- To provide a backup system in case of failure of the Russian GLONASS system.
- To compete with the European Galileo system in the commercial sector.
- To offer more accurate navigation data than the US GPS system for civilian applications.
How did US restrictions on technology transfer from Russia affect India's space program?
How did US restrictions on technology transfer from Russia affect India's space program?
- They led to the cancellation of the GSLV program due to a lack of crucial components.
- They had no significant impact because India already had the necessary technology.
- They forced India to collaborate with European space agencies for technology development.
- They caused delays in the GSLV's development but ultimately spurred the indigenous development of cryogenic engine technology. (correct)

Study Notes
Early Years of ISRO: A Humble Beginning
- ISRO, the Indian Space Research Organisation, began as INSA (Indian National Space Research Committee) in 1962.
- India faced challenges like poverty, illiteracy, and post-war recovery during this time.
- Dr. Vikram Sarabhai, the father of the Indian space program, envisioned space technology for national development.
- Dr. Homi J. Bhabha, architect of India's nuclear program, supported Sarabhai's vision.
- The first sounding rocket launched on November 21, 1963, from a makeshift pad near a Kerala church.
- Sounding rockets tested space technologies and equipment.
Establishment of ISRO and Early Successes
- INSA became ISRO on August 15, 1969, under the Department of Atomic Energy.
- A separate Department of Space established in 1972, giving ISRO its own governing body.
- Aryabhata, India's first satellite, launched in 1975, using a Soviet rocket.
The SLV Project: A Path to Self-Reliance
- ISRO aimed for self-reliance in satellite launches, developing the SLV (Satellite Launch Vehicle).
- The first SLV launch (1979) failed due to a malfunction.
- ISRO persevered, successfully launching Rohini in 1980, establishing India's launch capabilities.
The Rise of PSLV: A Game-Changer
- ISRO developed the PSLV (Polar Satellite Launch Vehicle) for heavier payloads and higher orbits (polar and geosynchronous transfer).
- PSLV's first launch (1993) failed, but later launches achieved high success rates.
- PSLV launched many satellites, including Chandrayaan-1 and Mangalyaan.
- PSLV's reliability is noteworthy, launching multiple satellites successfully.
Mastering Cryogenics: The GSLV and the Quest for Independence
- ISRO faced the challenge of developing its own cryogenic engine technology for the GSLV (Geosynchronous Satellite Launch Vehicle) for heavier satellites in geosynchronous orbit.
- US restrictions on technology transfer from Russia slowed GSLV development.
- ISRO successfully developed indigenous cryogenic engine technology.
- The indigenous GSLV engine significantly enhanced India's launch capabilities.
The Birth of NavIC: A Strategic Necessity
- India's reliance on US GPS during the Kargil War highlighted the need for an indigenous navigation system.
- ISRO developed NavIC (Navigation with Indian Constellation), granting India space-based navigation sovereignty.
A Legacy of Success: Chandrayaan, Mangalyaan, and Beyond
- Chandrayaan-1 (2008) discovered water on the moon.
- Mangalyaan (2013) was India's first successful Mars mission, efficient and cost-effective.
- Chandrayaan-2 (2019) deployed a lander to the moon's surface.
- Chandrayaan-3 achieved a successful lunar landing near the Moon's south pole.
ISRO's Impact and the Future
- ISRO's spin-off technologies impact healthcare, agriculture, and disaster management.
- ISRO inspires a generation of scientists and engineers.
- Future plans involve a space station and international collaborations.
- ISRO's resilience and innovation demonstrate India's space exploration and technology achievements, contributing globally.
