MUOS will augment and replace the legacy UltraHighFrequency (UHF) Follow-On system (UFO) providing assured communications, including simultaneous voice, video and data, for mobile warfighters.
The system uses the emitter to send ultrahighfrequency signals after coding with signal coder and the secondary superheterodyne mixing receiver to accept the moving target signals.
