The Defence Research and Development Organisation (DRDO) has tested its indigenous High-Altitude Platform System (HAPS). Notably, the flight trial took place on 6 October 2026. The platform climbed to 21 km above mean sea level. Then, it stayed at 20 km for more than 30 minutes before coming back down.
Key Highlights of the Flight Trial
- Maximum altitude: 21 km above mean sea level
- Endurance at 20 km: Over 30 minutes
- Developer: Aerial Delivery Research and Development Establishment (ADRDE), Agra
- Recovery: The team commanded the platform to descend and recovered it successfully.
After the flight, experts analysed the flight data.
What Is a High-Altitude Platform?
A High-Altitude Platform is an aerial system that works in the stratosphere. The stratosphere lies roughly 20 km above the Earth. At this height, weather is calm and there are no regular aircraft. So, such platforms can stay in one area for long periods. In this case, DRDO tested a lighter-than-air system.
Systems On Board
The platform carried an inertial measurement unit (IMU) and a GPS receiver. Also, it had onboard cameras and an altitude-control system. Furthermore, it sent live video and data to a ground control station. Thus, the team could watch and control the flight in real time.
Uses of HAPS
- Long-endurance aerial surveillance of borders
- Communication links in remote areas
- Disaster monitoring and relief support
- Weather and environmental studies
Notably, such platforms cost less than satellites. Also, they can be moved and reused.
Agencies Involved
The Indian Air Force, CEMILAC, DGCA and the Airports Authority of India supported the trial. Later, Defence Minister Rajnath Singh congratulated DRDO and its partners. He linked the success with Aatmanirbhar Bharat in defence.
Why the High-Altitude Platform Matters for UPSC and UKPSC
Notably, defence technology and new platforms are key GS Paper III topics. So, remember the altitude, the duration and the DRDO lab. Also, understand why the stratosphere suits such platforms. For official updates, also visit DRDO. Next, for a related story, read about DRDO’s Kusha missile test.
