LocusUSA is an engineering and software development company in West Melbourne on the Space Coast of Florida since 2001. It is a leader in radio frequency capture for radio analysis and location. The ability to capture and analyze the actual waveform of a radio transmission led to the development of DiagnostX, a patented system that can measure the alignment and operating characteristics of a radio, long-range over-the-air in real-time without user intervention.

LocusUSA supports government customers across the United States and Canada on the local, state and federal levels with this first-of-its-kind, proactive tool, ensuring the optimal performance of a radio system.
