Tester Simulates Crowded GNSS Signal Environments

Our crowded skies are filled with satellite signals that must be tested. To serve that purpose, Safran Federal Systems launched its BroadSim Genesis at the Institute of Navigation’s Joint Navigation Conference (ION JNC 2025) in Cincinnati, Ohio.

Developed for Global Navigation Satellite System (GNSS) simulation and Naval Information Warfare Systems Command (NAVWAR) testing of satellites, BroadSim Genesis supports generation of as many as 2,000 signals, to duplicate signal environments often typical of low-Earth-orbit (LEO) and medium-Earth-orbit (MEO) satellite constellations.

BroadSim Genesis (see image above) is well-suited for testing multiple-antenna and multiple-aircraft settings, including with jamming signals and other signal threats to satcom operation. The flexible system features an intuitive front panel that has N-type connectors for field-ready use.

Trevor Dougherty, vice-president of sales at Safran Federal Systems, said, “BroadSim Genesis is built for operators who demand flexibility, fidelity, and performance in their GNSS simulation tools. Whether validating mission equipment, training for NAVWAR scenarios, or assessing new PNT architectures, BroadSim Genesis gives defense users the edge they need.”
