All of us depend on GPS for navigation: whether we’re using our smartphones, wearables or in-built vehicle satnav. But did you know that a GPS (GNSS) signal is only as powerful as a 45-watt lightbulb? This means that any obstruction can make it harder for a receiver to pick them up. Buildings can block them completely, just like the glow from a dim light can be blocked by a blackout curtain. Signals can also be impacted by tree cover -- with foliage they can still pass through, but the effect is like a thin curtain making a dim light even dimmer. Both high-rise buildings and foliage can cause disruptions to the GPS signal. GPS is one of the few sensors in the vehicle that provides an absolute location. As we move towards automated driving, the signal has to be accurate, reliable and secure for it to navigate safely, with confidence. However, this is easier said than done. The sensitivity of a receiver is a critical consideration for developers of Advanced Driver Assistance Systems (ADAS). 👉 This article outlines the challenges of signal sensitivity in the design of automated vehicles and outlines how OEMs can leverage our technology to extend hands-free driving into challenging environments. https://lnkd.in/ewCSzQvj #GNSS #ADAS #AutonomousDriving
