On the calibration aspects of MEMS-IMUs used in micro UAVs for sensor orientation

We introduce a three step procedure to improve attitude determination by MEMS-IMU sensors on board a small UAV. IMU pre-calibration is performed first and only once in the lab; second in a simplified version and for every switch-on in the field. Together, ...

Calibration Aspects of INS Navigation

Philipp Clausen

The use of a Bayesian filter (e.g., Kalman filter) for the fusion of information from satellite positioning and inertial navigation is a common approach in many applications, where the knowledge of position, velocity, and attitude in space are of great int ...

Construction of Dynamically-Dependent Stochastic Error Models

Jan Skaloud, Stéphane Guerrier, Philipp Clausen

Stochastic behavior of an instrument is often analyzed by constructing the Allan (or wavelet) variance signatures from an error signal. For inertial sensors, such a signature is conveniently obtained by recording data at rest. The analysis of this signal w ...

An overview of a new sensor calibration platform

Jan Skaloud, Stéphane Guerrier, Philipp Clausen

Inertial sensors are increasingly being employed in different types of applications. The reduced cost and the extremely small size makes them the number-one-choice in miniature embedded devices like phones, watches, and small unmanned aerial vehicles. The ...

Assessment of positioning accuracy of vehicle trajectories for different road applications

Pierre-Yves Gilliéron, Philipp Clausen

Global navigation satellite systems (GNSS) has become a kind of positioning standard due to the high penetration rate of this technology on mass market intelligent transportation systems (ITS) applications. However, this positioning technique remains a rea ...

Position accuracy with redundant MEMS IMU for road applications

Bertrand Merminod, Pierre-Yves Gilliéron, Jan Skaloud, Philipp Clausen

Traffic problems have mainly resulted from an increase in mobility over the last decades involving an increase in traffic congestion and degradation of environmental conditions. The employment of new systems - namely, Intelligent Transport Systems (ITS) is ...

Ein Mikroflugzeug zur genauen Kartierung ohne Passpunkte am Boden

Jan Skaloud, Philipp Clausen, Martin Rehak

Diese Studie soll das Potential von Navigationstechnologien aufzeigen. Diese Tech nologien werden zur Bestimmung der Position und der Ausrichtung von Mikrodroh nensystemen (Micro Aerial Vehicle, MAV) genutzt, deren Gewicht 5kg nicht über schreitet. Dies ...
