All type of drones, except toy drones without a camera, have to be registered with the Civil Aviation Authority. The regulations cover nearly all forms of drone use from commercial and recreational to scientific. [51] Drone users who failed to register their drones by 9 January 2018 could face up to five years in jail or a 100,000 baht (US$3100 ...
The earliest use of sunlight for communication purposes is attributed to ancient Greeks and Romans who used polished shields to send signals by reflecting sunlight during battles. [4] In 1810, Carl Friedrich Gauss invented the heliograph which uses a pair of mirrors to direct a controlled beam of sunlight to a distant station.

The flight of the drone can be controlled entirely manually from the control station (at a distance of up to 50 km) or be fully autonomous, performed according to a previously programmed route with the possibility of manual correction during the flight. The flight is extremely quiet due to the fact that the drone glides for

As of 2021, quadcopter drones exemplify the widespread popularity of hobby radio-controlled aircraft and toys, but the use of UAVs in commercial and general aviation is limited by a lack of autonomy [clarification needed] and by new regulatory environments which require line-of-sight contact with the pilot.
Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors.. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the radar.
