Indoor positioning system

The correct positioning of elements inside a warehouse or factory offers us many possibilities in the area of ​​process digitization. The problem is that the GPS system is no longer an option and there are also interferences that make this task difficult when we talk about industrial environments.
This project has as its origin an open innovation challenge proposed by ArcelorMittal, which selects us for its resolution. The objective was the application of technologies that allow the positioning of an autonomous indoor drone that would carry out previously established routes.
