Resumen
The purpose of the titration work was to determine and compare the accuracy of mid-range and high-end mobile device in standard positioning service (SPS) operation modes and the assisted global positioning service (A-GPS) in external and internal scenarios central places of the city of
Riobamba, for this, two fundamental stages were taken into account, in the first one GPS receivers integrated in the Samsung Galaxy S8 and Huawei P10Lite were used, which were used for the extraction and storage of raw data, phase two an interface was made graph in MatLab that allows
the processing of measurements of latitude, longitude, availability of visible satellite (SVid) and signal-to-noise reaction (SNR), taken in four scenarios considered important for their location. The accuracy achieved in the internal scenario is 9.68m for SPS compared to 8.39 for A-GPS, for
the external scenario there was an error of 2.65m versus 2.19m respectively, the reduction of the error that occurs in the external scenario with a reduction of 17.37% and internally the reduction of the error that presented in external scenario with a reduction was 13.32% thanks to the
correction received by the mobile network, On the other hand, the performance of the 95%, while the mid-range device obtained a 90% performance for outdoor navigation and 55% indoors. It is recommended to do the field study with different conditions and taking into account new
scenarios.
