The Global Positioning System (GPS) was initially developed by the US Department of Defence in the 1980s. Civilian use of GPS was primarily restricted to navigation, with the accuracy of the signal downgraded through Selective Availability (SA). Since May 2000, however, SA has been disabled, allowing civilian users to obtain positional fixes of much higher accuracy. This has led to improvements...

A deep neural network (DNN) is trained to estimate the speed of a car driving in an urban area using as input stream measurements from low-cost six-axis inertial measurement unit (IMU). Three hours data was collected by through city Ashdod, Israel equipped with global navigation satellite system (GNSS) real time kinematic (RTK) positioning device and synchronized IMU. Ground truth labels for we...

With the advent of location-aware smartphones, the desire for pedestrian-based navigation services has increased. Unlike car-based services where instructions generally are comprised of distance and road names, pedestrian instructions should instead focus on the delivery of landmarks to aid in navigation. OpenStreetMap (OSM) contains a vast amount of geospatial information that can be tapped in...

We address the problem of applying reactive navigation methods to non-holonomic robots. Rather than embedding the motion constraints when designing a navigation method, we propose to introduce the robot’s kinematic constraints directly in the spatial representation. In this space the Ego-Kinematic Space the robot moves as a “free-flying object”. Hence, standard reactive navigation methods appli...

Today’s car navigation systems provide driving instructions in the form of maps, pictograms, and spoken language. However, they are so far not able to support landmark-based navigation, which is the most natural navigation concept for humans and which also plays an important role for upcoming personal navigation systems. In order to provide such a navigation, the first step is to identify appro...

Since years the market of mobile navigation systems is growing enormously. Within this paper the goals and first results of the joint project “Mobile Navigation with 3D City Models” (MoNa3D; http://www.mona3d.de) are introduced. The project consortium consists of the University of Applied Science Stuttgart (coordinator), the University of Applied Science Mainz, the University of Bonn and the fo...
