METHODOLOGY FOR THE POSITIONAL ACCURACY ASSESSMENT OF GNSS TRACKING DATA COLLECTED FROM NAVIGATION RECEIVERS

Currently, the navigation receivers are very common in daily activities. It can be cited several specific devices for localization (Garmin, TomTom, among others), as well as in telecommunications devices (smartphones, tablets, etc.). This work aimed to assess the planimetric positional accuracy of the navigation receivers Garmin ETrex Vista Hcx and Smartphone Samsung Galaxy S7 Edge, applying the Equivalent Rectangle Method (ERM), considering the reference lines obtained simultaneously by the kinematic relative positioning of a pair of geodetic receiver Trimble R6 with greater accuracy. The results show that the smartphone has positional accuracy next to the Garmin and the tracking data of the two receivers can be applied in activities requiring PEC-PCD class "A" on the Scale: 10,000.
