First, choose the model
1. Fixed-wing UAV is characterized by long flight time, high speed and long flight distance, but it often requires higher requirements for the process of take-off and landing. Generally, it needs runway, ejection and other devices, and its aerodynamic shape requires more restrictions on the position and shape of the load.
2. The unmanned helicopter perfectly solves the requirements of the runway, can take off and land directly without the runway, and can take off and land in complex terrain, which many fixed-wing UAVs can’t do. Moreover, it can hover and fly backwards in the air, so the UAV helicopter can carry out more types of tasks. However, it should be noted that the unmanned helicopter is difficult to maintain and debug because of its complex structure, and it also has high requirements for load installation, so the secondary development is difficult.
3. Multi-rotor UAV is a new type of UAV, which has almost no requirements for landing site, relatively simpler structure and operation, more flexible matching load and more accurate positioning, so it is active in various UAV application scenarios. However, it should be noted that the endurance of multi-rotor UAVs is generally not as long as that of fixed-wing and helicopters, and it is oftenthirtyWithin minutes.
Second, select parameters and technical indicators
1. Flight performance
2. cruising range and cruising time
3. Navigation and positioning ability
4. Control Station and Data Link
5. Environmental adaptability
6. Software related indicators
Third, choose services
Fourth, check the quality
