Autonomous unmanned aerial vehicles (UAV) are becoming
increasingly capable nowadays and the complex mission
tasks that are carried out by UAVs are far more critical than
before. One of the basic tasks for an autonomously flying
vehicle is to reach a desired location in space in an unsupervised
manner because precise trajectory tracking is required
to perform more complex missions in unconstrained environments.
Recently significant interest in unmanned aerial
vehicles directed researchers towards navigation problem of
flying vehicles.
