Feedback form is now closed.
Over the past decade and owing largely to the smartphone revolution, GNSS (e.g. GPS) receivers have become ubiquitous with the number of devices in use estimated to surpass that of the world population within a couple of years.

So far GNSS receivers have lacked a representation in the Linux device model and have instead been handled entirely in user space. With the introduction of the serial-device bus, it has now become possible to add a higher-level abstraction and to utilise the kernel's infrastructure to provide better power management and simplified device detection.
