We at the Universität der Bundeswehr, Neubiberg have been extensively working on performing RTK positioning with the Smartphone raw measurements. In order to compensate for the multipath effects from the ground reflection and destruct the reflected waves traveling parallel to the ground plane, which is somehow a major degradation factor in smartphone positioning. We performed an out of the box experiment by performing different sets of experiments with the smartphone. A few of them are listed below.

Experiments list
