BroadSim Defense From Orolia Talen-X

Affordable Software-Defined GNSS Simulator For Advanced NAVWAR Signal Simulation

You want to evaluate the operation and performance of SAASM and M-Code receivers in clear and threat environments, including those that may be subjected to jamming and spoofing attacks.

BroadSim Defense (powered by Skydel). BroadSim Defense supports high dynamics, advanced jamming, spoofing, and encrypted military codes. Powered by Skydel’s SDX Global Navigation Satellite System (GNSS) simulator engine, BroadSim Defense is able to simulate P-Code, P(Y)- Code, AES M-Code, and MNSA M-Code.

Why Choose BroadSim Defense?

BroadSim Defense is revolutionizing the GNSS industry because of its extraordinary flexibility, low cost and ability to achieve rapid development cycles. By leveraging Skydel’s 1000Hz SDX navigation engine and COTS radios, it can simulate encrypted and unencrypted GNSS signals at the same time, at a fraction of the cost of comparable simulators. BroadSim Defense is unique in that it takes advantage of state-of-the-art RF commercial off-the-shelf (COTS) hardware during processing and generates signal data using COTS graphics-processing units (GPU). Its ability to generate multifrequency encrypted codes on a COTS system maximizes scalability, value and reduces time to market.
