Learning to Localise Automated Vehicles in Challenging Environments Using Inertial Navigation Systems (INS) [PDF]
Applied Sciences, 2021 An approach based on Artificial Neural Networks is proposed in this paper to improve the localisation accuracy of Inertial Navigation Systems (INS)/Global Navigation Satellite System (GNSS) based aided navigation during the absence of GNSS signals. The INS can be used to continuously position autonomous vehicles during GNSS signal losses around urban ...

Application of Initial Bias Estimation Method for Inertial Navigation System (INS)/Doppler Velocity Log (DVL) and INS/DVL/Gyrocompass Using Micro-Electro-Mechanical System Sensors. [PDF]
Sensors (Basel), 2022 This article proposes a novel initial bias estimation method using a trajectory generator (TG). The accuracy of attitude and position estimation in navigation after using the inertial navigation system/Doppler velocity log (INS/DVL) and INS/DVL/gyrocompass (IDG) for 1 h were evaluated, and the results were compared to those obtained using the ...

Inertial Navigation System Data Filtering Prior to GPS/INS Integration
Journal of Navigation, 2009 In the integration of Global Positioning System (GPS) and Inertial Navigation System (INS), the commonly used Kalman filter provides satisfactory results if both sources of information are continuously available. However, GPS outages provoke a fast degradation of precision, especially in low dynamic trajectories such as a mobile platform device held by

An analysis of a gyro-free inertial system for INS/GNSS navigation
2016 European Navigation Conference (ENC), 2016 Although the concept of determining angular velocity out of the readings of multiple, displaced accelerometers is not new, apparently it has not yet matured into practical technologies. A new generation of low-cost MEMS accelerometers, which is expected to breakthrough in the next years, may enable gyro-free navigation in small platforms such as UAVs ...

Calf-INS: A Calf-Mounted IMU-based Inertial Navigation System for Pedestrian
, 2023 <p>Pedestrian dead reckoning based on a wearable inertial measurement unit (IMU) is an important part of the pedestrian positioning system because it is not affected by the external environment. However, step model-based methods have the problems of low positioning performance, and zerovelocity update (ZUPT) based methods (i.e., foot-mounted ...
