What are the remote control models and military drones based on? Is it a radio?

Very detailed information, I hope it will help you. \x0d\ 1。 Advantages of Aerial Survey UAV \x0d\ Compared with traditional surveying and mapping, UAV aerial survey system has the advantages of low cost, flexibility, diverse loads, wide application, simple operation, safety and reliability, and plays an increasingly important role in modern surveying and mapping industry. \x0d\ II。 The working principle of aerial survey UAV \x0d\ is controlled by radio remote control equipment or airborne computer program control system, and a small digital camera (or scanner) is used as airborne remote sensing equipment \x0d\ III. Aerial survey UAV flight platform \x0d\ 1. The system consists of x0d flight platform, flight navigation and control system and ground monitoring system. \x0d\2。 The performance index of the flight platform requires \x0d\a) the mission load should be greater than 2kg\x0d\b) the size of the mission module should be greater than 625px (length) ×500px (width) ×625px (height); \x0d\c) Cruise speed 60-160 km/h; \x0d\d) The upper service limit is 3000m above sea level; \x0d\e) battery life is longer than1.5h; ; \x0d\f) Wind resistance level is greater than level 4. \x0d\ IV。 Flight control system of aerial survey UAV \x0d\ 1. System composition \x0d\ Flight control system is used for navigation, positioning and autonomous flight control of UAV, and consists of flight control board, inertial navigation system, GPS receiver, air pressure sensor, airspeed sensor, speed sensor and other components \x0d\2. Performance requirements of flight control system \ x0d. \x0d\b) The weight should be less than 2kg；; \x0d\c) Flight attitude control stability: roll angle is less than 3, pitch angle is less than 3, heading angle is less than 3° \ x0d \ d) Track control accuracy: yaw distance is less than 20m, altitude difference is less than 20m, and track curvature is less than 5. \ x0d \ v. Ground monitoring system of aerial survey UAV \x0d\ 1. The system consists of a wireless remote controller, a monitoring computer system, a ground power supply system \x0d\ monitoring software. \x0d\2。 Flight control system performance index requirements \x0d\a) The host computer of the monitoring station should be a reinforced notebook computer or computer and electronic equipment with the same performance; \x0d\b) The hardware of the ground monitoring system shall be designed in an integrated way, which is easy to disassemble, carry and carry; \x0d\c) Monitoring data can be displayed in both graphic and digital forms, and the display should be comprehensive, intuitive and practical; \x0d\d) The number of channels of the radio remote controller should be more than 8 to meet the use requirements; \x0d\e) The monitoring computer shall meet certain waterproof and dustproof performance requirements and can work normally in harsh outdoor environment; \x0d\f) The main frequency and memory of the monitoring computer shall meet the requirements of the monitoring software for the computer system; \x0d\g) The power supply system shall ensure that the continuous working time of the ground monitoring system is more than 5 hours. \x0d\ VI。 Take-off and landing mode of aerial survey UAV \x0d\ 1. Take-off mode: \x0d\ taxi take-off \x0d\ Advantages: no catapult is needed. \x0d\ Disadvantages: Limited space. \x0d\ catapult takeoff \x0d\ advantages: there is no space restriction. \x0d\ Disadvantages: Need to buy slingshots. \x0d\2。 Landing mode: \x0d\ taxi recovery \x0d\ Advantages: parachute recovery is not required. \x0d\ Disadvantages: Limited space, not as safe as skydiving. \x0d\ parachute recovery \x0d\ Advantages: safe and reliable, less limited by the site. Disadvantages: Parachute \x0d\ flight control system is required. \x0d\ VII。 Safety requirements for aerial survey UAV \x0d\ 1 UAV shall be equipped with parachute dropping equipment. When the UAV encounters sudden failure, the parachute can slow down the descent speed, avoid or reduce the impact and damage to the ground target, and reduce the damage to the flight platform and airborne equipment; \x0d\2。 The designed flying height should be higher than the shooting area and the highest point of the air route 100m or more; \x0d\3。 The total range of the designed route should be less than the farthest range that the drone can reach; \x0d\4。 The distance from military and commercial airports must be above 10km; \x0d\5。 The landing site is relatively flat and has good visibility; \x0d\6。 Away from densely populated areas, there can be no high-voltage lines, tall buildings and important facilities within a radius of 200m; \x0d\7。 There should be no obvious prominent rocks, ridges, stumps, ponds, ditches, etc. On the ground of the landing site; \x0d\8。 There should be no interference sources such as radar station, microwave relay and wireless communication in use nearby. In case of uncertainty, the frequency and intensity of the signal should be tested. If it interferes with the system equipment, it is necessary to change the landing site; \x0d\9。 If the UAV takes off and lands by taxiing, the taxiing road surface conditions shall meet its performance requirements. \x0d\ VIII。 Aerial survey UAV photographic equipment \x0d\ At present, the payload of fixed-wing UAV on the market is generally less than 5Kg. Therefore, this kind of UAV can not carry the advanced aerial camera of 100 kg commonly used by manned aircraft. At present, most of the high-end SLR cameras are used, and the image frame is above 3K×4K. \x0d\ IX。 Reference for selection of aerial survey unmanned aerial vehicle \x0d\ Because the complexity of aerial survey unmanned aerial vehicle is higher than that of general aircraft model, all equipment needs to have good compatibility, so it is difficult to assemble and debug the equipment alone, and there are certain risks in compatibility between the equipment, so buying a complete set of equipment is the best choice. It is suggested to choose Kunming Jinying Aerial Survey UAV Company, mainly due to the following factors. This company specializes in the design, production, sales, aerial survey and aerial photography services of aerial survey UAV equipment, and is the top design and manufacturing service provider of aerial survey and aerial photography UAV in China. It has the characteristics of good effect, high precision, strong technology, high speed and high level, and is in a leading position in the industry. It has successively gone to Africa and other foreign countries with harsh natural conditions and lack of spare parts and tools, and successfully completed the aerial survey task! It has the only professional training ground for model airplanes and drones in Yunnan Province, including senior coach of Yunnan Model Aircraft Team, professional training for drones, air force air traffic control policy propagandist and formalities handler. As long as it does not affect civil aviation, military secrets and flying out of national borders, aviation can be approved and supported.
