📖 TERMS ON THIS PAGE5terms
Automatic Takeoff/Landing is a UAV capability that enables a drone to initiate and complete takeoff and landing sequences autonomously using onboard sensors and control software.
Capable of performing tasks or missions without direct human control, using onboard systems to make decisions and execute actions.
Electro-optical/infrared sensor combining daylight cameras and thermal imagers for real-time target detection, tracking, and identification in military drones.
Synthetic Aperture Radar (SAR) and Ground Moving Target Indicator (GMTI) radar are airborne radar systems used to detect, track, and image moving or stationary targets on the ground, regardless of weather or lighting conditions.
A communication link between a drone and its control station via satellite relay, enabling beyond-line-of-sight (BLOS) operations.
