The term UAV has been used for several years to describe unmanned aerial systems. Various deﬁnitions have been proposed for this term, like : A reusable1 aircraft designed to operate without an onboard pilot. It does not carry passengers and can be either remotely piloted or pre-programmed to ﬂy autonomously. Recently, the most reputable international organizations – like the International Civil Aviation Organization (ICAO), EUROCONTROL, the European Aviation Safety Agency (EASA), the Federal Aviation Administration (FAA) – as well as the US Department of Defense (DoD), adopted unmanned aircraft system (UAS) as the correct ofﬁcial term.
Indeed, major defense contractors are involved in developing and producing UAVs (like Boeing, BAE Systems, Lockheed-Martin and EADS). At the same time, newer or smaller companies have also emerged with innovative technologies that make the market even more vibrant. US companies currently hold about 63–64% of the market share, while European companies account for less than 7% . In 2005, some 32 nations were developing or manufacturing more than 250 models of UAV, and about 41 countries were operating more than 80 types of UAV, primarily for reconnaissance in military applications .
R Commercial applications. These include aerial photography, precision agriculture– chemical spraying, transportation of goods and post, etc. 5 UAS Market Overview Summarizing, UAS can offer major advantages when used for aerial surveillance, reconnaissance and inspection in complex and dangerous environments. Today, there are several companies developing and producing hundreds of UAV designs. Indeed, major defense contractors are involved in developing and producing UAVs (like Boeing, BAE Systems, Lockheed-Martin and EADS).
