|Abstract:||Nowadays location information is a key component for many mobile applications. In the last years smartphones evolved from using only GPS to multi constellation GNSS, by adding Galileo, BeiDou and GLONASS. Some of the most recent phones incorporate the use of dual-frequency GNSS. With the use of the additional E5a (L5) frequency, higher robustness to multipath can be achieved. Moreover, combination of the frequencies can eliminate the ionospheric effects. This paper presents the assessment of several smartphones, including three different dual-frequency ones. In frame of the test campaign live and laboratory tests were carried out, with the purpose of characterizing their performance under different environments and conditions. During live tests a SPAN system from NovAtel was used in order to obtain a precise reference solution, and for the laboratory tests a radio frequency constellation simulator (RFCS) was used. The testing activity, financed by the European Union under the Galileo Programme budget and managed by European GNSS Agency (GSA), has been performed by Airbus Defence & Space and Joint Research Centre.|
