Say So Long to FPGAs

BroadSim is revolutionizing the GNSS industry because of its extraordinary flexibility, low cost, upgradability, and rapid development cycles. Leveraging the Skydel navigation engine and commercial-off-the-shelf (COTS) Software-Defined Radios (SDRs), simulation of GNSS signals can be achieved at a fraction the cost of today’s industry standards. The ability to generate military and multi-constellation signals on COTS hardware maximizes scalability, value, and time to market.

Advanced Jamming and Spoofing

Add ground and space-based emitters to your scenario, generate an unlimited number of jamming signals on 1 RF output, and simulate flight profiles where interference power levels at the UUT dynamically change depending on the scenario motion.

Simulate multiple spoofers simultaneously. Each spoofer can generate any GNSS signal and has an independent trajectory and antenna pattern. Signal dynamics between each spoofer and receiver antenna are automatically determined so no time is wasted.
