BroadSim SPACE From Orolia Talen-X

Affordable Software-Defined GNSS Simulator For Orbital Trajectories and Space Models

You want to launch a satellite into space and test how it’s going to perform.

BroadSim SPACE (powered by Skydel). Supports ground-based LEO, MEO, GEO and beyond receiver trajectories. BroadSim SPACE carefully simulates the Global Navigation Satellite System (GNSS) constellations, analyzing situations that can only occur in space, such as a vehicle out of the GNSS satellite antenna’s primary lobe. BroadSim SPACE simulates multiple constellations, including Galileo and GPS.

Why Choose BroadSim SPACE?

BroadSim SPACE 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 multi-frequency GNSS signals at the same time, at a fraction of the cost of comparable simulators. BroadSim SPACE 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 unites (GPU). Its ability to generate multi-frequency and multi-constellation codes on a COTS system maximizes scalability, value and reduces time to market.
