Description
Summary:Many modern personal devices (cell phones, tablet computer, smart watches, etc.) contain embedded GNSS receivers capable of determining their position with a typical error of around 8-20 meters. Recent improvements to the software and hardware of these devices have given access to the raw GNSS data allowing developers the ability to manipulate and refine the computation of the position solution produced by the embedded GNSS receiver. This paper discusses the implementation of networked differential ground stations in an effort to reduce the error of a GNSS receiver on a mobile device and describe the improvement obtained.
