In recent years, there are more and more applications of drones in civilian applications, and countries are gradually opening up in the civilian aspects of drones. UAV has been widely used in many fields, such as public safety, emergency search and rescue, agriculture and forestry, environmental protection, transportation, communications, meteorology, film and television aerial photography and so on. 

In the past few years, the UK has issued permits to more than 130 companies and government agencies, while the US has issued more than 1400 permits. There is no doubt that with the update and development of technology, civil UAV will usher in the blowout development, and the application prospect is very broad.

The international UAV benchmark countries and their development are as follows: 

America. 

National Aeronautics and Space Administration ((NASA)) has set up a new drone, Tencent App Center, which specializes in all kinds of civilian research on drones. It cooperates with (NOAA) of the US Oceanic and Atmospheric Administration (NOAA) to use drones for scientific research such as weather forecasting, global warming and glacier melting. When the forest fire raged in 2007, NASA used the Ihana (Ikhana) drone, which is slightly smaller than the global eagle, with a wingspan of 20 meters and a cruising altitude of 12000 meters, to assess the severity of the fire and estimate the damage. The Ihana UAV is a modification of the military UAV Predator, which is used for civilian and environmental monitoring purposes. 

The United States has increasingly used drones in a variety of industries. NASA has transformed large high-altitude drones originally used by the military on the battlefield for monitoring and research on hurricanes and tropical storms. Drones are also widely used in land management and wildlife monitoring in the United States. 

Other federal agencies and private agencies in the United States are also using smaller drones to do everything from monitoring bird populations in Colorado to monitoring volcanoes in Hawaii. Scientists from the Federal Geological Survey ((USGS)) launched a Raven drone from Upper Red Rock Lake in Montana, carrying a thermal imaging camera that will help scientists search for hot springs below the lake. With a wingspan of 1.2m and a battery-powered motor, the Raven UAV can stay in the air for up to 90 minutes and can fly at an altitude of 305m at a cost of just $3000. 

The RQ-16 Desert Spider Bee is a vertical take-off and landing drone made by Honeywell (Honeywell) in the United States, which can usually be moved by an operator with a proprietary backpack. It also served as a monitoring mission during the 2011 Fukushima nuclear power plant incident in Japan. 

Considering the huge civilian market potential of drones, Obama signed the Federal Aviation Administration (FAA) Modernization and Reform Act 2012, the core of which is to open airspace to civilian drones to promote the development and application of UAV technology, with a deadline of the end of 2015. The bill requires the Federal Aviation Administration ((FAA)) to change its rules to allow local governments, private companies and ordinary people to use small drones. At present, an American AAI company's "Shadow 200B" (Shadow200B) civil UAV has obtained a test airworthiness certificate granted by the Federal Aviation Administration ((FAA)), which enables it to be used in a general aviation facility airport in southeastern Arizona. 

Israel. 

Israel is one of the most advanced countries in the world in the design and manufacture of drones. Israel has set up a test committee on civilian drones and their working modes, and Elbit Systems has taken the lead in completing the required procedures, and its Helms 450 UAV received a civilian certificate in May 2007. In 2008, the medium-to-high-altitude long-flight time Heron drone of Marat, a subsidiary of the Israeli aircraft industry company, obtained the certificate to carry out non-military missions in Israeli airspace, and since then, the relevant departments have cooperated to carry out test flights for a variety of civilian missions. 

Russia. 

A-03Nart is a multi-purpose UAV developed by Russian company AntigradAir. Carry out such as the prevention of catastrophic natural weather events, the formation of artificial rainfall in arid areas, monitoring roads, water and land surfaces, weather and environmental conditions, etc. The geometry and performance parameters of the aircraft are as follows: total length 5.2m, wingspan 9.0m, maximum take-off weight 1100kg, driving force 2 PD-317 propeller engines, maximum speed 450km Universe, endurance time 50 hours, maximum altitude 8000m, remote control, including automatic system monitoring and meteorological bureau monitoring station, lift off through fixed launcher or truck ejection rack. A multi-function information transmission system that can be loaded with MITS. It can also be widely used in law enforcement according to demand. 

Europe. 

Europe formulated and immediately raised funds to implement the "Roadmap for the Development of Civil UAV" in 2006, with the first phase spanning six years. The "Roadmap" predicts that the market for civilian drones has developed rapidly since 2010, breaking the 100 million euro mark and rising to 270 million euros by 2015, of which Earth observation accounts for about 3.7% of the market, communications and maritime surveillance each account for 13% of the market, forest fire prevention and fire fighting market share is about 12%, and law enforcement accounts for 3%. The EU intends to set up a pan-European civil UAV coordination organization, which is mainly responsible for experimental research on market assessment, technical surveillance, airspace control, airworthiness and safety, standard-setting, general interface, cost control and so on. In order to solve the most critical problems of air safety and airworthiness. The Netherlands has begun to study and test the "detection and avoidance" system in non-isolated airspace. 

Japan. 

At present, Japan has 2346 registered agricultural unmanned helicopters and 14163 operators, making it the largest country in the world for spraying agricultural drones.
