Get tips on efficiently improving the performance of phased array antenna designs. Dr. Wilfredo Rivas-Torres references real-world projects as he examines the RF characterization of a phased array receiver, including: Statistical and element failure analysis Active impedance Beamforming IC (BFIC) modeling Design trade-offs of performance versus cost, showcasing channel impairment…

Stay up late sometime when the moon is past full and look at the large dark oval near its western edge. Renaissance astronomers called it the Ocean of Storms, Oceanus Procellarum, not knowing it was a hundred times drier than the most arid desert on Earth. But there is water…

The Jet Propulsion Laboratory’s Ingenuity helicopter is preparing for the 50th flight of its five-flight mission to Mars. Flight 49, which took place last weekend, was its fastest and highest yet—the little helicopter flew 282 meters at an altitude of 16 meters, reaching a top speed of 6.50 meters per…

A rocket carrying CubeSats launched into Earth orbit two years ago, on 22 March 2021. Two of those CubeSats represented competing approaches to bringing the Internet of Things (IoT) to space. One, operated by Lacuna Space, uses a protocol called LoRaWAN, a long-range, low-power protocol owned by Semtech. The other,…

Space is hard. Every time a rocket crashes or a probe goes silent, someone invokes the mantra that it’s hard to reach for the stars. Rockets are complicated machines, often with thousands of parts that can doom a mission if just one fails. Relativity Space, a California-based startup, is trying…

With satellite competition growing exponentially, advanced virtual prototyping and design techniques are needed to keep pace. Join our webinar to hear from Dr. Wilfredo Rivas-Torres of Keysight Technologies. He will cover 3D/conformal phased array analysis and dynamic mission performance simulations. Learn how to: Analyze a SatCom link budget Integrate dynamic…

On a gin-clear December day, I’m sitting under the plexiglass bubble of a radically new kind of aircraft. It’s a little past noon at the Byron Airport in northern California; in the distance, a jagged line of wind turbines atop rolling hills marks the Altamont Pass, blades spinning lazily. Above…

The 19-seater Dornier 228 propeller plane that took off into the cold blue January sky looked ordinary at first glance. Spinning its left propeller, however, was a 2-megawatt electric motor powered by two hydrogen fuel cells—the right side ran on a standard kerosene engine—making it the largest aircraft flown on…

The typical positional accuracy provided by standalone GNSS is 3-10 meters, which is suitable for automotive applications such as navigation and emergency call. With the emergence of high precision GNSS, able to mitigate the influence of errors, sub-decimeter positional accuracy is possible and it becomes usable for more advanced applications…
