Over the past few years, there has been an increase in the use of Unmanned Aerial Vehicles (UAVs). The various advantages of UAVs are safety in airspace and their ability to enable the beyond visual line of sight operation. According to the market intelligence report by BIS Research titled, ‘Global UAV Sense and Avoid System Market-analysis and Forecast (2017-2022),’ the market for UAV sense and avoid system accounted the value $508.7 million in the year 2016 million, with commercial application holding the highest share. The prominent share of the commercial sector is attributed to the rise in demands of drones equipped with sense and avoid system across commercial applications such as inspection, delivery, first responder, and aerial imaging, among others.
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.
