Inertial-Based Localization for Unmanned Helicopters Against GNSS Outage

IEEE Transactions on Aerospace and Electronic Systems, 2013
Global Navigation Satellite Systems (GNSSs), such as the Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS), are the primary sensors for localization of most unmanned helicopters. However, GNSS signals cannot be tracked reliably due to geographic restrictions or deliberate jamming, and this has been an unsolved problem for

A robust state estimation method against GNSS outage for unmanned miniature helicopters

2010 IEEE International Conference on Robotics and Automation, 2010
Most unmanned aerial robots use a Global Navigation Satellite System (GNSS), such as GPS, GLONASS, and Galileo, for their navigation. However, from time to time the GNSS fails to function due to geographical restrictions and deliberated jamming. This paper proposes an Unscented Kalman Filter-based GPS/IMU integration method in order to accurately ...

Achieving Reliable Intervehicle Positioning Based on Redheffer Weighted Least Squares Model Under Multi-GNSS Outages

IEEE Transactions on Cybernetics, 2023
Achieving reliable intervehicle positioning is one of the most fundamental elements for many vehicular applications, including collision avoidance and autonomous driving. Vehicle position is generally provided by a global navigation satellite system (GNSS), which unfortunately suffers from inaccuracy to varying degrees in challenging environments, for ...
