Drone Glossary

 

A)

Accelerometer: Device that measures the acceleration forces in a certain direction and helpful in maintaining the Drones orientation. These devices are used to stabilize quadcopters.

Aerial Photography: the hobby of capturing images and video while in the air with a camera mounted to your drone.

AGL: Altitude above ground level

Altitude Hold function: Allows pilot to focus on the camera while the drone hovers steadily in air by itself at a set height. A Onboard barometer is needed to allow Altitude Hold.

Autopilot: A capability of a drone to conduct a flight without real-time human control. For example, following pre-set GPS coordinates.

Axis: One plane of potential flight. Most quadcopters have at least 4 axis controls, with 6+ being preferred.

B)

Barometric Pressure Sensor: This device used barometric readings to determine the altitude of the aircraft. It can help drones to be able
to calculate their height above the ground, along with using combinations of other sensors. ( Enables Altitude Hold feature )

Bind: This is the process of making the controller (Transmitter) communicate with the quadcopter or the drone.

BNF: Bind N Fly. The unit is ready to bind to your  transmitter and fly.

Brushless Motor: These motors have permanent magnets that rotate around a fixed armature, which eliminates any problems that could be associated with connecting current regarding a moving part. The brushless motors are much more efficient and hardy than brushed motors.

Build: A unit that is build at home as opposed to one that is store bought.

BVLOS: Beyond visual line of sight.

C)

Camera gimbal: This is actually the holder of the camera used on drones. It can tilt and swerve, thanks to the servos that power it. The gimbal is strong enough to support even large DSLR cameras.

Controller: The handheld device that is used by the drone pilot that is used to control the drone and the quadcopter. Controllers are also called transmitters. Here is a picture of a higher end controller.

D)

Drone: UAV capable of autonomous flight.

E)

F)

FAA : Federal Aviation Administration A United States Department of Transportation Agency, with the authority to regulate and oversee all aspects of American civil aviation.

First Person View: Also known as FPV, a system in which the drone operator views the camera footage from the drone in real-time. The video stream is either viewed through a pair of special goggles, or to a device like a tablet or smartphone.

Firmware: The sketch or software loaded into the microprocessor based products’ non-volatile memory. The reason it is referred to as firmware is because it remains in non-volatile memory state even when power is removed. Therefore, it is non-volatile. In the autopilots case, it is an application (App for smart phone users) or program that determines how and what the auto pilot does

FPV: Acronym for “First Person View.” This is also known as “Remote Person View” (RPV). The FPV is situated on a camera (such as GoPro) and is mounted on the Quadcoptor which allows the operator view exactly what the aerial vehicle is viewing in real time.

Flight Control System: This is a network of controls that is interconnected and allows the pilot to fly the quadcopter or any other multi-rotor airborne vehicle.

Fly Away: Unintended flight outside of operational boundaries (altitude/airspeed/lateral) as the result of a failure of the control element or onboard systems, or both.

Fly-Away Protection System: A system that will return the UAV safely to the surface, or keep it within the intended operational area, when the link between the pilot and the UAV is lost.

G)

Gimbal: This is a specialized mount for a camera, giving it the ability to swerve and tilt by utilizing servos. This gives the camera the
capability of staying in one position, regardless of the movement of the drone. This allows for a very smooth and stabilized and smooth
looking image.

GPS: Global Positioning System that is used to track the position of an object in relation to the global spatial plane, track movement, or cause an airborne vehicle such as a quadcoptor to hold position, such as the advanced Dji Phantom.

Ground Control Station: GCS. This software runs on the ground on a computer. It receives telemetry information via an airborne UAV. It displays its status and progress. This frequently include sensor and video data. It also can be used for transmitting in-flight commands up to the UAV in the air.

Gyroscope: A gyroscope or gyro, measures the rate of rotation of the UAV and helps keep the craft balanced correctly with respect to yaw, pitch and roll. Helps to maintain the orientation of the quadcopter while in flight. In most cases, quadcopters use a triple-axis gyroscope.

H)

Hexicopter: A multi-rotor aircraft having six rotors in which the beauty and advantage of the hexicopter is that it can lose any single engine and still maintain control to land.

Hobby Grade: Better than toy grade, these quads can offer a good reliability and operation at a reasonable price tag.

Headless Mode: regardless of the orientation of the craft, the way the front of the craft is pointed, it will follow your stick movements.

I)

IMU: The Inertial Measurement Unit is a controller which combines an accelerometer and a gyro, with the purpose of helping with the orientation and stabilization of a quad.

Inertial Navigation System: INS. This is a means of calculating position that is based on the initial GPS reading. This is followed by speed and motion sensor readings that use dead reckoning. This is useful when the GPS has lots its signal temporarily or is not available.

IOC:  intelligent orientation control – Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Intelligent Orientation Control (IOC), wherever the nose points,the forward direction has nothing to do with nose direction:

L)

Line of Sight: Also known as LOS, refers to being able to see your drone from your operating position with your naked eye. Your drone should always be within your line of sight.

LiPo: Short for Lithium Polymer, LiPo is the type of battery favored by most drone manufacturers due to its low weight and maximized charge capacity and power. Although LiPos are safe, be aware overcharging the battery or breaking the flexible polymer case could result in fire.

Lithium Polymer battery: LiPo or LiPoly. The Lithium Ion battery (Li Ion) is a variant. Lighter weight and more power is offered by this battery chemistry compared to NiCad and NiMh batteries.

M)

Mobius Camera: Popular lightweight camera model which can shoot video in HD and take intervalometer photos. It was developed mainly to be used with RC drones.

Mod: modification: Drone addicts modify their machines to integrate new functions or cool features. These changes are usually called mods.
