A Novel V2V Cooperative Collision Warning System Using UWB/DR for Intelligent Vehicles

Sensors, 2021
The collision warning system (CWS) plays an essential role in vehicle active safety. However, traditional distance-measuring solutions, e.g., millimeter-wave radars, ultrasonic radars, and lidars, fail to reflect vehicles’ relative attitude and motion ...

MEMS 3D DR/GPS Integrated System for Land Vehicle Application Robust to GPS Outages

IEEE Access, 2019
In this paper, we propose a MEMS 3D DR/GPS integrated system which provides 3D attitude and position information for land vehicle application. Since low-cost MEMS-IMU provides data with large bias, it is hard to obtain an accurate position of the land ...

Step by step: reconstruction of terrestrial animal movement paths by dead-reckoning [PDF]

, 2015
Background: Research on wild animal ecology is increasingly employing GPS telemetry in order to determine animal movement. However, GPS systems record position intermittently, providing no information on latent position or track tortuosity.
