Indian Space Industry : Updates & Discussions


1. Skyroot is targeting another launch this year. Rocket no 2, 3 & 4 are under construction.
2. Cadence of 1 launch per month by end of 2027.
3. Skyroot wants to build re-usable rockets. Vikram 1 & 2 will continue as small satellite launch vehicles. Vikram 3 might not happen.
4. Vikram 1 will be the workhorse. Vikram 2 will carry 3X the payload of Vikram 1.
5. The re-usable rocket might be a medium or heavy lifter. Built to launch constellations of satellites. They will target USD 500 per kg with this re-usable launcher.
 

Isro is set to return to the launch pad for the first time since the PSLV-C62 failure on Jan 12, after receiving govt clearance to launch two strategically important satellites that had been sitting at the Sriharikota spaceport for several weeks.

As of Thursday (Aug 27), multiple sources confirmed to TOI that Isro was gearing up to launch Gisat-1A, also designated EOS-05, in the early hours of Sept 4.

TOI had highlighted on Aug 3 that Gisat-1A and navigation satellite NVS-03 were ready for launch but were awaiting govt approval. Gisat-1A is designed to provide near real-time images of large “areas of region of interest” at frequent intervals, similar to the original Gisat-1 mission.

“This is more than a replacement satellite. It has several improvements over Gisat-1,” a senior scientist said. While primarily a civilian satellite, its ability to provide frequent observation could also aid the country’s armed forces in planning operations.

The 2.2-tonne class satellite is expected to strengthen India’s Earth observation capabilities by providing observation of the subcontinent under cloud-free conditions.

It will provide spectral signatures useful for agriculture, forestry, mineralogy, disaster warning, cloud properties, snow, glaciers and oceanography.

Gisat-1A is expected to restore India’s capability for frequent geostationary observation of the subcontinent. NVS-03, the other satellite that had been awaiting clearance, is also expected to be launched after Isro resumes its launch campaign.

Indian space technology startup GalaxEye said on Tuesday it had secured a U.S. patent for a system that synchronises optical and radar sensors on satellites, ‌strengthening its position in the fast-growing market for Earth imaging data.

The patent award comes at a time when demand for satellite-based intelligence is growing across security, agriculture, insurance and disaster-response applications.

GalaxEye, which has so far raised around $21 million in funding, said the patent covers technology that synchronises optical and radar sensors to capture precisely aligned images of the same location simultaneously, delivering reliable Earth observation data even in cloud cover ‌and ⁠darkness.

"This patented technology enables us to serve the global markets and provide weather-agnostic imaging capabilities across sectors," CEO Suyash Singh said.

The startup, founded by IIT Madras engineers, plans to build a 30-satellite ⁠constellation over the next five years, backed by a growing commercial pipeline across domestic and international customers, it said.

In August, GalaxEye acquired Bengaluru-based ⁠spacecraft engineering firm StarOps to strengthen its in-house manufacturing and satellite system capabilities.​
 
Temasek, London-Listed Seraphim LeadSpacetech Startup Pixxel's Series C

Bengaluru-headquartered space technology startup Pixxel said on Monday it has raised $100 million (around Rs 944 crore) in a Series C funding round co-led by Singapore state investment firm Temasek and the London-listed Seraphim Space Investment Trust Plc.

The round included new investors 360 One Asset and IMM Investment, alongside existing backers Radical Ventures and growX Ventures and other unnamed investors, the company said in a statement on its website. Pixxel counts Alphabet Inc.'s Google among its earlier investors, who was roped in for its 2023 Series B round.

The round takes Pixxel's total funding since it was founded in 2019 to $195 million. It is also the largest single funding round raised by an Indian space-tech company to date.

Pixxel raised $25 million in Series A led by Radical Ventures in 2022, $36 million in Series B in 2023 that brought in Google, and $24 million in a Series B extension round in December 2024.

Pixxel was founded by Awais Ahmed and Kshitij Khandelwal, who started the company as undergraduates with what they describe as the ambition of building "a health monitor for the planet."

The company's hyperspectral imaging satellites split reflected light into narrow wavelength bands, a technique that can reveal details about the Earth's surface — crop stress, mineral composition, gas leaks — that conventional optical imagery cannot capture.

It has since built Aurora, a software platform that converts satellite data into easy-to-use information, and has expanded to serve commercial and sovereign missions.

Pixxel described the new financing as directed toward four areas: extending its next-generation Honeybee satellite constellation from hyperspectral into short-wave infrared (SWIR) sensing; growing Aurora's abilities; deepening its work building spacecraft and mission infrastructure for government-run space programmes; and scaling satellite manufacturing capacity for its own constellations as well as commercial and government orders.

The company said it has placed six Firefly satellites in orbit to date and has supported commercial, civil and intelligence missions globally since launching Aurora.

The round comes as India's private space sector, opened to non government players following 2020 policy reforms and the creation of sector regulator IN-SPACe, has drawn a cluster of venture-backed entrants including launch-vehicle makers Skyroot Aerospace and Agnikul Cosmos and satellite maker Dhruva Space.
