MEMS IMU Error Mitigation Using Rotation Modulation Technique

Sensors, 2016
Micro-electro-mechanical-systems (MEMS) inertial measurement unit (IMU) outputs are corrupted by significant sensor errors. The navigation errors of a MEMS-based inertial navigation system will therefore accumulate very quickly over time.

Inertial Measurement Units (IMUs) in Drowning Prevention: An Exploratory Study

International Journal of Aquatic Research and Education, 2015
The use of inertial measurement unit (IMUs) sensors in competitive swimming movement analysis has become increasingly popular but has not been applied to measuring water competencies related to drowning prevention. This study explored the potential use of IMU sensors in three simulated water competency activities in a pool environment.

Extended Kalman Filter-Based Methods for Pose Estimation Using Visual, Inertial and Magnetic Sensors: Comparative Analysis and Performance Evaluation

Sensors, 2013
In this paper measurements from a monocular vision system are fused with inertial/magnetic measurements from an Inertial Measurement Unit (IMU) rigidly connected to the camera. Two Extended Kalman filters (EKFs) were developed to estimate the pose of the
