French space agency CNES has made available two applications on the Google Play store for Android apps. Both are compatible with Android N (Nougat).
RTCM Converter: This app aims to convert the smartphone GNSS raw measurements to Radio Technical Commission for Maritime Services (RTCM message type 1077) and send them to a caster, for use by third-party software.
PPP WizzLite: This app is a port of the CNES PPP client (code and Doppler only, light version) on Android. Accuracies of 1-2 meters can be reached in kinematic mode, and sub-meter in static mode (using external SBAS data). To do so, users need to pull external RTCM streams for orbits/clocks corrections and broadcasts, such as ones available from the International GNSS Service Real-Time Service (IGS RTS).
Both apps have been validated on a Nexus 5X device with no phase support.
