No GPS? Ubihere will find what you seek anyways! Revenue is beginning to flow for a startup launched out of Ohio State University and incubated at Rev1 Ventures. Research for spies and astronauts undergirds Ubihere, a startup deploying commercialized location systems for a variety of applications. Ubihere has its roots in research by Alper Yilmaz’s …
GPS-Denied Geo-Localization Using Visual Odometry The primary method for geo-localization is based on GPS which has issues of localization accuracy, power consumption, and unavailability. This paper proposes a novel approach to geo-localization in a GPS-denied environment for a mobile platform. Our approach has two principal components: public domain transport network data available in GIS databases …

persistent-feature-tracking-using-scene-geometry Despite many alternatives to feature tracking problem, iterative least squares solution solving the optical flow constraint has been the most popular approach used by many in the field. This paper attempts to leverage the former efforts to enhance feature tracking methods by introducing a view geometric constraint to the tracking problem. In contrast to …

A Multi-Sensor Integration Approach Toward Astronaut Navigation For Landed Lunar Missions. As experienced by Apollo lunar astronauts, spatial orientation can be affected significantly by lunar environmental conditions such as the moon’s altered gravity, lack of an atmosphere, limited spatial references, and different level of reflectivity. To help overcome these challenges, a lunar astronaut navigation system …
