New Delhi: In a strategic leap for indigenous defence technology, the Indian Army has initiated the deployment of solar-powered surveillance drones to strengthen multi-terrain border monitoring and intelligence operations.
This first-of-its-kind UAV (Unmanned Aerial Vehicle) acquisition underscores India’s commitment to sustainable, autonomous, and long-endurance defense solutions, aligned with the Atmanirbhar Bharat initiative and advanced battlefield requirements.
Importance of Solar-Powered Spy Drones
With India’s 7,517 km of international borders spanning diverse terrain from the high Himalayas to arid deserts, maintaining persistent and reliable border surveillance poses operational challenges.
Traditional battery-powered and tethered drones demand frequent landings and logistical support, which are impractical in remote sectors.
The solar-powered UAV, officially named the Medium Altitude Persistent Surveillance System (MAPSS), leverages sunlight as its primary energy source, enabling significantly extended flight endurance and reducing the need for frequent ground support.
This makes it particularly suitable for harsh environments where conventional platforms struggle.
What is Medium Altitude Persistent Surveillance System
Developed by NewSpace Research & Technologies (NRT), a Bengaluru-based defence start-up incubated under the Ministry of Defence’s Innovations for Defence Excellence (iDEX) programme, the MAPSS marks India’s first solar-electric surveillance UAV to be inducted by the armed forces.
What are the Features of Medium Altitude Persistent Surveillance System
Here are the key features of Medium Altitude Persistent Surveillance System;
Solar-Powered and Fully Electric UAV: Reduces dependency on conventional fuel and batteries.
Extended Operational Endurance: Designed for days-long airborne missions. Demonstrations have shown more than 24–27 hours of sustained flight even under partial sunlight.
Multi-Terrain Surveillance: Ideal for mountainous, desert, and communication-denied border zones.
Modular Payloads: Supports ISR (Intelligence, Surveillance & Reconnaissance), ELINT (Electronic Intelligence), and communications relay roles.
Low Detection Profile: Quiet electric motors and minimal thermal signature aid covert operations.
Autonomy in GNSS-Denied Zones: Advanced navigation supports operations even when GPS signals are weak or unavailable.
Contract and Deployment of Solar-Powered Spy Drones
The Indian Army has placed a ₹168 crore contract for this innovative solar UAV system, marking its formal induction into active surveillance and reconnaissance roles.
This procurement is significant not just for its technology, but also for its origination through indigenous R&D and domestic startup engagement, showcasing the success of government programs aimed at strengthening self-reliant defence production.
iDEX and Indigenous Defence Innovation
The MAPSS project is the product of the iDEX initiative, launched in 2018 to bridge the gap between innovators and the Indian armed forces. Through iDEX, over 200 startups have progressed from concept to practical defence deployments. NewSpace Research & Technologies, the developer behind MAPSS, also previously supplied heterogeneous swarm drones to the Army under fast-track acquisition programs.
Experts highlight that this solar UAV acquisition is symbolic of a broader shift toward self-sustaining, low-logistics autonomous systems — particularly relevant for India’s expansive and complex border zones.
How Solar-Powered Spy Drones Fit into India’s Defence Landscape
The Indian Army has accelerated drone deployments in recent years, driven by operational needs post conflicts and emerging threats.
Following Operation Sindoor, which saw increased use of loitering munitions and surveillance systems, the Army signed multiple contracts aggregating hundreds of crores for various UAV systems.
Simultaneously, Indian defence start-ups and private firms are rising to meet these requirements, catalyzing a renaissance in domestic UAV manufacturing aligned with global military modernization trends.
Impact of Solar-Powered Spy Drones
MAPSS is expected to substantially strengthen India’s persistent ISR posture along contested border areas such as:
- Ladakh & Himalayan Frontiers
- Western Desert Frontiers (Rajasthan & Gujarat)
- Connectivity-Poor Regions
Its ability to stay airborne for long durations will assist in real-time threat detection, smuggling interdiction, troop movement tracking, and early warning — all vital for rapid responses along strategic frontiers.
