At the inception of Unmanned Aerial Vehicle (UAV) in the 20th century, the UAVs were utilized specifically for military purposes. But with the passing time and advancements in various technologies, the UAVs now serve multiple purposes besides military application. The UAVs have witnessed a significant reduction in size and weight over the last decade, which has consequently reduced the cost of manufacturing. Besides these developments, the battery life has also been enhanced considerably along with the degree of autonomy for these vehicles. As a result of these developments, UAVs now have a wider range of applications in different commercial and non-commercial sectors. According to our recent market intelligence report ‘Global Unmanned Aerial Vehicle (UAV) Market Value and Volume: Analysis and Forecast (2017-2021)', the global UAV market accounted for a market value of $8.02 billion in 2016 with small UAVs holding the highest share.
Drones have spread their utility across various industries and unmanned aerial vehicles are now being used for non-military purposes as well, such as, oil and gas pipeline surveillance, wind mill monitoring, and crime surveillance. This phenomenon has definitely changed the industrial scenario globally, but on the other hand this has led to an increase in air traffic. To tackle the problem of air traffic, the demand of UAV sense and avoid system has escalated over a few years, which prevents drones from colliding with each other, or heading towards other obstacles, causing collateral damage.
