统一S波段测控系统(英語:Unified S-Band TT&C System,简称USB)是现代空间技术的重要组成部分,它是在连续波定位、遥控、遥测和通信等技术基础上发展起来的综合性多功能测控系统。 The Unified S-band (USB) system is a tracking and communication system developed for the Apollo program by NASA and the Jet Propulsion Laboratory (JPL). It operated in the S band portion of the microwave spectrum, unifying voice communications, television, telemetry, command, tracking and ranging into a single system to save size and weight and simplify operations. The USB ground network was managed by the Goddard Space Flight Center (GSFC). Commercial contractors included Collins Radio, Blaw-Knox, Motorola and .
