OpenPosLib: A Library to Achieve Centimetric Geo-Spatial Positioning on a Budget

Positioning systems can be found everywhere, from the navigation system of a car to the smart watch that tracks the running performances of its wearer. With the generalization of positioning systems, new use cases have begun to emerge that require or could benefit from increased accuracy. While the technology has been detailed in the literature for several years, the deployment of positioning techniques at the centimeter level has proved challenging. In this paper we propose OpenPosLib, an open source library that aims to fill the gap between all the components needed to achieve a centimetric accuracy and the user-facing application. Our objective is to remove most of the complexity needed to obtain centimetric accuracy from the developer so as to enable end-users to reap the benefits of more applications that leverage centimetric accuracy. Our results show that when coupled with inexpensive hardware, OpenPosLib enables users to get centimetric precision on a budget.
