The North East Centre for Technology Application and Reach (NECTAR), an autonomous body under the Department of Science and Technology, Government of India, has unveiled an innovative Aerostatic Drone designed for forest surveillance, wildlife monitoring, and border and disaster management. Developed by Airbotix Technologies, this drone represents India’s first of its kind, offering a high-endurance, energy-efficient, and aero-statically stable solution for persistent surveillance. The Aerostatic Drone operates by combining buoyancy and aerodynamics, making it silent and cost-effective compared to traditional tethered drones. With an impressive endurance of over 4 hours, it provides a versatile and low-cost option for continuous aerial surveillance across various applications, including wildlife monitoring, forest surveillance, border security, and disaster response. The drone’s modular design allows integration with any ground vehicle or installation at a designated site. It can be equipped with day and night cameras, as well as additional payloads such as telecommunication relays or anti-drone technology, making it adaptable to different operational needs. The ability to function silently and in low-visibility conditions, using thermal imaging and detection capabilities, significantly enhances its effectiveness in security operations and monitoring. During a live demonstration, officials from various organizations, including the CRPF, expressed interest in using the drone for border surveillance, especially in difficult terrains. Its ability to operate silently and detect unauthorized activities without disturbing the ecosystem makes it a valuable tool for security and conservation efforts. The drone’s potential for disaster management, particularly in remote areas or during emergencies, was also highlighted. It can serve as a temporary communication relay, ensuring connectivity when traditional infrastructure is unavailable. Additionally, its low metal components make it nearly invisible to radar, adding a layer of security for sensitive locations such as military bases and airports.
