The modern world has engineered one of the most advanced technologies in aeronautics, as sometimes there is a dire need for Unmanned Aircraft Systems or UAV–Unmanned Aircraft Vehicles. Moreover, it can be used for several things, including geospatial data gathering (Barnhart et al., 2012). This gives a chance to take a closer look at the environment and allows an option in better controlling natural and human made disasters. With relatively few problems, the benefits of using UAS have many advantages over the traditional piloted technology. Primarily, there are several types of UAVs. Some of them have an automatic control while others are remotely controlled “drones”. There are several important criteria that play a role in the purpose of the UAV. Parameters like mass, time, distance of flight and height, are all determinants in the design and function of the vehicle. One of the uses is for the monitoring of disasters, combined with a low deployment cost. The sensors on the UAVs provide important information that can be used in prediction of a cataclysm. The data is stored and analyzed which results in a mapping of the objective and effective response. There are also two types of takeoff—one is vertical (VTOL), the other is conventional (CTOL) (Barnhart et al., 2012). VTOL is more maneuverable which gives it an advantage with the change in atmospheric and other physical conditions. Because they are easy to deploy, the number is rather high, giving a chance to cover large areas and analyze greater amounts of information. The sensors on UAVs have several uses, from video recording, to scanning of radiation levels and infrared rays. In the end, the types of sensors that are going to be used need to be in working balance with the mass of the UAV. Not only there is an ability to record and store information, a person can watch a live feed from the camera’s mounted on the UAV. One of most valued functions of the UAVs is that it has become one of the widely used defense systems and has proven to be very effective. It creates many possibilities of control and lowers the risk of an attack. The United States have focused on the development of strategic advances that could deliver maximum field effectiveness and safety for the army personnel. The characteristics of flight also differentiate types of controls used in defense or combat. The navigation system itself gives a unique use to each UAV, not to mention the propelling forces and several other parameters (Rasmussen, 2009). The link to the satellite makes the UAV very useful in receiving data from several sources and quick manipulation and adjustments to the flight and destination characteristics. The fact that all equipment is digital, allows for precise and reliable identification of the needed data. The United States is one of the recognized leaders in UAVs and their use in all sorts of missions. The primary concern is the safety of the country, so more than half of all air force consists of UAVs (Austin, 2011). The lower costs when bought in bulk, as well as an impressive length of flight make it a perfect possession to the army, not to mention the safety of the operators.
