    • Total funding reached $871 million across 241 funding rounds (July 2026).
    • Annual funding increased from $43 million (2021) to $200 million (2025).

    What is IN-SPACe?

    • Indian National Space Promotion and Authorisation Centre (IN-SPACe).
    • Established in 2020 under the Department of Space.
    • Acts as the single-window agency for authorising and promoting private participation in the space sector.
    • Facilitates private access to ISRO’s testing and launch facilities.

    Significance

    • Strengthens India’s commercial space industry.
    • Reduces dependence on government-led launch services.
    • Encourages innovation, investment, and private participation.
    • Enhances India’s competitiveness in the global launch market.

    Challenges

    • High capital requirement for launch vehicle development.
    • Need for a regular commercial launch cadence.
    • Dependence on imported critical components.

  • ISRO’s NavIC System Can No Longer Provide Standalone Navigation Services

    Why in the News?

    For the first time, the Government has admitted in Parliament that India’s NavIC (Navigation with Indian Constellation) cannot currently provide standalone positioning services, as only 3 operational satellites are available for navigation, while at least 4 satellites are required.

    What is the issue?

    • IRNSS-1F, launched in March 2016, completed its mission life and its onboard atomic clock failed, reducing the operational navigation satellites.
    • At present, only IRNSS-1B, IRNSS-1I, and NVS-01 are providing Positioning, Navigation and Timing (PNT) services.
    • As a result, NavIC cannot independently provide positioning services, though its timing service remains functional.

    What is NavIC?

    • NavIC (Navigation with Indian Constellation) is India’s regional satellite navigation system, developed by ISRO under the Indian Regional Navigation Satellite System (IRNSS).
    • It provides Positioning, Navigation and Timing (PNT) services over:
      • India, and
      • up to 1,500 km beyond its borders.
    • The original constellation was designed with 7 satellites.

    Why are four satellites necessary?

    • A navigation receiver determines its position through trilateration.
    • At least 4 satellites are required to accurately calculate Latitude, Longitude, Altitude, and Time correction
    • Without four operational satellites, standalone navigation becomes unreliable.

    Does this affect users?

    • No major impact on most users.
    • Smartphones, aircraft, ships and vehicles use multi-constellation GNSS receivers, combining signals from GPS (USA), Galileo (European Union), GLONASS (Russia), BeiDou (China), and NavIC (India)
    • Hence, navigation services continue without significant disruption.

    Current status

    • Standalone positioning: Not available.
    • Timing service: Functional.
    • Emergency message broadcasting: Functional.
    • Armed Forces: Continue using NavIC as part of a multi-constellation GNSS framework.

    Future roadmap

    • NVS-03 is ready for launch.
    • NVS-04 and NVS-05 are in advanced stages of development.
    • These satellites are expected to restore NavIC’s independent navigation capability.

    Significance of NavIC

    • Enhances strategic autonomy by reducing dependence on foreign navigation systems.
    • Supports: Defence operations, Disaster management, Maritime navigation, Aviation, Railways, Road transport, Precision agriculture, and Surveying and mapping
    • Provides secure and reliable navigation during emergencies or geopolitical conflicts.

    [A] Australia

    [B] Canada

    [C] Israel

  • What do you understand by ‘Standard Positioning Systems’ and ‘Protection Positioning Systems’ in the GPS era? Discuss the advantages India perceives from its ambitious IRNSS programme employing just seven satellites.

  • Discuss India’s achievements in the field of Space Science and Technology. How the application of this technology has helped India in its socio-economic development?

  • India has achieved remarkable successes in unmanned space missions including the Chandrayaan and Mars Orbitter Mission, but has not ventured into manned space mission, both in terms of technology and logistics? Explain critically.

  • What is India’s plan to have its own space station and how will it benefit our space programme?

    A space station is a habitable, long-term orbital laboratory for scientific research. India’s plan to build the Bharatiya Antariksha Station (BAS) represents a pivotal shift from short-duration missions to a sustained human presence in space.

    India’s Plan for Bharatiya Antariksha Station (BAS)

    The BAS is envisioned as a modular space station positioned in Low Earth Orbit (LEO) at an altitude of approximately 400-450 km.

    Modular Architecture: The station will consist of five modules launched in phases. The station’s total weight is estimated at 52 tonnes upon completion.

    Timeline:

    2028: Target for the launch of the first module, BAS-01 (Base Module).

    2028-2035: Sequential launch and docking of the remaining four modules.

    2035: Targeted year for the station to become fully operational.

    Technical Specifications: It is designed to accommodate a nominal crew of 3 to 4 astronauts for durations of 3 to 6 months, with a maximum capacity of 6 during crew handovers.

    The plan involves mastering Rendezvous and Docking (SpaDeX), advanced Environmental Control and Life Support Systems (ECLSS), and robotic arm operations.

    Benefits to India’s Space Programme

    Scientific

    Microgravity Research Platform: It provides a permanent laboratory for long-term experiments in biotechnology, materials science, and pharmaceuticals that cannot be replicated on Earth.

    Advanced Life Support Systems (ECLSS): Mastering the recycling of air and water is essential for sustaining life; BAS serves as the ultimate testbed for these “closed-loop” technologies.

    Technological

    Rendezvous and Docking Maturity: Successful operation requires perfecting the SpaDeX (Space Docking Experiment) technology, a critical skill for any future lunar or interplanetary assembly.

    Gateway to the Moon (2040): The station acts as a training ground for the Bharatiya Antariksha Yatri, preparing them for the planned 2040 Lunar Landing.

    In-Orbit Refueling and Servicing: BAS will pioneer technologies to refuel satellites in orbit, potentially extending the life of multi-billion dollar assets and reducing space debris.

    International

    Strategic Autonomy: Having an independent station ensures India is not dependent on foreign platforms for sensitive research or strategic orbital maneuvers.

    Geopolitical Leadership: It cements India’s role as a leader in the Global South, offering a potential platform for collaborative missions with nations lacking independent space access.

    Economic

    8. Income for ISRO by leasing out experiments, taking astronauts of other countries.

    9. Boosting space industry in India.

    10. Promotion of space tourism in India.

    The Bharatiya Antariksha Station is the cornerstone of India’s “Space Vision 2047.”
