Rohde & Schwarz (R&S) and MILTON are taking drone-based radio-frequency (RF) intelligence to the next level with two new monitoring payloads set to debut at MILIPOL Paris 2025.
The MILTON Long-Range Observer (LRO) drone now carries the R&S EM200 signal analyzer and an omni-directional antenna, all run through the CEPTOR suite.
The setup delivers wide-area RF surveillance and long-range detection of communication signals, jammers, and other electromagnetic emissions.

A second payload equips the MILTON Keeper drone with the EM200 signal analyzer and the R&S ADD507 direction-finding antenna, also controlled by the CEPTOR.
This gives operators precise geolocation to pinpoint the source of suspicious or hostile transmissions in real time.
Together, these payloads are intended to provide defense forces with flexible, fast-deploying RF monitoring capabilities, without relying on larger, less agile aircraft.
Elevating RF Ops
The collaboration builds on previous work integrating electromagnetic warfare tech, boosting intelligence gathering and situational awareness on the battlefield.

By pairing MILTON’s agile drones with R&S’ CEPTOR suite, more spectrum-monitoring power is being pushed onto compact, autonomous platforms.
“We are proud to continue our collaboration with MILTON, pushing the boundaries of what’s possible in autonomous airborne systems,” said Stéphane Blanc, Managing Director, R&S France.
“These new deployments, leveraging the power of our R&S CEPTOR suite, demonstrate our shared commitment to innovation and providing defense forces with the tools they need to proactively address emerging threats.”
