Drones with automatic return independently fly back “home.” By this term, suppliers mean the point from which the UAV last took off, which may not coincide with the operator’s current location. To ensure equipment safety, Global Mark recommends purchasing an Autel drone with auto-return — one of the most advanced technologies on the market.
How the Auto-Return Function Works
Autel Robotics has defined three scenarios when the automatic return function is triggered:
- battery charge drops to a critical level;
- connection with the pilot is lost;
- at any time when the operator activates auto-return in the Autel app.
The app also allows manual adjustment of this mode’s parameters. Based on flight experience, UAV operators can change return altitude, flight speed to the starting point, and more.
Using GPS and GLONASS satellite positioning systems or GNSS-free navigation (in newer models), an Autel drone with auto-return precisely locates its starting point. With binocular cameras and ultrasonic sensors, it creates a detailed depth map, determines the plane and angle of the landing site.
Advantages of Autel Quadcopters for Missions
Autel drones are used for reconnaissance, observation, artillery fire adjustment, and other tasks. During flights, operators must not only gather data but also preserve equipment. Using a professional Autel quadcopter with return functionality increases UAV survivability in demanding conditions.
Before auto-return, the drone sends a warning to the operator. It then climbs to the preset altitude and heads to the starting point. This function makes drone control easier:
- Automatic activation of auto-return. The operator does not need to constantly monitor battery levels. The quadcopter calculates the point of no return considering distance traveled and headwinds.
- Flight safety and intelligent obstacle avoidance. The drone recognizes branches, power lines, and structures in real time. If new obstacles appear, it avoids them and prevents collisions.
- Precise landing. The quadcopter scans the landing surface during takeoff and compares it with current imagery when returning. With cameras, sensors, and AI integration, it lands exactly at the takeoff point.
- High survivability in complex conditions. Autel drones automatically activate auto-return even under strong electronic warfare interference. GPS is not mandatory — they generate accurate terrain maps and identify the starting point using visual markers.
If auto-return drones are required, advanced models from the Autel EVO Max series are available. They feature powerful optics and multiple intelligent functions.
Technical Specifications of Autel Models
As an official supplier of Autel drones, Global Mark offers the latest models. Currently, two are available for mission use, differing in camera setups for specific purposes:
- EVO Max 4T — suitable for high-precision reconnaissance and long-range observation. Equipped with a 48 MP zoom camera, 10x optical zoom, and 160x hybrid zoom.
- EVO Max 4N — designed for operations in extremely low-light conditions. Instead of a zoom camera, it features a Starlight night vision camera (2.3 MP) that delivers clear images in near-total darkness.
Both drones share the same platform and flight characteristics. Autel quadcopters include return-to-home, 720° obstacle avoidance, 3D mapping, a laser rangefinder for coordinates up to 1200 m, and AI algorithms for recognizing people and vehicles.
