Owl Positioning System

OwlPS (Owl Positioning System) is a positioning (localization) system based on the IEEE 802.11 radio network (Wi-Fi), targeting mainly indoor environments. It uses an infrastructure-centred architecture, which means the infrastructure does the measurements and computes the mobile terminals' positions, rather than the terminals computing their own positions (as it is the case for instance with the GPS).

OwlPS implements various positioning techniques and algorithms based on the radio signal strength. It features a self-calibration (or autocalibration) mechanism that avoids the time-consuming manual fingerprinting phase and allows considering dynamic changes of the environment (human, climatic, etc.) when computing the location of mobile terminals.

This presentation is an excerpt of doc/owlps.t2t. Please refer to this file for a more in-depth introduction to OwlPS.


OwlPS is not currently actively maintained, as I'm not working on indoor positioning at the moment, but I'll happily consider any contribution (or job offer).

The CHANGELOG file lists the changes that occurred in OwlPS, version by version, since its early stages.

Note on the t2t file extension

Most of the documentation in this repository is provided as text files in the txt2tags format (*.t2t files). You can convert them to various formats (HTML, man pages, etc.) using the txt2tags utility; if you mind the markup tags, you can even strip them using the txt output.
