Over the last few years, research had been conducted on how to develop basic mobility aid for visually impaired and blind people using vision and image processing techniques. However, our research at Geodetic Engineering Laboratory has taken a different vi ...
In this paper a new method for gyroscopic sensitivity evaluation of a vibrating angular rate sensor is presented. This method is used to evaluate the angular rate sensitivity of a four-beam-bridge gyroscope realized at IMT Neuchatel [ii. The frequency spli ...
Applications of global navigation satellite system (GNSS) in land transportation systems are already extensively deployed and will certainly continue to grow especially in the framework of intelligent transport systems. However, one of the best-known drawb ...

A displacement of a pedestrian is determined from his or her accelerations by detecting accelerations which is substantially non vertical, determining a characteristic feature in the detected accelerations correlated with a step frequency, determining the ...
This research has been sponsored by the Centre Suisse d'Electronique et de Microtechnique (CSEM) in Neuchâtel, Switzerland. It introduces a system and the algorithms for Pedestrian Navigation using a combination of sensors. The main objective is to localis ...
In this paper, we present the development and the implementation of algorithms to access map databases by a user equipped with a pedestrian navigation system. ...
The challenge of knowing one's position in a precise and reliable way, at any time, with and without reception of satellite signals, represents an area fairly explored for the navigation of vehicles. To widen this service to the pedestrians requires a diff ...
When satellite are available, the localisation of a pedestrian is fairly straightforward. However in cities or indoors, dead reckoning systems are necessary to determine the user's position. Our current research focuses on the development of algorithms and ...

The gravity field may be determined using different techniques, but airborne gravity surveying is becoming a powerful tool mainly due to its potential in remote areas. One of the main problems in airborne gravity is the separation of the vertical accelerat ...
