As GPS jamming and other forms of GNSS disruption become more widespread, researchers are advancing alternative navigation technologies that could provide positioning when satellite navigation is unreliable or unavailable. A recent report from The Economist examines two approaches gaining traction. One uses highly sensitive magnetometers to navigate against maps of variations … [Read more...]
Auterion Introduces Nemyx Vertical Launch System for Drones from Any Vendor
Auterion has introduced the Nemyx Vertical Launch System (Nemyx VLS), a modular launcher for drones from multiple manufacturers. It extends Nemyx, the Auterion swarm engine, from software into the hardware that puts drones in the air. The same launcher takes high-volume commercial drones, strike drones and interceptors. Inside each tube, drones are stacked vertically. An … [Read more...]
The Role of an EMC Engineer in Product Development
Coming out of college, whether it’s electrical, mechanical, software, or any other engineering discipline, a lot of young engineers picture themselves as Tony Stark building an Iron Man suit or as Mark Watney getting stuck on Mars and engineering his way back home to Earth as their future career. What many young engineers don’t quite understand is that engineers … [Read more...]
EagleNXT Tests eBee VISION UAS Anti-Jamming Technology in Contested RF Environment
EagleNXT recently tested its eBee VISION unmanned aircraft system under communications, navigation and radio-frequency conditions designed to simulate a contested electromagnetic environment. According to a company announcement, the testing took place September 13–18 at Camp Grayling Joint Maneuver Training Center in Michigan as part of a Denied, Disrupted, Intermittent and … [Read more...]
Frequency Interference Suspected After Drones Fail at South Korean Defense Demo
Frequency interference is being investigated as a possible factor after six of 17 drone demonstrations failed during South Korea’s 2026 Defense Drone Technology Exhibition. According to reporting by Lee Hyun-ho for Seoul Economic Daily, all 17 demonstrations had succeeded during rehearsal the previous day. Military officials reportedly suspect that increased RF activity … [Read more...]
Column | Drones: Flying Vegabonds of Potential EMC Non-Compliance
A few weeks ago, I was pulling my bins in from the curb after garbage pick-up day, and I heard a faint whirring coming from somewhere in my neighborhood. At first, I thought it was the Pennsylvania Turnpike, but the tone was different than usual. My son told me to look up. The whirring was emanating from an object in the sky with small, blinking, red and blue LEDs. A … [Read more...]
EMC for Missiles
Introduction Missile platforms operate in some of the most extreme electromagnetic (EM) environments encountered by aerospace systems. The combination of high‑power radar, directed‑energy weapons, lightning, electromagnetic pulse (EMP), and electro‑static discharge (ESD) creates a complex threat landscape that can compromise functionality, safety, and survivability. Emphasis … [Read more...]
What’s New in MIL-STD-461H
The long-awaited revision to MIL-STD-461H was released on April 17, 2026. This revision formally supersedes MIL-STD-461G, issued on December 11, 2015. However, anyone involved in the MIL-STD-461 compliance arena understands that adoption through the procurement cycle will take time. There is no reason to discard those copies of revisions A through G anytime soon. Although I … [Read more...]
