The purpose of a navigation system installed on a car is to help drivers in order to select an optimal path to reach the destination. In most of these systems, Global Positioning System (GPS) are used to determine vehicle position. There are number of error sources that undermine the quality of GPS measurements for car navigation systems. For this reason, technique like Map Matching (MM) is req...

Due to the satellite signals are blocked, it is difficult obtain vehicle position in tunnels. We propose a single-site localization scheme for rectangular tunnel environment, where most satellite-based positioning methods can not provide required accuracy. In non-line-of-sight (NLOS) scenarios, we make use of reflection paths as assistants positioning. Specifically, first, virtual stations esta...

Global Positioning System (GPS)-equipped probe vehicles have been one of the principal techniques in detection of traffic flow. In order to guide the application of the different methods using data from GPS probe vehicles, this paper compares two of the most popular methods using the GPS data to estimate traffic statethe method of tracking probe vehicles, and the one of fitting the model with t...

In this paper, we survey the global positioning system (GPS)-less vehicular localization methods using dedicated short range communication (DSRC). Time of arrival (TOA), which is one of the radio-based ranging techniques, is used in the methods to localize a vehicle. Through the localization methods using DSRC, vehicles can handle GPS error or the situations of no GPS location data when they ar...

This thesis begins with a survey of current state-of-the art in-car navigation sys-tems. The pros and cons of the four commonly used information sources –GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map in-formation – are described. Common filters to combine the information from thevarious sources are discussed.Next, a GNSS-aided inertial navigation ...

The novel Multi-Receiver Vector Tracking (MRVT) architecture for the joint tracking of multiple GPS receivers, presented in our prior work [1], is improved upon in this followup paper. Improvements include an augmented software platform, Python Software Defined Radio (Python SDR), which has, among its many enhancements, a variable coherent integration interval with navigation bit wipe-off. Dyna...

Recently, Small Unmanned Aerial Vehicles (SUAV) are used in a variety of reconnaissance, surveillance, combat applications and so on. Tracking and positioning ground moving targets using a camera mounted on SUAVs has important applications in military and civilian purposes. Although many approaches for a vision-based target positioning system have been developed, most researches are limited to ...

During the last decade with the rapid increase in indoor wireless communications, location-aware services have received a great deal of attention for commercial, public-safety, and a military application, the greatest challenge associated with indoor positioning methods is moving object data and identification. Mobility tracking and localization are multifaceted problems, which have been studie...
