Dead Reckoning GPS

Overview

GPS positioning works well when at least four satellites are in line of sight. However, in urban environments where quality of GPS navigation is crucial, the view to the sky is obstructed frequently or high-rise buildings reflect GPS signals causing severe multipath effects. As a consequence, the quality of GPS is deteriorated. u-blox Sensor-Based Dead Reckoning technology with the Enhanced Kalman Filter (EKF™) algorithm is the solution of choice for navigation systems, fleet management and GPS-based road pricing systems.

Coverage	100% road coverage without interruptions
Accuracy	Superior accuracy regardless of quality of GPS signal
Ease of use	Easy installation and interfacing, no manual configuration

The superior dead reckoning performance has been proven in the most challenging urban environment:
