Configurable according to your requirements, the Portable Simulator enables high precision testing that can move from location to location. Whether in the lab or in the field, and whether conducted or radiated, the Portable Simulator delivers signals from GPS, Galileo, GLONASS, BeiDou and QZSS for powerful and flexible GNSS testing. In addition, the ability to closely synchronise to live sky signals offers the capability to conduct powerful in-field spoofing testing.
While laboratory testing offers the greatest possible control over the environment, testing of the fully integrated product in its final form factor is often carried out in a live sky environment. The Portable Simulator brings the control and integrity needed to this environment, enabling powerful spoofing testing using real-world signals. The capability to synchronise to live sky signals make it the perfect tool to facilitate advanced testing — from trajectory to navigation data spoofing.
Due to high power requirements, form factor and weight, most lab-based test equipment cannot easily be moved. However, portable solutions often lack the required precision and realism, as well as a truly flexible and feature-rich control software platform. The portable simulator enables users to perform powerful and reliable testing between different locations without compromising on performance or useability.
