The Geoloc_Indoor project is handled from years to years by Polytech Students. For the year 2016-2017, the project is handled by Gambro Antoine et Cochino Louis and directed by Donsez Didier.




Project presentation

Nowadays, geolocalisation has become a wide spread technology. It is used in order to guide a user from a first point A to another point B, naming it can allow users to have routing help during a travel, such as driving trip or even going to a coffee. In this way, geolocalisation is incredibly well spread outdoor, it's in this case that geolocalisation is the most efficient. But, what about indoor geolocalisation ? Because of the use of satellites and GSM networks to locate an object, it is a harder to use it indoor. Buildings prevent signals to enter making impossible to locate things with those means. And this where our project takes place !


This project is directed by Didier Donsez and designed by Antoine Gambro and Louis Cochino. Both are currently studying in their first year of Polytech master degree. The project is part of the Software Development course.
