2.2 Project Requirements and Specifications
Once we had discussed the goals for the project, we developed a list of objectives that
provided even more specific milestones for our design. The list of objectives allowed us
to research more in-depth aspects of the project. Our objectives were laid out to serve as a
broad array of subjects that we could implement on our project.

2.3 Market Research
The capabilities of unmanned aerial vehicles continue to expand with the advent of new
technologies. Recently, UAVs proved their combat worthiness in operations over Iraq
and Afghanistan. These successes only increase the demand for the limited UAV
resources. The unmanned aerial vehicle sector has been the most dynamic growth sector
in aerospace industry. According Market research firm Forecast International claims that
the total UAV market including air vehicles, ground control equipment and payloads are
expected to be worth $13.6 billion through 2014 in the United States alone. The U.S.
military UAV market is projected to grow at a CAGR of 10% between 2010 and 2015,
says, "U.S. Military Unmanned Aerial Vehicles (UAV) Market Forecast 2010-2015,” a
new research report from Market Research Media said. The report finds that the U.S.
military UAV market will generate $62 billion revenues over the period 2010-2015.
