|Abstract:||This paper examines the usage models, WiFi correction of GNSS multipath effects, ‘time of view’, vehicle infrastructure, and WiFi access point infrastructure build-out constraints on the use of WiFi positioning as an augmentation for automotive original equipment manufacturers GNSS receivers in urban canyon environments. Special emphasis is given to coverage constraints, dynamic effects, and evaluations of WiFi signal quality and availability in dense urban canyon settings. Of interest is the area of coverage and time in view of available WiFi access points in a typical urban canyon environment and how that affects the overall positioning solution. The paper covers five main topics: architecture of a WiFi-augmented GNSS solution; application focus of current GNSS+WiFi positioning solutions; automotive WiFi positioning constraints; test rig setup; and trial runs in Chicago’s urban canyon.|
