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 […]

How to Bring Realism into Your GNSS Testing with RF Record & Playback

A record & playback system (RPS) is a key element of the professional GNSS tester’s toolbox. These portable devices allow engineers to make digital recordings of the real-world RF environment and replay them to test the performance of GNSS receivers in real conditions. Unlike the real world, this replay facility allows conditions to be repeated […]

Alternative RF PNT & Spirent’s New Alt PNT Simulator

In a long history of navigation systems, GNSS is a relatively recent entry into the field.  Despite its newness, it is prevalent in nearly all industries.  The ability to provide instantaneous data with high accuracy and simplified operation for the end user has made GNSS a must have. Despite the pervasiveness and impact to everyday […]
