    • Low Earth Orbit (LEO): Satellites in LEO offer the advantage of high-resolution imaging and frequent revisit times, crucial for dynamic surveillance and rapid data acquisition.

    • Geostationary Orbit (GEO): GEO satellites provide continuous, wide-area coverage, making them ideal for persistent monitoring of specific regions and serving as critical communication relays.

  • Enhanced Surveillance Capabilities: A primary objective of this phase is to achieve significantly shorter revisit times and deliver higher-resolution imaging. This enhanced capability is tailored explicitly for comprehensive surveillance over critical regions, including China, Pakistan, and the strategically vital Indian Ocean Region, providing India with an unprecedented advantage in situational awareness.

Recognising the urgency of this initiative, concerted efforts are already underway to compress timelines and accelerate the launch cadence, ensuring that these vital assets achieve orbital deployment as swiftly as possible. This aggressive schedule underscores the strategic importance and high priority assigned to the SBS programme, instilling a sense of the immediate need for these advancements in the audience.


Crafting a Comprehensive Military Space Doctrine: Defining the Rules of Engagement

Parallel to the rapid development and deployment of the satellite constellation, India’s Defence Space Agency, operating under the aegis of the Integrated Defence Staff, is diligently working to finalise a comprehensive Military Space Doctrine. This foundational document, spearheaded by the visionary leadership of Chief of Defence Staff General Anil Chauhan, provides the overarching framework for India's military operations in the space domain. Key tenets of this doctrine will include:

  • Rules of Engagement in Space: The doctrine will meticulously establish clear and precise rules of engagement for military activities in space, addressing issues such as space situational awareness, debris mitigation, and responses to adversarial actions. This is crucial for maintaining stability and deterring aggression in the increasingly contested space domain.

  • Joint Operations Across Domains: A core principle of the doctrine will be the seamless integration of space assets into joint operations across all traditional domains: land, sea, and air. This ensures that space capabilities are not standalone but are fully synchronised to enhance the effectiveness of conventional forces, providing a force multiplier across the spectrum of conflict.

  • Cultivating a "Space Culture": Beyond operational guidelines, the doctrine aims to foster a holistic "space culture" within the Indian armed forces and the broader strategic community. This encompasses promoting dedicated research into advanced space technologies, developing sophisticated space strategies, and implementing specialised training programmes for personnel operating in and leveraging the space domain. This long-term investment in human capital and intellectual development is vital for sustaining India's space advantage.

The finalisation and release of this doctrine are slated to occur within the next two to three months, a testament to the urgency and priority attached to defining India's strategic posture in space. Its promulgation will unequivocally cement space's status as the "ultimate high ground" in modern warfare, a domain where mastery can dictate the outcome of future conflicts.

Leveraging India’s Space Research Prowess: A Foundation of Excellence
