I. Introduction
In May 2016, Google announced that GNSS raw data measurements will be available on Android smartphone devices via their latest Android Application Programming Interface (API) called Android Nougat (7.0). This innovation allowed developers and the scientific community to obtain access to GNSS measurements from embedded smartphones receiver. Code, phase, Doppler and C/N0 data can now be retrieved from Android’s mass market receivers. Following this milestone, mobile chipset manufacturers started to develop innovative technology, including the newly announced Broadcom BCM 47765 dual-frequency, multi-constellation chipset [1].
