It can be defined as a pastime or may be a source of income for some people by capturing video and images in the air with a camera mounted on the unmanned aircraft or drone.

AGL

Altitude Above Ground Level (AGL) can be described as the height measured with respect to the underlying ground surface.

Altitude Hold function

This function permits the drone pilot to keep the focus on the camera at the same time when the drone hovers steadily in skill by itself at a certain height. An Onboard barometer is required to permit the Altitude Hold.

ARF

Also known as, almost ready to fly feature. This describes that while purchasing a Drone or Quadcopter what all components come along with it. ARF units might not include a transmitter, therefore it needs to be assembled.

Autopilot

It can be explained as the ability of a drone to carry out a flight without any real-time control by a human. For instance following pre-set GPS coordinates.

It frequently comprises of video data and sensor. It is also used in the situations of transmitting in-flight instructions up to the unmanned vehicle in the air.

Gyroscope

This drone terminology gyroscope or gyro is responsible for keeping the aircraft balanced in accordance with a pitch , roll, and yaw to maintain the orientation of the copter during the flight, it is also used to measures the rate of rotation of the drone. In most of the situations, copters employ a triple-axis gyroscope.
