TL;DR: Bengaluru-based GalaxEye has received a United States patent for the synchronized optical-plus-radar architecture behind its OptoSAR Earth-observation system.

Indian space technology startup GalaxEye said on Tuesday, Sept. 8, that it had secured a U.S. patent for a system that synchronizes optical and radar sensors on satellites, according to CNA's report of the Reuters account. The company described the grant as covering the core invention behind its OptoSAR imaging capability, while Business Standard reported that GalaxEye described itself as the first Indian startup to receive a U.S. patent for satellite imaging technology. The same foundational technology has already been patented in India, Business Standard reported. Chief Executive Suyash Singh said the patented technology enables the company to serve global markets and provide weather-agnostic imaging capabilities across sectors, according to CNA.

The announcement places a startup founded by IIT Madras engineers at the center of competition for commercial Earth-imaging data, according to CNA. GalaxEye has so far raised around $21 million in funding, CNA reported. The company said it is backed by a growing commercial pipeline across domestic and international customers as it prepares to scale toward a planned 30-satellite constellation over the next five years, according to Business Standard. In August, GalaxEye acquired Bengaluru-based spacecraft engineering firm StarOps to strengthen its in-house manufacturing and satellite system capabilities, CNA reported. The Hindu BusinessLine reported that Singh described the StarOps acquisition as part of an effort to build deeper capabilities across the satellite value chain.

What the U.S. patent protects

The U.S. patent covers GalaxEye's core invention for the architecture and system used to align and synchronize optical and microwave sensors for simultaneous, spatially and temporally matched data acquisition, Business Standard reported. CNA described the technology in similar terms as synchronizing optical and radar sensors to capture precisely aligned images of the same location simultaneously. The result, CNA reported, is reliable Earth-observation data even in cloud cover and darkness.

Business Standard reported that securing protection in the United States is strategically significant as GalaxEye develops technology for a global Earth-observation market. The company's intellectual-property strategy focuses on protecting the fundamental architecture of multi-sensor imaging, Business Standard reported. That publication added that the new grant adds a layer of global intellectual-property protection to the technology underlying the company's OptoSAR achievement. The Times of India reported that the patent covers the architecture and system developed to align and synchronize optical and microwave sensors for simultaneous acquisition of spatially and temporally matched data.

Former Indian Space Research Organisation chairman Somanath S. Panicker said the recently granted U.S. patent for the technology behind OptoSAR is a powerful example of the innovation emerging from India's private space ecosystem, Business Standard reported. Panicker added that the development was not only a significant technical innovation but also has strong commercial potential across applications requiring richer, more actionable intelligence, according to the same Business Standard account. The Times of India reported a closely worded assessment from former ISRO chairman S. Somanath, who said the technology's uniqueness lies in synchronizing optical and SAR sensors at the system level to deliver spatially and temporally matched Earth-observation data.

Why combining optical and radar is difficult

GalaxEye is building next-generation Earth-observation capabilities through its proprietary technology for OptoSAR imaging, which combines the strengths of Synthetic Aperture Radar and optical imaging to deliver reliable, all-weather, day-and-night intelligence, Business Standard reported. The Hindu BusinessLine described OptoSAR as combining optical imaging, which provides visual and spectral information, with Synthetic Aperture Radar, which can operate during the day and night and through adverse weather conditions.

The technical problem involves very different sensing physics. At the heart of GalaxEye's technology is a fundamental challenge in Earth observation: optical and SAR sensors operate according to very different physical principles and have traditionally been deployed independently or combined through post-processing, Business Standard reported. The Print explained the distinction for general readers, reporting that optical imaging relies on a camera capturing sunlight reflected from Earth to show vegetation, buildings, roads and waterbodies, but does not function without sunlight or on a cloudy day. In contrast, The Print reported, Synthetic Aperture Radar imaging sends microwave signals toward Earth and measures the signal that returns, with waves that can pass through clouds and operate at night and in cloudy weather.

Even when optical and SAR imagery of the same location is available, the two datasets can be captured at different times, from different viewing geometries and by different platforms, Business Standard reported. That separation creates temporal gaps and spatial misalignment, making it difficult to generate a truly correlated view of Earth, according to the same report. The Times of India gave a parallel description, reporting that even when both types of imagery are available for the same location, they can be captured at different times, from different viewing geometries and by different platforms. The Print reported that images taken separately could differ in time and angle, with features on the ground potentially changing in the interval.

GalaxEye's patented invention addresses this challenge at the system and sensing architecture level, Business Standard reported. The Times of India reported that the company said its patented system addresses the challenge at the sensing architecture level. The Print reported that GalaxEye's solution is to place both imaging technologies on the same spacecraft and design a system to synchronize the imagery, adding that the U.S. patent concerns the architecture used to bring optical and SAR imaging together. The Hindu BusinessLine reported that the patent covers the architecture used to align and synchronize optical and microwave sensors for simultaneous, spatially and temporally matched acquisition.

