• Abstract:
  For many roadway applications, high-accuracy in-lane level vehicle position information is desired. Unfortunately, in many roadway environments GPS dead zones hinder sufficient GPS position accuracy. These roadway environments include underpasses, tree canopies, urban canyons, and any other locations where the view to the sky is limited. This report introduces a high-accuracy position estimator that augments GPS in areas where short-term (< 200 meter and < 15 second) GPS dead zones exist. The position estimator fuses differential GPS (DGPS) position measurements, yaw rate measurements, and two-dimensional velocity measurements to provide in-lane level accuracy position estimates. The estimator increases the availability of high-accuracy position estimates for applications that demand continuous high-accuracy in-lane level positioning, such as lane departure warning systems.
