Take a take a look at the important ideas, phrases, quotes, or phenomena daily and brush up your information. Here’s your information nugget on GalaxEye’s Drishti satellite for in the present day.
First-of-its-kind satellite named Drishti by Indian start-up, GalaxEye, was launched on 3 May, 2026 by Falcon 9 rocket of SpaceX from the Vandenberg Space Force Base in California, United States, as one of the 45 payloads on the CAS500-2 mission.
Let’s be taught what makes this satellite distinctive.
1. Imaging satellites are typically geared up to take multi-spectral or hyper-spectral (optical) pictures, or they use Synthetic Aperture Radar (SAR). Both of these sorts of satellite knowledge are used extensively.
2. However, each of these imaging programs have their very own limitations. Multi-spectral pictures are clear and simple to grasp, however they don’t seem to be efficient throughout cloudy climate or evening time, as an example. SAR indicators can penetrate clouds and take steady pictures, however they don’t seem to be intuitive. Like X-ray pictures, they want specialists to glean the knowledge.

3. SAR and optical sensors are designed in several methods. They take a look at the Earth at totally different angles (parallax). So, if they’re positioned facet by facet, for instance, the optical sensor could be Bengaluru whereas SAR is capturing Dubai at that instantaneous. There is subject of seize time (temporal gaps) as effectively which create issues in mission-critical purposes.
4. To remedy this subject and get clear and intuitive pictures from area, Indian start-up, GalaxEye, designed the Drishti satellite the place each imaging sensors are placed on the satellite and function in sync with one another to provide simultaneous imaging of the identical place. This eliminates the necessity for customers to manually align datasets from two totally different satellites.
5. Drishti satellite combines the readability of Optical Imaging with the all-weather reliability of SAR on a single platform to ship intuitive, dependable, all-weather Earth imagery that’s already analysis-ready. For this purpose, the corporate is describing its innovation as Opto-SAR expertise.
6. “The onboard and ground-based software uses AI models for sub-pixel co-registration and jitter correction. These algorithms ensure that every single data point from both sensors is captured and processed as part of a single, unified dataset”, as per the Company.
7. The purpose that that is first of its kind is as a result of it is a primarily tropical nation’s downside. Most of the satellite corporations have historically been primarily based within the western nations, and cater to the calls for of these nations. Weather is comparatively extra predictable, and the skies are comparatively cleaner and clearer there. They don’t have the identical kind of points with clouds that nations like India face.
India’s non-public area corporations and their innovations
1. Skyroot Aerospace: It is prone to develop into the first non-public firm to launch an orbital area rocket- Vikram-1. Vikram-1 is a multi-stage launch car with stable and liquid fuel-based engines designed for launching satellites weighing as much as 350kg to low earth orbit.
— What makes Vikram-1 different is that the rocket is made of carbon composite as an alternative of metals, and homes a 3D-printed, indigenously made engine — making its manufacturing and meeting simpler, faster, and cheaper.

— Skyroot was additionally the first non-public firm to hold out a single-stage sub-orbital flight in 2022, adopted by one other firm, Agnikul. A sub-orbital flight is launched at a slower velocity than the orbital velocity, so it reaches outer area however can’t get into an orbit round Earth.

2. Pixxel: Space-tech startup Pixxel on May 4, introduced a partnership with LLM supplier Sarvam AI to develop and construct India’s first orbital knowledge centre satellite known as The Pathfinder.
— Expected to achieve orbit by the top of 2026, the 200-kg satellite will home GPUs (graphics processing items) that can be used to hold out coaching and inference of Sarvam’s AI mannequin.
— Unlike typical satellite computing, which depends on low-power edge processors optimised for survival slightly than efficiency, the Pathfinder satellite will home the identical era of {hardware} as on-ground knowledge centres used to energy frontier AI fashions.

3. Agnikul Cosmos: In 2024, Indian area startup Agnikul Cosmos efficiently launched its first sub-orbital check car powered by the world’s first single-piece 3D-printed rocket engine. The engine—known as Agnilet—makes use of sub-cooled oxygen as gas.
— ‘Agnibaan – SOrTeD’ Sub-Orbital Technology Demonstrator additionally has the distinctive distinction of having been launched from India’s first non-public launch pad known as ‘Dhanush’ established by Agnikul. It can be India’s first semi-cryogenic engine-powered rocket launch.
BEYOND THE NUGGET: IN-SPACe
1. In 2020, the federal government created IN-SPACe (Indian National Space Promotion and Authorisation Centre) and formulated the Indian Space Policy 2023 with the intent to facilitate better participation of non-public trade within the area sector.
2. IN-SPACe is a single-window, unbiased, nodal company that features as an autonomous company within the Department of Space (DOS).

3. It is a facilitator and likewise a regulator. It acts as an interface between ISRO and personal events, and assesses how greatest to utilise India’s area sources and improve space-based actions.
4. “It is responsible to promote, enable, authorize and supervise various space activities of non-governmental entities including building launch vehicles and satellites and providing space-based services; sharing space infrastructure and premises under the control of DOS/ISRO; and establishing of new space infrastructure and facilities”, as per ISRO.
5. In 2025, a new draft of the Space Activities Bill was finalized to realize the purpose of a 44 billion greenback area market in India by the yr 2033, not less than one fourth of which, 11 billion {dollars}, is meant to be generated from exports. In 2022, India’s area market was estimated to be value 8.4 billion {dollars}.
