India has cleared the acquisition of fixed-wing High Altitude Pseudo Satellite (HAPS) platforms to strengthen long-endurance intelligence, surveillance, and reconnaissance capabilities while awaiting deployment of its planned military satellite constellation. Operating in the stratosphere above 65,000 feet, these solar-powered unmanned aircraft can remain airborne for several weeks or months, providing uninterrupted monitoring over strategic regions. Unlike conventional UAVs, HAPS combines satellite-like persistence with aircraft flexibility, supporting electro-optical, infrared, synthetic aperture radar, and signals intelligence payloads. Indigenous programs led by CSIR-NAL and NewSpace Research & Technologies are progressing toward operational systems capable of supporting border security, maritime surveillance, communications relay, and disaster monitoring. The initiative significantly improves India’s ability to maintain continuous situational awareness despite its comparatively limited military satellite coverage.
