The HP GNSS Sensor Windows driver is a software package that enables communication between the operating system and the Global Navigation Satellite System (GNSS) hardware component in an HP laptop or desktop. GNSS is used for location-based services, such as GPS functionality, geolocation, and mapping, in devices that are equipped with a GNSS sensor. This sensor allows the device to track geographic location and altitude, which is especially useful in applications like navigation, location-based services, and other geospatial tasks.
