capability. It has no moving parts other than the rotors, motors and transmissions, and hence it requires very low maintenance. The use of carbon-fibre has resulted in a light weight of , which makes the Netra very portable. A backpack case allows operators to carry the system to field locations to serve as the base station. It also contains the power supply, military-grade controller, hand-held operator console and the communication systems.


Capabilities

Netra can be launched from a small clearing, and it can fly up to a distance of 2.5 km from its take-off point. The operational altitude of the UAV is 200 m. With an on-board wireless transmitter, it can carry out surveillance in an area of 1.5 km Line of Sight (LOS) at the height of 300 m, for 30 minutes on a single battery charge. It has a high resolution CCD camera with a pan/tilt and zoom to facilitate wider surveillance and can also carry a thermal camera for night operations. The zoom-in camera can identify human activity up to 500 m away, and can send live video feed of objects within a radius of 5 km. The images are sent through a local wireless network to laptops for monitoring. Flight and navigation is independent of user-input, and is controlled by an on-board

navigation, in which the user specifies the location of the target and the UAV automatically flies to that location. A built-in fail-safe allows it to return to base if there is loss of communication with the controller or if the battery is low in power. The UAV cannot yet operate in rain and further research is being done to make it operable in all weather conditions.


Trials

10 prototypes were made during the development stage by DRDO and they were put under tests like the temperature tests (from -10 °C to 55 °C) and high-altitude tests. After the successful trials, the UAV was cleared for production and induction. The development stage has been completed and Ideaforge is responsible for the production. The company has manufacturing capacity of 10 units per month. The base price of the UAV is ₹15-20

Further development

Ideaforge is also working on a more advanced version of Netra, which will have an increased flight time from the present 30-minute per battery charge.
