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...]

How to Build a Reliable TDR from S-Parameters to Reduce EMI Worries
When Two TDRs Don’t Agree As modern high-speed designs push into multi-gigabit and higher data rates, EMI and EMC engineers rely on multiple signal integrity (SI) metrics to evaluate interconnect performance. Among these, time-domain reflectometry (TDR) remains one of the most direct methods for identifying controlled impedance and … [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...]
