Autonomous Aerial System (UAV) for Sustainable Agriculture: A Review

Drones are now a days emerging as a component of precision agriculture along with contributing to sustainable agriculture. The use of advanced technologies such as drone in agriculture offer potential for facing several major or minor challenges. The major applications of drone in agriculture are spraying, irrigation, crop monitoring, soil and field analysis and bird control. The objective of this paper is to review the latest trends and applications of leading technologies related to agricultural UAVs equipment, and sensors development. And also, the use of UAVs in real agricultural environments. Based on the literature, found that a lots of agriculture applications can be done by using Drone. In the methodology, we used a comprehensive review from other researches in this world. Furthermore, the future development of agricultural UAVs and their challenges are considered. In this review paper, summarizes the available agricultural drones and applications of UAVs for Precision Agriculture using different sensors to evaluated agricultural parameters such as NDVI, vegetation index, NIR, nutrient disorder using sensors like RGB, digital camera, multispectral and hyperspectral sensors and to reduce the wasting of water and chemicals quadcopter, hexacopter UAVs could be used.
