Abstract
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.

AND MOTIVATIONSince its inception with the Navy Navigation Satellite System (Transit) [1], satellite navigation has become an integral part of our life
Because of the increasing reliance on positioning systems, several countries started to develop their own, such as the Global Navigation Satellite System (GLONASS), Galileo and BeiDou Navigation Satellite System (BDS). These multiple positioning systems come under the generic term of Global Navigation Satellite System (GNSS)
To enable end-users and application developers to reap the benefits of centimetric positioning, we propose OpenPosLib, an open source library that aims to fill the gap between all the components needed to achieve centimetric accuracy and the user-facing application
Summary
AND MOTIVATIONSince its inception with the Navy Navigation Satellite System (Transit) [1], satellite navigation has become an integral part of our life. Because of the increasing reliance on positioning systems, several countries started to develop their own, such as the Global Navigation Satellite System (GLONASS), Galileo and BeiDou Navigation Satellite System (BDS). With the generalization of positioning systems, new use cases began to emerge: Augmented Reality games such as Pokemon Go, Geocaching [3], sport tracking [4], precision agriculture, etc. This resulted in new requirements in terms of accuracy. Many techniques have been used to determine these geographic positions, from celestial navigation, map and compass, sextant and chronometer up to radar navigation These technologies had a lot of inaccuracies, resulting in loss of fuel and time and sometimes accidents. We introduce the relevant positioning technologies used in this project
