More and more sensors and receivers are found nowadays in
modern smartphones which can enable and improve positioning for Location-
based Services and other navigation applications. They include multiconstellation
GNSS (Global Navigation Satellite Systems) receivers and
other sensors which can be employed for positioning. The state-of-the-art
thereby is that dual frequency GNSS capable receivers in smartphones are
now recently on the market. With these receivers not only the current 3D
positions but also the raw data of the measurements can be utilized leading
to higher positioning accuracies. New algorithms need to be developed to
make use of the measured GNSS raw data to be able to achieve required
positioning accuracies. Therefore, the goal of our research concept is to develop
a methodology based on dual frequency GNSS/Wi-Fi smartphone
(L1/L5 carrier phases and 2.4/5 GHz frequency bands) for supporting
seamless out/indoor navigation. A methodology for processing the measurement
results based on fusion of these techniques, its significance and the
expected findings are presented in the paper.
