Beyond IT: Exploring India’s New Infrastructure for Autonomous Systems and AI

Abstract

The biennium of 2024–2025 stands as a definitive epoch in the scientific history of the Republic of India. Transcending its established reputation as a global hub for information technology services, the nation has decisively pivoted toward the creation of deep-tech intellectual property, sovereign hardware architectures, and advanced scientific infrastructure. This report offers a comprehensive, expert-level examination of this transformation across four critical pillars: complex orbital exploration, high-performance and quantum computing, autonomous robotic systems, and generative artificial intelligence. By synthesizing a vast array of technical data from agencies such as the Indian Space Research Organisation (ISRO) and the Defence Research and Development Organisation (DRDO), alongside the burgeoning private deep-tech sector, this document elucidates the engineering nuances, strategic imperatives, and future trajectories of India’s technological ecosystem. From the precise orbital rendezvous mechanics of the SPADEX mission to the tokenization efficiencies of indigenous Large Language Models (LLMs), the analysis reveals a concerted national strategy to achieve technological self-reliance ("Atmanirbhar Bharat") through high-risk, high-reward scientific endeavors.

1. The New Space Age: Mastery of Orbital Dynamics and Interplanetary Architectures

The trajectory of the Indian space program has shifted fundamentally from utility-driven missions—focused primarily on telecommunications and remote sensing—to audacious exploratory endeavors designed to master the complexities of extraterrestrial return, human spaceflight, and sustained orbital presence. This shift is underpinned by the maturation of critical technologies involving docking, re-entry, and modular mission architectures.

1.1 The Architecture of Return: The Chandrayaan-4 Paradigm

Following the historic soft landing of Chandrayaan-3 near the lunar south pole, the Indian Space Research Organisation (ISRO) has escalated its lunar ambitions with the Chandrayaan-4 mission. Officially approved by the Union Cabinet in September 2024 with a budgetary allocation of approximately ₹2,104.06 crore, this mission represents a quantum leap in operational complexity.¹ The mission objective has evolved from "presence" to "acquisition," specifically the collection and return of lunar regolith to Earth.

1.1.1 The Modular "Dual-Stack" Launch Strategy

Unlike its predecessors, which were launched as integrated stacks, Chandrayaan-4 necessitates a payload mass that exceeds the translunar injection capacity of a single LVM3 launch. Consequently, ISRO has adopted a novel "dual-stack" strategy involving two separate launches to assemble the spacecraft in Earth orbit before transit.³

The mission architecture comprises five distinct modules, divided into two functional stacks:

• Stack 1 (Descender & Ascender): This stack consists of the Descender Module (DM) and the Ascender Module (AM). Its primary function is to perform the lunar landing and subsequent lift-off. The Ascender Module essentially uses the Descender Module as a launchpad on the lunar surface, a technique that minimizes the mass required to return to orbit.³

• Stack 2 (Propulsion, Transfer, & Re-entry): This stack comprises the Propulsion Module (PM), Transfer Module (TM), and Re-entry Module (RM). This assembly is responsible for the orbital maneuvers, the return transit to Earth, and the final atmospheric entry.³

This distributed architecture allows for a significantly higher landed mass and redundant systems. The operational sequence requires these two stacks to perform a docking maneuver in an elliptical Earth orbit—a high-stakes ballet of orbital mechanics that validates the rendezvous technologies crucial for future sustained space stations.¹

1.1.2 Sub-Surface Sampling and Robotic Acquisition mechanisms

The scientific imperative of Chandrayaan-4 drives its engineering specifications. The lander is equipped with a sophisticated Surface Sampling Robot, a multi-degree-of-freedom robotic arm designed to scoop approximately 2 to 3 kilograms of regolith from the immediate vicinity of the landing site.³

However, surface samples are often chemically altered by solar wind and cosmic radiation. To access pristine geological material, the mission incorporates a deep drilling mechanism capable of extracting sub-surface samples. These samples contain a more accurate record of the Moon's thermal and geological history. A critical engineering challenge in this phase is "containerization." The samples must be transferred to a vacuum-sealed container within the Ascender Module. This sealing is vital to prevent contamination from the Earth's atmosphere upon return and to preserve volatile compounds, such as potential water ice traces, which would sublimate if exposed to vacuum or heat without protection.¹

The Ascender Module (AM) then performs a powered ascent from the lunar surface to dock with the Transfer Module (TM) in lunar orbit. Following the transfer of the sample container, the Transfer Module executes a Trans-Earth Injection (TEI) maneuver. The final phase involves the separation of the Re-entry Module (RM), which must survive the intense thermal loads of atmospheric entry to deliver the samples safely to Earth.³

1.2 Mastering the "Handshake" in Space: The SPADEX Mission

The capability to dock two spacecraft in orbit is a non-negotiable prerequisite for the Chandrayaan-4 mission architecture and the proposed Bharatiya Antariksh Station (BAS). The Space Docking Experiment (SPADEX) served as the critical technology demonstrator for these capabilities.

Launched on December 30, 2024, aboard the PSLV-C60, SPADEX was a dual-satellite mission consisting of a "Chaser" (SDX01) and a "Target" (SDX02).⁴ On January 16, 2025, India became the fourth nation in history to successfully execute an autonomous space docking operation, joining the United States, Russia, and China.⁶

1.2.1 Sensor Fusion and Autonomous Guidance

The docking process is an exercise in extreme precision, requiring the alignment of two objects moving at orbital velocities (approx. 7.8 km/s) with millimeter-level accuracy. The SPADEX mission utilized a suite of indigenous sensors, including laser rangefinders (LIDAR) for distance measurement and optical cameras for relative attitude determination.⁷

The mission profile involved a "hold-and-approach" strategy. The Chaser satellite maneuvered to a hold point at 15 meters relative to the Target, allowing ground control to verify systems. It then proceeded to a 3-meter hold point before executing the final capture.⁶ The onboard computers processed sensor data in real-time to adjust the thrusters, compensating for orbital drift and relative velocity differences.

