Bengaluru-based startup Alteon Energy has unveiled “Infinity,” a high-altitude platform station (HAPS) drone designed to remain airborne for over 400 days, effectively functioning as a low-cost pseudo-satellite for India’s strategic needs over the Indian Ocean region. Announced around 5–6 December 2025, the solar-powered platform uses dynamic soaring and wing-mounted turbines to harvest wind energy in the stratosphere, allowing persistent operations between roughly 18 and 30 km altitude above commercial air traffic and weather disturbances. Infinity is projected to support intelligence, surveillance and reconnaissance, as well as 4G/5G connectivity and environmental monitoring, giving India a sovereign capability for continuous maritime domain awareness and border security without dependence on foreign satellite assets. The system aligns with New Delhi’s broader push for indigenous HAPS technologies and complements earlier efforts by CSIR-NAL and private firms in long-endurance stratospheric platforms.
