Drones were at the mercy of the wind for a very long period. The days of a drone taking off just because a wind gust hit it are over. Nowadays, even some of the most affordable drones on the market can use stats hover.
Drones can indeed hover in one place. Many drones come with sensors and GPS equipment, enabling them to hover steadily in the workplace. Occasionally, some drones approach so still that it appears strange to sight.
This function is extremely helpful for jobs like aerial photography and filming, as well as surveillance and inspections. The article will highlight how a drone can hover in one spot and the possible reasons behind the stationary position of drones.
How Does A Drone Remain Stationary?
A drone can hover in one place for a variety of reasons. Technology has advanced in many ways, including how the onboard computers respond to external forces, how the arms and propellers are socially constructed, and perhaps most importantly, how GPS location is determined.
The following sections will explain in detail the process behind a drone maintaining its stationary position:
- The Inbuilt Processor And Sensors
The drone onboard computers’ capacity to account for external influences is one of the most generally beneficial developments in drone technology. The drone’s onboard computer will reduce the power to the motors on the left side to balance out the force applied if it detects the drone being pushed upward and to the right by a gust of wind.
Without the onboard computer commanding the drone to reduce power to specific motors, the drone would be propelled higher and be unable to maintain its position in the air. The same holds for air masses that push downward.
The drone’s motors will spin faster if a downward force is provided while it hovers, bringing about an equilibrium in the fight and allowing it to stay in place. This technology has advanced significantly, and it contributes considerably to the feasibility of hovering.
- Physical Appearance
The drone’s physical structure is minor in its ability to hover in one place. It is no secret that drones have evolved to become more compact, quieter, and more intelligent. Moreover, drones’ uniform weight distribution is one of the factors in their ability to hover.
In the past, many drones were constructed with uneven weight distribution.

These days, the drone is frequently perfectly balanced. In certain instances, the camera is put on the front, and the battery is arranged from middle to rear, as with the DJI Mavic series. It gives the drone good balance.
- GPS Navigational Aid
GPS navigation is one innovation that drones have lacked for most of their history. A GPS provides information to their internal onboard computers. Without this, the drone could not identify where it must remain fixed to hover in one place.
In some situations, the GPS unit is sufficiently precise that the drone can be used for aerial surveys, producing an aerial map with a worldwide positioning error of less than one centimeter.
Why Would You Need A Drone To Remain Stationary?
There are several reasons for a drone to remain stationary. The following sections will discover some of these reasons in detail.
- Disconnection
The drone may take off when the pilot loses control due to a broken connection between the remote controller and the aircraft. It frequently occurs if a mountain, structure, or tree blocks the drone pilot’s line of sight to it.
The drone would previously start flying in the last direction the pilot commanded it. As a result, drones frequently enter restricted airspace, collide with private property, or strike a person in the worst-case scenario.
However, with the ability of drones to hover in a stationary position, a drone operator can perform three actions to regain the lost connection with the drone. The most common option amongst these three is to hover. This way, the pilot can change the position until the drone is visible again and the connection is regained.
- Drone Mapping
The drone must hover in one place to undertake drone mapping. It is because an automatic flight is typically required for drone mapping. The standard automated flight contains the following phases:
- The drone immediately ascends to a predetermined altitude
- The drone briefly pauses to determine its location to the automatic flight plan
- The drone travels the path
- The drone briefly hovers over its waypoints
- The drone lands
Without the capacity to hover, the drone may lose track of its location, be reactive to the predetermined flight plan, or carry out the trip entirely at the wrong place at worst.
- Landing
Landing is a necessary component of flight, and it’s frequently automated. The autonomous landing procedure includes hovering in one place before descending gradually. As its sensors search for an appropriate location to land, the drone hovers about two feet above the surface.
The drone’s sensors would determine that the terrain underneath it is safe to land, but if it couldn’t hover in position, it might wander and land on an uneven surface. Therefore, hovering is essential for a secure landing. Fortunately, new drones can hover and maintain their position to an almost uncanny degree.
- Turbulence
Drones that hover in one place are frequently used to counteract the impact of wind on the drone. The drone must frequently remain still while filming a drone video, such as a hyper-lapse, overhead view, or aerial traffic study. For this reason, it needs to hover in one place alone.
The drone could be controlled to stay in one place with some skill and no wind, but it would be pretty challenging. The drone would be pushed if there was a slight wind gust. The drone’s ability to hover in one place allows the pilot to relax and not worry about a wind gust.
Flying in solid winds is unsafe, but strong winds are common while flying over a beach. It is largely unavoidable, and since the drone can still hover in one place, gusts of wind present no issue.
Conclusion
Thanks to cutting-edge technology, including onboard processors and sensors, GPS tracking, and balanced physical structure, drones can hover in one place.
This drone feature is essential for jobs like aerial photography, drone mapping, secure landings, and battling wind turbulence. By enabling the operator to maintain control and avert any mishaps, the ability to hover in one spot also adds to the safety and security of drone flight.
