Unmanned aerial systems have become the backbone of modern military operations, and the radios that link them to ground control, mission commanders, and coalition partners are now mission-critical subsystems in their own right.
As the military UAV radio market shifts from single-purpose, hardware-locked designs toward multi-band, software-defined radios (SDRs) capable of operating across the contested and congested spectrum, the burden on test and validation infrastructure has never been greater. Astronics’ ATS-6100 Radio Test Set (RTS) was engineered to meet that burden head-on—delivering benchtop-grade test capability in a rugged, handheld package built for the flight line, the depot, and the field.
At just under 13 pounds, battery-powered, and packed with 19+ instruments, the ATS-6100 RTS brings comprehensive radio test coverage to environments where stationary systems simply can’t go. That portability matters more than ever as UAV programs scale: with radios per platform increasing and multi-radio communication suites becoming standard, technicians need a tool that can validate command-and-control links, payload data links, and relay radios wherever the UAV is staged—not just in a lab.
Wideband coverage from 1 MHz to 1 GHz, extendable via software to 3 GHz or 6 GHz, means the ATS-6100 RTS supports the legacy VHF/UHF tactical radios still in service alongside the emerging L-, S-, and C-band systems driving next-generation UAV connectivity. It tests ground and airborne radios from virtually any OEM, addressing one of the sector’s most persistent pain points: interoperability across mixed fleets of legacy, allied, and next-generation platforms. As NATO STANAG compliance and cross-fleet interoperability become non-negotiable procurement criteria, a test set that isn’t locked to a single manufacturer’s ecosystem is a genuine strategic asset.
The ATS-6100 RTS’s measurement suite—VSWR, power, frequency error, modulation, and SINAD/distortion, backed by a built-in VNA and spectrum analyzer—gives technicians the diagnostic depth needed to validate radios against the anti-jam, anti-spoof, and link-resilience requirements now shaping UAV radio procurement. Critically, many of these tests can be performed over-the-air, without a direct radio connection—an essential capability for evaluating airborne links and antenna performance under conditions that mirror real contested-RF operations, rather than idealized bench setups.
For programs racing against multi-year certification timelines, the ATS-6100 RTS’s shared software interface with the benchtop ATS-3200 RTS—paired with optional Guided Test Scripts—means technicians can move fluidly between field and depot testing without retraining, shrinking qualification cycles and easing the SWaP and lifecycle-support burden that many UAV radio suppliers still struggle to address.
As UAV fleets grow more networked, more software-defined, and more essential to coalition operations, reliable, field-ready test capability isn’t a nice-to-have—it’s foundational to keeping those radios mission-ready. The ATS-6100 RTS delivers exactly that: precision testing engineered for wherever the mission takes it.
