Freescale offers solutions for designing portable navigation devices
Since GPS has entered the civilian sector from military use, the application coverage of portable navigation devices (PNDs) has continued to expand. From smartphones to in-vehicle infotainment systems, this device is almost ubiquitous. Today, with the addition of China's Beidou satellite, China's navigation system has entered a more accurate, practical and efficient stage. At the same time, the function of the navigation system is no longer limited to the direction of guidance, but also provides users with enhanced and improved functions. Freescale offers a full range of products for designing portable navigation devices, including application processors, proximity sensors, accelerometers and analog circuits. Its flexible solutions help engineers develop innovative navigation devices with a variety of functions...
