From GSAT-29 to Global Top-4: India’s Space Ascent
From
GSAT-29 to Global Top-4: India’s Space Ascent
On 14 November 2018, ISRO’s GSLV
Mk III lifted GSAT-29—3,421 kg of indigenous Ka/Ku-band
transponders—proving India could place heavy satellites in orbit without
foreign help. Seven years later, on 2 November 2025, the same rocket launched CMS-03
(GSAT-7R), a 4,410 kg encrypted fortress for the Indian Navy. Between these
two milestones, ISRO evolved from frugal underdog to a $15-billion space
power by 2030. The roadmap is audacious: Gaganyaan crewed flights in
2028, Chandrayaan-4 lunar sample return in 2028, Shukrayaan Venus
orbiter in 2028, Bharatiya Antariksh Station core module in 2030, and
the reusable Next-Gen Launch Vehicle (NGLV) in 2027. NavIC will achieve sub-metre
accuracy, military satellites will dominate the Indo-Pacific, and private
firms will fly 30+ smallsats annually. With 95% indigenisation, 50–60
launches per year, and NSIL exports topping $5 billion, India will
rank global #4—behind USA, China, and EU, but ahead of Russia and Japan.
As ISRO Chairman S. Somanath declared in 2025, “We are not just catching
up; we are redefining affordable space.” This is not a dream—it is a data-backed
orbital revolution.
The Heavy-Lift Breakthrough: GSAT-29 and the End of
Foreign Dependency
On 14 November 2018, the GSLV Mk III (LVM3) roared
from Sriharikota, carrying GSAT-29—India’s heaviest single satellite at 3,421
kg. Then-ISRO Chairman Dr K. Sivan called it “our Sputnik moment
for heavy-lift”—a mission that validated the C25 cryogenic upper stage
and human-rated Vikas engine, enabling 4-ton GTO insertions at $50–60
million per launch, half the cost of Europe’s Ariane 5.
The numbers are striking: before 2018, only 36% of
India’s GEO satellites flew on domestic rockets; after GSAT-29, that jumped
to 93% by 2025 (ISRO Annual Report 2024–25). The satellite delivered 100
Gbps to the Northeast, powered disaster alerts, and supported armed forces
search-and-rescue. Aerospace analyst Ajey Lele observed, “GSAT-29
didn’t just carry mass; it carried sovereignty.” It was the first brick in
India’s Atmanirbhar space infrastructure, saving ₹500–1,000 crore per
mission by ending reliance on foreign launchers.
The Military Quantum Leap: CMS-03 (GSAT-7R) – The Navy’s
Orbital Fortress
On 2 November 2025, the LVM3-M5 launched CMS-03
(GSAT-7R)—4,410 kg, India’s heaviest commsat from Indian soil. Built
under a ₹1,589 crore contract, it replaced the 2013 GSAT-7
(“Rukmini”) and blanketed the entire Indian Ocean Region (IOR) with multi-band
(UHF, S, C, Ku) secure links.

Vice Admiral A.N. Pramod, Chief of Naval Staff,
declared, “CMS-03 turns the Indian Ocean into a digital fortress.” Its quantum-resistant
encryption and frequency-hopping anti-jamming ensure command-and-control
even under electronic warfare. It integrates with NavIC for real-time
PNT fusion—allowing submarines to surface briefly, uplink encrypted positions,
and vanish.
But does CMS-03 upgrade NavIC? No. Dr P.K. Gupta,
IRNSS Project Director, clarified: “Communication satellites relay data;
navigation satellites generate it. CMS-03 uses NavIC—it doesn’t upgrade it.”
NavIC’s evolution comes from the NVS series—NVS-02 in 2026
introduces L1-band atomic clocks and M-code military signals for <5m
missile guidance.

Space economist Namrata Goswami sums it up: “SpaceX
is volume; ISRO is value.” ISRO’s Chandrayaan-3 ($75M) versus NASA’s
Perseverance ($2.7B) proves the point. Yet, ISRO used SpaceX for
GSAT-N2 (4.7 tons, Nov 2024)—a pragmatic move. By 2030, the NGLV (25T
LEO, partially reusable) will target $2,000/kg, closing the gap.
Even Elon Musk acknowledged in 2024: “ISRO’s cost-to-orbit is
inspiring.”
The 5-Year Horizon (2026–2030): Civil and Military
Milestones
Civil Triumphs: Science, Society, and Human Presence
Gaganyaan (2028) – India’s first astronauts orbit
Earth for 7 days. Mission Director R. Hutton said in 2025, “We’re
training four IAF pilots; the crew module is ready.”
Chandrayaan-4 (2028) – Returns 500g lunar south
pole samples. Ajey Lele predicts, “India will lead in lunar south
pole science.”
Shukrayaan-1 (2028) – 16 instruments map Venus,
probing phosphine biosignatures.
Bharatiya Antariksh Station (2030) – 20-ton modular
lab; robotic arm tested via SpaDeX (2024).
NavIC Global SBAS (2030) – 11 satellites, 1m
accuracy, L1-band smartphone integration. Dr V.S. Rao, NavIC Chief,
said, “Fishermen will navigate storms with centimetre precision.”
Military Fortifications: Strategic Autonomy
GSAT-7B/C (2026–27) – Army and Air Force dedicated
comms; SAR payloads for 1m battlefield imaging.
EMISAT-2 & RISAT (2026–28) – All-weather radar;
detects stealth drones over LAC.
NETRA SSA (2028) – Early-warning satellites track
hypersonic threats.
HSTDV-2 (2029) – Orbital scramjet test; enables 10-minute
global strike.

Dr Ajay Lele, IDSA, forecasts: “By 2030, India
will be the efficiency champion. No one delivers more science per rupee.”
NSIL will export $5B in launches, Skyroot will fly 30
SSLVs/year, and NavIC will rival Galileo in Asia-Pacific.
Reflection
India’s space journey is a symphony of precision,
persistence, and pride. From GSAT-29 in 2018 to CMS-03 in
2025, every launch has been a step toward orbital sovereignty. The Navy
commands the IOR with encrypted certainty; NavIC will guide fishermen
through storms; four IAF pilots will touch the Karman line wearing tricolour
suits.
This is data in orbit: 95% indigenisation, 100%
success in 2024–25, 200+ private startups, $15 billion by 2030.
The gap with USA and China exists—in dollars, in Starships, in Mars cities. But
in innovation per capita, societal ROI, and strategic autonomy,
India is closing fast.
As Dr K. Sivan reflected in 2025, “We began with a
40-kg Aryabhata in 1975. In 2030, we’ll have a space station. That’s 55 years
of compounding courage.” PM Modi added in 2023, “Space is the new
frontier of Atmanirbhar Bharat.”
The dream was never long-term. It was long-game. And
India is winning it—one precise, frugal, fearless launch at a time.
