Abstract:
|
This paper discusses the implementation of a
modified IEEE 802.11 transceiver that is employed to enhance
the positioning capabilities of a traditional vehicle on-board
navigation unit (OBU). In this paper, we propose to use the
current wireless local access network (WLAN) as enhancing
infrastructure for ubiquitous localisation and positioning. We
describe the architecture of a localisation receiver built around a
FPGA that is capable of measuring the signal round trip time
and thus distance between itself and visible WiFi access points.
The proposed system has great potentials to enhance the
performance of traditional hardware solutions often based on
GNSS plus INS traditionally used as fundamental component in
an intelligent transportation system. The proposed system offers
vehicle-to-vehicle communication and ranging capabilities using
the current IEEE 802.11 standard. This paper describes the
details of the WLAN ranging estimation method, possible
integration approaches with a GPS plus INS system and an
analysis of the proposed system’s positioning performance in a
crowded urban environment. |
