Reliable GNSS Positioning in Urban Areas: A Key Technical Challenge for Drones and Self-Driving Cars

Signal reception is one of the big technological challenges of the modern age. Today, it’s mostly thought of as a telecoms issue. If someone complains that their smartphone has ‘lost reception’, they’re most likely referring to a loss of cellular signal. And the chances are it’s because they’re in a rural location, far from any […]

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 […]
