where the signal interacts and reflects off the edges of the Moon crater, creating several paths for the signal to travel. After the impaired signal is processed through a vector signal analyzer (VSA), a monitor displays a multipath signal spectrum to visualize the impact of multipath propagation on signal quality.
