ABSTRACT: A major development eort in the design of the Mobile User Objective System (MUOS) is the waveform used in software defined radios (SDR) to provide terminal and manpack UHF communication radios. Due to the complexity of using Spectrally Adaptive Wideband Code Division Multiple Access (SA-WCDMA) in the MUOS environment, Satellite Link Emulator test systems were required to aid in the MUOS waveform development eort. This article will give an overview of the architectural implementation of MUOS, its current status and an update of the associated satellite RF link emulator test equipment.
