Independent flight first originated with fixed-wing drones. After the rise of consumer drones, more and more drone manufacturers and flight control research and development organizations have continued to investigate autonomous flight. RTK As the technology has matured, autonomous flight technology has made great strides. More and more drones are now using autonomous flight technology.
Plant protection drones prefer to fly independently compared to more complex remote control operations. This is closely related to the application scenarios and training costs of plant protection drones, and can be said to be the inevitable choice of the market.
Why the need for independent flight?
Consumer drone remote stick operation emphasizes feel, fun and driving **, which is quite different from plant protection drone flight. Plant protection drones generally fly primarily on planned routes. If the pilot is unable to accurately control the flight status, it is easy to spray unevenly, which may lead to large-scale yield reduction and incalculable economic losses to farmers.
In order to avoid this situation, plant protection UAVs have high requirements for autonomous flight on established routes.
On the other hand, plant protection personnel are different from model airplane players. The drone is a tool for their work, not a hobby. What most plant protection practitioners need from plant protection drones is quick startup and simple operation. This also has certain requirements for autonomous flight of plant protection aircraft.
For plant protection teams, the training cycle to operate a plant protection drone using a remote control is long and the operation is relatively complex. Flight defense teams and farmers alike need to spend more time and money. A plant protection drone that can fly independently can greatly save costs and increase the income of the plant protection team.
How to realize autonomous flight?
Generally, each brand of flight control has its own flight functions. However, if you rely only on the flight control GPS if the module flies independently during operation, the GPS module may be interfered with by the surrounding environment GPS loss of stars, drift, inaccurate positioning of the drone, resulting in inaccurate operation routes.
If the operation route drifts, it is easy to appear heavy spraying, leakage spraying, uneven spraying, route span is too large or flight speed is too fast, resulting in drug damage. The paddy field will show a green or yellow state such as a soccer field, and the unsprayed area will be obvious at a glance, and this operation effect will obviously not be accepted by farmers.
Therefore, in order to realize the independent flight of plant protection UAV, most people will choose to match RTK using RTK technology on the aircraft can achieve centimeter-level accurate positioning, greatly improving the accuracy of the route flight, so that the plant protection operation is more accurate and efficient.
Advantages of RTK technology
The use of RTK plant protection UAV generally has the following advantages:
1. High operational positioning accuracy, safe and reliable data, no accumulation of error (generally within 10 kilometers of the base station, up to centimeter accuracy).
2. The technology of RTK high positioning accuracy can reduce the limitation of aircraft landing sites.
3. traditional GPS planting machine need to flyer, safety officer and ground handling three operators. gps different planting machine, use RTK in the operation process, technology planting machine only need an operator to complete the operation, labor costs down to one-third of the past.
