Gimbal: A camera mount to the drone. Gives the camera the ability to swivel and pivot free from obstruction and difficulty. The camera can fix on a point while in moving flight, because of the gimbal and produce smooth footage.

GoPro: The leading action video camera system on the market. Robust, high quality cameras, used by a huge variety of sport lovers. From Skiing to diving.

Global Positioning System (GPS): Used for orientation, using triangulated calculations from satellite signals transmitted and received from a desired device. Such as a mobile phone, oil rig or U.A.V. The system can be used to keep the required object stationary relative to the desired measurable metric.

Gyroscope: An instrument used to show your current planar horizon compared to the Earth’s true gravity produce horizon.
