Achieving Maximum Realism in GNSS Spoofing Testing

The aim of GNSS receiver testing is to understand and optimize how the device will perform in the real world. But that immediately creates a quandary for test teams. Rigorous testing requires the test environment to be repeatable and controllable, but the real-world environment is rich and dynamic. So how can testers bring realism into […]

6 Ways the Design and Build of an RF Simulator Can Affect the Realism of GNSS Testing

In order to bring as much testing into the lab as possible, a GNSS test environment should be able to reflect the real world as closely as possible. To achieve that realism, test teams rely on radio frequency (RF) simulators to generate faithful replicas of real-world GNSS signal environments. But how “real” is the environment […]

BVLOS vs BLOS for UAS and Drone Operations: What’s the Difference?

The world of unmanned aircraft systems (UAS, or drones) is evolving fast, bringing a whole new set of acronyms for drone operators and aviation regulators to get to grips with. One of the most important concepts in drone operation is “line of sight” (LOS). Many of the current rules hinge on whether a drone is […]
