Inside the Double-Fast Update Rate: the Whys and Wherefores of Ultra-rapid GNSS Simulation

For testing PNT systems in a high-dynamics environment, such as rockets, guided munitions and even some UAVs, a realistic reproduction of that environment requires a lot of quick looks. A very great lot. The high speeds, acceleration and jerkiness of the platforms mean that solving simulation discrete models as frequently as possible becomes critical to ensure […]
