In a significant breakthrough for disaster response technology, Odisha-based deep tech startup BonV Aero played a key role in aiding the Indian Army’s rescue efforts during the recent landslide in Lachen, Sikkim. The company deployed its advanced ground penetrating radar (GPR) drone system to locate subsurface anomalies without disturbing unstable terrain.
The drone, equipped with real-time imaging systems, GPR sensors, and AI-powered anomaly detection software, was able to scan the debris-covered zone from above. The innovation enabled the detection of two critical locations, at depths of 0.76 metres and 0.015 metres, which were later confirmed as sites containing human remains.
“This system’s ability to detect beneath unstable land and transmit real-time data allows responders to act without risking further casualties,” said BonV Aero CEO Satyabarata Satapathy. The drones provided precise coordinates that helped soldiers navigate the debris effectively, increasing the efficiency and safety of the mission.
The rescue operation followed a series of devastating landslides triggered by intense monsoon rains last month in the Lachen region, about 123 km from Gangtok. The disaster claimed the lives of three soldiers, while six others went missing.
Chief Technology Officer Abinash emphasized the potential impact of this innovation, stating, “With this technology, India can now approach landslide rescue and disaster response with smarter, faster, and safer methods.”
BonV Aero’s swift deployment of its GPR drone within 24 hours of the incident reflects growing collaboration between startups and national agencies in addressing complex challenges in hostile environments.
