1. Tracking of Sinking Underwater Node using Inertial Navigation
Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknikSammanfattning : Tracking objects underwater is prone to error since no equivalent system to GPS exists for underwater applications. Accurate positioning is vital for conducting surveillance. However, it is hard for a system to keep an accurate prediction while moving without a GPS source. LÄS MER
2. Applying Deep Learning To Improve Optimization- Based Approaches For Robust Sensor Fusion
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Recent studies show that deep learning can be employed to learn from sensor data to improve accuracy and robustness of sensor fusion algorithms. In the same vein, in this thesis we use a state-of-the-art temporal convolution network to predict zero velocity updates (ZUPT) from raw inertial measurement unit (IMU) signals, and use the network output to improve the performance of an optimization-based pose estimator.

3. Development and Testing of Performance Assessment Equipment for Elite Fencers
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The main purpose of this thesis is to use a low-quality inertial sensor, whichonly provides 3-D acceleration and 3-D angular velocity, to have good poseestimation results, which is to track the orientation, the velocity and the displacementof some fencing relevant movements. This thesis focuses on twomain parts, algorithms for pose estimation and algorithms for re-calibration ofboth the accelerometer and the gyroscope. LÄS MER
4. Distance estimations by non-linear step length models using accelerometer sensor data from waist-worn smart-phones
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : This thesis examines the possibility of modelling trajectory and estimating distance during a walk using only a smart phone attached to the waist. Due to GPS not functioning indoors, a navigation system without the need of external communication could be the perfect complement for closed spaces. LÄS MER
5. Aided inertial navigation field testsusing an RLG IMU
Master-uppsats, KTH/GeodesiSammanfattning : In this thesis a system for aided inertial navigation (aided INS or AINS) has been testedthrough a number of kinematic experiments. In the experiments, data was collected andpost-processed by different methods. The system was built up by an IMU (inertial measurementunit) aided by a GPS receiver and an odometer. LÄS MER
