Guidance Navigation and Control for Quadrotor UAV Using Lyapunov-Based Backstepping. [PDF]

Sensors (Basel)
Quadrotor UAVs present a significant control challenge due to their underactuated nature; strong coupling effects; nonlinear dynamics; and high sensitivity to unknown effect parameters, external disturbances, and uncertainties.

Adaptive filtration of the UAV movement parameters based on the AOA-measurement sensor networks

International Journal of Aviation, Aeronautics, and Aerospace, 2020
Currently, the urgent task is to assess the small-sized maneuvering UAVs movement parameters. The location of an unknown UAV as a radio source can be determined using AoA measurements of the wireless sensor network.

Adapted D* Lite to Improve Guidance, Navigation and Control of a Tail-Actuated Underwater Vehicle in Unknown Environments

IEEE Access, 2023
Biomimetic Autonomous Underwater Vehicles (BAUVs) navigate aquatic environments by mimicking natural propellants from fish species. These vehicles move part(s) of their bodies using various mechanisms to propel and swim forward or laterally.

Electro-dynamic analysis of 60mm mortars modified with guidance, navigation, and control components [PDF]

2010 IEEE Antennas and Propagation Society International Symposium, 2010
This paper summarizes the results from numerical analyses of 60mm mortar projectile bodies that are modified with guidance, navigation, and control (GNC) hardware. The major findings from the study include: 1) the far field radiation patterns predicted for the projectile considered in this analysis are sensitive to the overall size and shape of the ...

The Impacts of Advanced Avionics on Degraded Visual Environments

International Journal of Aviation, Aeronautics, and Aerospace, 2023
Degraded visual environments (DVE) such as brownout, sand storms, and night conditions are responsible for accidents and hence losses in the aviation industry. There is a need to develop avionic systems to support pilots when they encounter environmental

Navigation and guidance control system of UNUSAITS AUV based on dynamical system using ensemble kalman filter square root

Journal of Physics: Conference Series, 2020
Abstract This study presents the development of navigation system of AUV. It is initially in the form of a nonlinear system model to determine the trajectory for the AUV motion control. The non-linear system model of UNUSAITS AUV is then implemented in the Square Root Ensemble Kalman filter (SR-EnKF) to estimate the trajectory of the AUV.

Guidance, Navigation, and Control for Fixed-Wing UAV

Mathematical Problems in Engineering, 2021
The purpose of this paper is to develop a fixed-wing aircraft that has the abilities of both vertical take-off (VTOL) and a fixed-wing aircraft. To achieve this goal, a prototype of a fixed-wing gyroplane with two propellers is developed and a rotor can ...
