What are Drones?
Actually the word Drone
is discouraged in the science and technology circles. The correct word should be Unmanned Aerial Vehicles
or UAVs. The word Drone came into being as the initial UAVs had a bee like structure with the buzzing rotors.
Initially they were used by government and military organisations for their use in warfare. But now they are marketed for kids, teenagers, photographers and nature lovers among others. They come in different sizes and shapes. History of Drones
The very first reference to a drone, or a drone like structure can be traced to 1849. It was not exactly in the form of modern day UAVs. Austria attacked Italy with unmanned balloons loaded with explosives. The actual unmanned aircraft was used during the World War I. How do they work?
As for construction, drones use lighter components in their construction. This ensures lower weight and good options in manoeuvrability. They are also equipped with GPS, laser guided missiles and infra red cameras. These constituents depend on the purpose for which the drone has been built.
They are made in different sizes depending on the usage planned. There are drones that can be flown by hand and then there are those which need runways ( not of the type we see in airports, though).
The drone has two basic components - the Drone itself and the control system. The drones are controlled either through a full fledged control centre or through a remote if it is a smaller one.
The actual technology used in drones is not uniform across all of them. The material, type of construction and control depends on the usage area that the drone has been developed for. Computer languages and algorithms used in Drones
The language needed to build a drone would be dependent on the type of construction and the usage being employed. Normally it depends on the hardware used. For controlling the drone, you can use any programme language as you would do with an application. Normally C++ based languages are used. Artificial intelligence in drones
Well, the AI usage is confined to the government and military purposes. As long as the commercial usage is concerned (it should not be forgotten that commercial drones are not permitted - at least in India). Drones in India
As for the usage of drones by India, the first ever instance should be in 1999 during Kargil Conflict. When manned aircraft caused casualties as it proved to be inefficient when it came to handling the inaccessible terrain of Kargil region, Indian Air Force used IAI Heron and searcher drones which could help get better information about the line of control. After the success of these drones, India has upped its purchase and development drones into its fleet. India currently has a huge fleet of drones Harpy and Harop UAVs from Israel Aerospace Industries. It also has IAI Heron and searcher drones.
There are a few indigenous drones developed by DRDSome of them include
- DRDO Lakshya: This is used for discreet reconnasance and target acquisition.
- DRDO Lakshya:This drone is used for intelligence gathering in the enemy territories. The drone is also used in reconnaisance and surveilance. The drone is currently going through the trial runs.
- DRDO Aura: It is a stealth drone that can missiles and bombs. It is still in development and likely to be tested in.
- DRDO Rustom:It is a Medium-Altitude Long-Endurance (MALE) system. It can be used both for reconnaisance and combat. They have been planned for replacing the Israel Heron drones.
There are also civilian drones being developed in India. Amazon has been into Prime Air delivery systems.
