Calibration of Smartphones for the use in indoor navigation

The HafenCity University has been working for quite some time with the possibilities for indoor positioning with the focus on the use of current smartphones. Latest smartphones, as in this paper the Samsung Galaxy Nexus, include necessary sensors for relative positioning. These sensors will be analyzed before implementing an indoor navigation by using a smartphone. Hereinafter the gyroscope and the barometer are investigated. An approach for the calibration of the gyroscopes using a total station as well as a view on the possibility of storey detection via air pressure measurements will be shown in the following.
