Investigation of collision warning possibilities by means of GNSS receivers of Android smartphones

Abstract

Using of raw GNSS measurements in Andoid smartphones for precise mututal positioning of vehicles on a road is considered in the Paper. Field experiments with two moving vehicles and pedestrian were conducted. 15 kinds of general maneuvers were provided (overtaking, turn, oncoming traffic, etc.). Smartphone measurements were logged and post-processed to get mutual positioning estimations during maneuvering. Smartphone estimations were compared with precision GNSS receivers measurements.