From laboratory architecture to Mission Drishti

The technology is closely tied to GalaxEye's flagship Mission Drishti, through which the company took its OptoSAR capability to space, Business Standard reported. On May 3, 2026, GalaxEye launched Mission Drishti, its first satellite and the world's first OptoSAR imaging satellite, according to the same report. Drishti combines multispectral imaging and Synthetic Aperture Radar on a single satellite platform, enabling complementary optical and radar observations from the same spacecraft, Business Standard reported.

At approximately 190 kg, the spacecraft was also India's largest privately built Earth-observation satellite at the time of launch, Business Standard reported. The Hindu BusinessLine gave the same approximate mass and the same description of the satellite as India's largest privately built Earth-observation satellite at the time of launch. Business Standard reported that the Government of India also acknowledged and supported the mission as the world's first OptoSAR satellite and highlighted it as a major achievement in India's space journey. The Hindu BusinessLine reported that Mission Drishti helped the company validate its systems in orbit and understand their performance under actual operating conditions. The Times of India reported that the company took the technology to orbit through Mission Drishti, its first satellite, launched on May 3, 2026, but added that the satellite was later declared a failure.

Singh said the company's objective is to build a constellation that provides a more persistent view of Earth rather than simply reaching a particular satellite count, The Hindu BusinessLine reported. He stated, according to that publication: "Our vision is to build a constellation that gives us a much more persistent view of the Earth." GalaxEye plans to deploy two satellites over the next 24 months, followed by full-scale deployment, with capital expenditure also being phased alongside technology and market maturity, The Hindu BusinessLine reported. Business Standard reported that the company expects the planned 30-satellite network to support defense, government and commercial applications across national security, agriculture, infrastructure, insurance, maritime intelligence and disaster management.

Commercial plan after StarOps deal

GalaxEye said the patent strengthens its intellectual-property position as it prepares to build the planned constellation of 30 satellites over the next five years, The Times of India reported. The company expects the network to support defense, government and commercial applications across national security, agriculture, infrastructure, insurance, maritime intelligence and disaster management, according to the statement quoted by that publication. The Hindu BusinessLine reported that the U.S. patent strengthens the company's intellectual-property position as it looks to expand into global Earth-observation markets.

The company is meanwhile building greater control over the satellite manufacturing chain following its acquisition of Bengaluru-based spacecraft engineering company StarOps in August, The Hindu BusinessLine reported. Singh said the StarOps acquisition is part of the effort to build deeper capabilities across the satellite value chain, according to that publication. The move is expected to help the company design, build, test and iterate satellites more efficiently as it moves toward constellation-scale manufacturing, The Hindu BusinessLine reported. CNA similarly reported that the August acquisition was intended to strengthen in-house manufacturing and satellite system capabilities.

GalaxEye is already commercially active across defense, agriculture and forestry and is evaluating global markets where persistent, all-weather, day-and-night observation is required, The Hindu BusinessLine reported. Singh said the company is building capabilities across the satellite value chain, from spacecraft and sensing to the processing and intelligence layers that make the information useful to end users, according to that publication. Business Standard reported that the scale-up is backed by a growing commercial pipeline across domestic and international customers.

Market demand for all-weather imagery

The patent award comes at a time when demand for satellite-based intelligence is growing across security, agriculture, insurance and disaster-response applications, CNA reported. Business Standard listed an expanded set of expected uses for the planned constellation, including defense, government and commercial work across national security, agriculture, infrastructure, insurance, maritime intelligence and disaster management. The Hindu BusinessLine reported that the company believes the OptoSAR combination can support applications ranging from defense and strategic intelligence to agriculture, insurance and disaster response.

The global commercial satellite imaging market, valued at $6.55 billion in 2024, is projected to more than triple to $20.15 billion by 2033, according to research firm SkyQuest Technology as cited by CNA. India expects its commercial space industry to be worth $44 billion within the decade and is encouraging private companies to invest in the sector, CNA reported. Singh said the patented technology would allow GalaxEye to expand to global markets and provide satellite imaging capacities that are not affected by weather for defense, agriculture, insurance, disaster response and more, The Print reported.

In the company's statement, Singh framed the grant as domestic invention with export ambition, saying: "This is not just a patent for us. This is an invention — an invention that came out of India," Business Standard reported. In the fuller version of the statement carried by Business Standard, Singh said India has demonstrated that it can manufacture world-class technology, but what is changing is that India is beginning to invent technologies that the world has not seen before. He added that GalaxEye is building global-first technology in India rather than importing or adapting it, and that protection in the United States validates what Indian deep-tech companies can create, according to the same Business Standard account.
