R&S®UMS175 Compact Radiomonitoring System At a glance The R&S®UMS175 combines state-of-the-art receiver technology with flexible communications capabilities and a control PC in a compact allweather cabinet. The result is an extremely powerful and versatile outdoor system for radiomonitoring and emitter location based on measuring the time difference of arrival (TDOA). As a receiver within a TDOA network, it delivers I/Q samples for high-precision location missions. High system sensitivity and an integrated preselection filter make the system ideal for deployment in difficult signaling...

System configuration The optional all-weather cabinet (R&S®UMS12-B1) protects the radiomonitoring system against external mechanical impacts, expanding the range of applications for outdoor deployment. The R&S®UMS175 base unit includes a receiver, a control PC, router, LAN and a power supply. All components are integrated in the inner enclosure. Two antenna inputs are connected to the receiver via a switch. The integrated heating system makes it possible to operate the R&S®UMS175 outdoors even when temperatures are very low. The control PC (with a Windows 7 Embedded operating system), the...

Operation Several software solutions are available for controlling the R&S®UMS175. The receiver control software is included in the R&S®UMS175 base unit. If the R&S®UMS175 is used as a local or remote sensor in COMINT/CESM applications, the R&S®RAMON system software is recommended for most efficient operation. The R&S®ARGUS standard software for ITU-compliant monitoring offers impressive capabilities for spectrum monitoring with a wide range of functions and user-friendly operation. Furthermore, open, well-documented interfaces make it possible to develop custom software applications....

Example: transmitter location via TDOA Time difference of arrival (TDOA) exploits instantaneous snapshots of a transmitter signal (I/Q data) simultaneously recorded by several TDOA receivers. Since the ­ eceivers r are located at different distances from the transmitter, they receive the same signal at slightly different times. The transmitter’s position is then determined by correlating the individual I/Q data. The R&S®UMS175 serves as a receiver within a TDOA network. The integrated GPS receiver provides timestamps for the I/Q data with accuracy in the nanosecond range. That data is send...
