LiDAR/Visual SLAM-Aided Vehicular Inertial Navigation System for GNSS-Denied Environments

International Conference on Communications, Signal Processing, and their Applications, 2022
Most navigation systems in GNSS-challenged environments rely on GNSS/INS integrated navigation system, with the INS potentially providing reliable positioning during short GNSS outages.

An enhanced GNSS/INS navigation compensation method using LSTM-FPN for bridging GNSS outages

Measurement Science and Technology
Abstract The integrated navigation system combining the Global Navigation Satellite System (GNSS), and Inertial Navigation System (INS) is extensively utilized for navigation and positioning, yet it encounters significant accuracy degradation in a GNSS-denied environment due to interference with the GNSS signals.

GPS/GNSS Consistency in a Multi-path Environment and During Signal Outages

2015 IEEE 18th International Conference on Intelligent Transportation Systems, 2015
The majority of Intelligent Transportation System (ITS) applications require an estimate of position, often generated through the fusion of satellite based positioning (such as GPS) with on-board inertial systems. To make the position estimates consistent it is necessary to understand the noise distribution of the information used in the estimation ...

An Enhanced Vehicle Self-Positioning Method During GNSS Outages Using Factor Graph Optimization and CNN-LSTM-Attention

IEEE Transactions on Instrumentation and Measurement
Integration of inertial navigation system (INS) and global navigation satellite systems (GNSS) is a promising approach to vehicle self-localization. However, such a scheme may have poor performance during GNSS outages, and the errors of INS also disperse

Enhanced Fixed Wing UAV Navigation in Extended GNSS Outages using a Vehicle Dynamics Model and Raw GNSS Observables

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2019
This paper presents the design and testing of an innovative approach to the navigation of fixed wing Unmanned Aerial Vehicles (UAVs) using a Vehicle Dynamic Model (VDM) based, tightly coupled INS/GNSS architecture. The investigation focuses on lowmass (sub 30 kg) and low cost (sub $12,000) applications.

Vision-aided intelligent and adaptive vehicle pose estimation during GNSS outages

Measurement Science and Technology
Abstract In this paper, a novel multi-information fusion methodology is proposed for vehicle pose estimation. The purpose is to improve the pose estimation accuracy during global navigation satellite system (GNSS) outages, mainly from two aspects: (1) extra observations of accurate velocities and angular rates without cumulative errors; (
