Drones work by receiving radio signals from a connected controller that is paired with a unique identifier to make sure that each controller only works with a particular drone. This radio signal commands the drone to perform actions that the user wants, while the drone sends data related to position, speed, tilt, and any audiovisual feed to the controller via a bi-directional data link.
The drone utilizes several on-board sensors and chips to determine these variables which are parsed by the controller and displayed to the user via a connected mobile device or on the screen of the controller.
The controller may use one of a variety of standard communication technologies for sharing data with the drone, which will be discussed later in the article.
We shall also introduce the Snaptain SP700 beginners’ drone, with an overview of its features and how it compares to other drones in its category.
Most drone controllers utilize radio technology for communicating with a drone. The earliest drones only had the capacity for one-way communication from the controller to the drone. But with advancements in capabilities, most drones now have a bi-directional communication capability that lets the controller receive GPS, speed and other related data from the drone as well.
Most controllers utilize a Wi-Fi connection along the 2.4 GHz spectrum which allows for nearby mobile devices to connect to the controller as well for receiving video and other data from the drone.
Remotely Controlled Drones
For controlling a drone remotely, a mobile signal connection (RF Frequency) can be used to control the drone by bouncing signals off signal towers in the vicinity. This technology is yet only available on select consumer models and is mostly used by the military. An even more advanced technology for the control of drones is by utilizing a satellite uplink, as is used in most military grade UAV’s.
Sensors Used for Controlling Drones
The accelerometer and the gyroscope form the core part of the drone that allows it to navigate and operate properly.
The accelerometer senses and measures the acceleration forces along each axis as it flies. It also determines the angle of the tilt during flight as well as on the ground.
During the flight, each of the axis experiences a value of G, where 1 means that the drone is at rest or hovering with reference to the standard gravitational force of the Earth being taken as 1. This reading is then passed through algorithms to determine the correct position/tilt of the drone.
The accelerometer also provides values for the linear acceleration of the drone during flight and its vertical trajectory. This data is used to determine the velocity, direction, and rate of change of altitude for the drone during flight.
The gyroscope determines the angular velocity and the rate of change of angle in pitch, roll, and way at each of the three axes. This information is used to stabilize the drone and prevent wobbling during flight. The data is directly used to alter the speed of the motors dynamically to ensure stability along each axis. It also allows the rotation of the drone when the user is controlling the craft.
The Snaptain SP700 is a beginner drone for those starting out in their exploration of drone technology. The unique features it offers places it at a mid-level range in terms of capabilities as compared to the price.
A great aspect of the drone is that it utilizes 5G WiFi transmission that enables stronger signals allowing for about 500 meters of control distance or around 1680 ft which is a lot more than other drones in this specs range. This technology also allows for better GPS positioning and Return-to-Home function.
Better Control and Maneuverability
The faster communication capability between the drone and controller allow for faster sharing of the video or image feed to the partner app and greater maneuverability and flight control as the drone receives commands from the controller faster.
The drone carries a 1800mAh battery allowing for around 18 minutes of continuous flight time. The drone utilizes a 2K camera and has intuitive Follow-Me capabilities.
Based on its specs and on-board technology, the Snaptain SP700 variant is an excellent choice for beginners allowing the user to explore some advanced capabilities in a good price range. With the variety of technological advancements appearing in the market every year, be sure to keep your eyes open for the next leap in drone technology.
