ABSTRACT: At SATELLITE 2025, Maury Microwave will demonstrate the leading-edge capabilities of its non-terrestrial RF channel emulation solution – the ACE9000 Advanced Channel Emulator – by effectively and reliably emulating complex satellite communications links in real time. By importing two-line element (TLE) data, which contains a satellite’s orbital parameters for any given point in time, the ACE9000 will simulate multi-orbit signal impairments, such as path loss, delay, and Doppler, based on actual satellite behavior.
