Situm algorithm upgrades for faster calibrations in large buildings

Situm’s indoor location is an easy, quick to implement solution for large buildings. To install it, you need a calibration that collects the data transmitted by router signals and Bluetooth beacons. After merging these signals with the smartphone’s inertial sensors data, you can enable the positioning that allows guiding people or monitoring work teams. The latest improvements allow lightening this calibration process and validate the indoor navigation in a smoother and faster way.

In large buildings, such as airports, large hospital complexes, or corporate headquarters and campuses, the amount of geolocation data is massive. To record it, you need to perform a calibration, a process for which we have the Situm Mapping Tool app.

The app collects the data coming from the signals of routers and Bluetooth beacons, and that information is uploaded to the location system in the cloud for processing. This first phase, in which the signal model begins to be generated, is called training or signal map generation.

Improved signal filtering to optimize the weight of collected data  

Situm’s indoor geolocation is a system constantly evolving and improving. This time it was the turn of the training process to reduce the errors that could occur when the amount of information exceeded expectations.

Of course, the larger the building, the more signals you need to record so that the indoor navigation or the monitoring of work equipment can operate correctly. And the more data, the more likely it is that the training process may slow down or even be interrupted. It is very similar to what happens when we process a very file on our computer, and it crashes.

The latest improvements in Situm’s algorithm optimize the weight of all these data thanks to better signal filtering. By selecting the most useful signals, we lighten the process and increase the system’s stability.

Indoor navigation calibration

This improvement also means that the calibration process and indoor navigation tests can be carried out more quickly and smoothly.

All information about Situm Mapping Tool and the calibration process is available in our documentation.

If you manage a large building and are interested in implementing indoor guidance for your visitors or monitoring or auditing work teams, do not hesitate to contact us.
