Integrating Spirent GNSS Simulators with NI LabVIEW

In a co-simulation testing and R&D environment, integration of the equipment and interoperability of the systems involved is vital. To facilitate both elements, Spirent GNSS simulators provide an open, feature-rich API that enables users to remotely configure and control the simulator from an external computer. This API, SimREMOTE, enables Spirent to provide customers open interface […]

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 […]
