Indian Startup Launches First OptoSAR Satellite, Marking Private Space Milestone
New Delhi — Bengaluru-based startup GalaxEye on Sunday launched India’s first OptoSAR satellite, a 190-kg spacecraft designed for all-weather Earth observation, marking the country’s largest privately built satellite and a significant step in expanding India’s commercial space capabilities.
The satellite, developed under GalaxEye’s Mission Drishti program, was launched aboard SpaceX Falcon 9 from Vandenberg Space Force Base, carrying what industry officials described as one of India’s most advanced private Earth-imaging systems into orbit.
Prime Minister Narendra Modi welcomed the launch, calling it “a major achievement” in India’s space journey and praising it as evidence of innovation-driven nation-building.“The successful launch of the world’s first OptoSAR satellite and the largest privately built satellite in India is a testament to our youth’s passion for innovation and nation-building,” Modi said in a social media post.
The spacecraft combines optical imaging with synthetic aperture radar (SAR), allowing it to capture high-resolution images in daylight and clear conditions while also using radar pulses to observe terrain through clouds, smoke and darkness.
This hybrid system is expected to improve reliability in Earth observation by enabling continuous monitoring regardless of weather or time of day, making it valuable for defense, border monitoring, agriculture, disaster management and infrastructure planning.
The satellite is expected to transmit its first observation data within the next few weeks, according to the company.Lt. Gen. A.K. Bhatt (Retd.), director general of the Indian Space Association, said the launch sets “a new benchmark for India’s private space sector.”
“It serves as a definitive proof-of-concept for India’s private space sector reforms and signals a transition from small-scale testing to sovereign, all-weather surveillance capabilities critical for national security and disaster response,” he said.
India has been working to expand private participation in its space economy as part of a broader strategy to raise its current 2% share of the estimated $450 billion global space market to nearly 8% by 2033.The country had more than 300 active space startups in 2025 across launch systems, satellite manufacturing, communications, propulsion, electronics and data analytics, reflecting rapid growth since the liberalization of the sector.
Bhatt said GalaxEye had joined a small group of global players capable of integrating optical and SAR systems on a single platform.“What stands out is not just the technology, but its broader impact on how downstream applications will increasingly define value in the space economy, particularly in Earth observation, where timely, decision-grade insights are critical,” he said.
The launch underscores India’s efforts to shift from government-led missions to a broader ecosystem where private companies play a central role in strategic and commercial space operations.
