% Small Fixed-Wing UAV State Estimation Examples
%
% This code provides example methods for performing state estimation
% (i.e. position and orientation) of a fixed-wing UAV (Unmanned Aerial
% Vehicle) using GPS, gyros, accelerometers, and a magnetometer as sensors.
% This code is meant as a companion to the JHU/APL Technical Digest article
% "Fundamentals of Small Unmanned Aircraft Flight", by Jeff Barton (see Reference 1).
