Low Cost Surveying Using an Unmanned Aerial Vehicle

Traditional manned airborne surveys are usually expensive and the resolution of the acquired images is often limited. The main advantage of Unmanned Aerial Vehicle (UAV) system acting as a photogrammetric sensor platform over more traditional manned airborne system is the high flexibility that allows image acquisition from unconventional viewpoints, the low cost in comparison with classical aer...

Low-cost Modular Unmanned Aerial Vehicle Control Unit

This paper described design, development, tuning and verification of a low-cost control unit for small unmanned aerial vehicle developed at the Department of Control Engineering, FEE CTU in Prague within a students project. This control unit can be used for control of fixed wing aircraft as well as helicopters, multi-rotor vehicles or blimps or other type of vehicles. Such vehicles can be built...

Visual-Inertial based autonomous navigation of an Unmanned Aerial Vehicle in GPS-Denied environments

An Improved Alignment Method for the Strapdown Inertial Navigation System (SINS)

In this paper, an innovative inertial navigation system (INS) mechanization and the associated Kalman filter (KF) are developed to implement a fine alignment for the strapdown INS (SINS) on stationary base. The improved mechanization is established in the pseudo-geographic frame, which is rebuilt based on the initial position. The new mechanization eliminates the effects of linear movement erro...
