last_letter : Unmanned Aerial Vehicle simulation and control packages

last_letter is a collection of ROS packages suitable for Unmanned Aerial Vehicle research, control algorithm development, non-linear physics simulation, Software-in-the-Loop (SIL) simulation and Hardware-in-the-Loop (HIL) simulation. It is developed by George Zogopoulos-Papaliakos. This document serves as a table of contents for the documentation of this congregation of ROS packages.

Scientific background

Great effort has been exerted for the simulator to be as realistic as possible. To that goal, the project incorporates bibliography related to flight dynamics, physics modeling and sensor modeling. A congreggated document discussing the modeling of a fixed-wing UAV can be found in the Modeling a Fixed-Wing UAV Github project. It is a LaTeX project with a single .pdf output document. Although uav-modeling is independent of last_letter, it will often be referred to in the documentation.