1.2.2 Undocking and Re-Docking Validation

To fully validate the robustness of the system, ISRO executed a separation or "undocking" maneuver on March 13, 2025. The satellites were separated and allowed to drift into independent orbits.⁸ Subsequently, in April 2025, a second docking attempt was performed. This second maneuver was particularly significant as it was executed with full autonomy, bypassing the manual hold points used in the first attempt. This demonstrated the maturity of the autonomous Guidance, Navigation, and Control (GNC) algorithms required for future uncrewed supply missions to a space station.⁹

Furthermore, the mission demonstrated "power transfer" across the docked interface. One satellite successfully powered the heater element of the other through the docking ring.⁹ This capability is critical for modular space stations, where a central power generation module (with large solar arrays) may need to distribute electricity to docked laboratories or habitation modules that lack independent power generation.

1.3 The Human Dimension: Accelerating Gaganyaan

Parallel to robotic exploration, the Gaganyaan program—India’s human spaceflight initiative—has accelerated its testing schedule to ensure the safety of Indian astronauts ("Gaganyatris").

Table 1: Gaganyaan Mission Roadmap and Status (2024-2026)

Mission ID	Objective	Status / Timeline	Key Validation
TV-D1	Test Vehicle Abort Mission-1	Completed	Validated Crew Escape System (CES) at Mach 1.2
TV-D2	Test Vehicle Abort Mission-2	Scheduled Q3 2025	Validates CES under high dynamic pressure conditions 10
G1	Uncrewed Orbital Flight 1	Scheduled Q4 2025	Orbital module integrity; carries "Vyommitra" robot 10
G2 / G3	Subsequent Uncrewed Flights	Scheduled 2026	Full endurance testing of ECLSS (Life Support) 10
H1	First Crewed Mission	Scheduled ~2027	First Indian crew to Low Earth Orbit 11

1.3.1 Systems Qualification and Human Rating

The complexity of Gaganyaan lies in "human-rating" the launch vehicle and systems. The HLVM3 (Human Rated LVM3) has undergone extensive modifications to increase reliability. The Crew Escape System (CES), powered by rapid-burn solid motors, is designed to pull the crew module away from the rocket in the event of a catastrophic failure. The upcoming TV-D2 mission will test this system in a scenario simulating an abort during the period of maximum aerodynamic pressure (Max-Q), the most structurally challenging phase of flight.¹²

The G1 mission, carrying the humanoid robot "Vyommitra," will test the Environmental Control and Life Support System (ECLSS). Unlike biological astronauts, Vyommitra is equipped with sensors to measure parameters such as radiation, temperature, and pressure, providing a data-driven assessment of the cabin's habitability.¹³

1.4 The Private Sector Renaissance: "Space 2.0"

The years 2024-2025 marked the operational maturation of India’s private aerospace sector. Supported by the Indian National Space Promotion and Authorisation Centre (IN-SPACe) and liberalized Foreign Direct Investment (FDI) policies, startups have transitioned from R&D to commercial launch services.¹⁴

1.4.1 Skyroot Aerospace: Carbon Composites and Hybrid Propulsion

Hyderabad-based Skyroot Aerospace has advanced its Vikram series of rockets. Following the suborbital success of Vikram-S, the company targeted the orbital launch of Vikram-I in 2025.¹⁵

• Propulsion Architecture: Vikram-I utilizes a mix of solid and liquid propulsion. The lower three stages are powered by solid-fuel "Kalam" motors, known for their simplicity and high thrust. The upper stage, however, utilizes "Raman" engines, which burn hypergolic liquid propellants (MMH and N2O4). Liquid propulsion is essential for the upper stage as it allows for engine shut-off and restart, enabling the precise injection of satellites into specific orbits.¹⁶

• Manufacturing Innovation: The rocket features extensive use of carbon-composite structures, which are lighter and stronger than traditional aerospace aluminum. The Raman engines include significant 3D-printed components, reducing the part count and allowing for complex cooling channels that would be impossible to machine traditionally.¹⁸

1.4.2 Agnikul Cosmos: The Semi-Cryogenic Breakthrough

Agnikul Cosmos achieved a significant milestone with the "Agnibaan SOrTeD" mission in May 2024, launched from their private launchpad "Dhanush" at Sriharikota.¹⁹

• The Agnilet Engine: The core innovation is the "Agnilet," the world's first single-piece 3D-printed semi-cryogenic engine. It utilizes a propellant combination of Liquid Oxygen (LOX) and aviation-grade kerosene (Jet A-1). This "semi-cryogenic" mix offers a higher specific impulse (efficiency) than solid fuels without the extreme handling difficulties of liquid hydrogen.²⁰

• Additive Manufacturing: By printing the engine as a single component, Agnikul eliminated thousands of welds and fasteners. This not only reduces the points of failure but also allows for "launch on demand" capability, as a new engine can be printed in roughly 72 hours, decoupling the launch schedule from long manufacturing lead times.²¹

1.5 Solar Physics: The Vigil of Aditya-L1

While orbital and lunar missions grab headlines, India’s solar observatory, Aditya-L1, has been conducting critical science from Lagrange Point 1 (L1), 1.5 million kilometers from Earth. This unique vantage point allows for continuous observation of the Sun without occultation.²²

The mission's suite of seven payloads has provided new data on Coronal Mass Ejections (CMEs) and the "coronal heating problem"—the counter-intuitive phenomenon where the Sun's outer atmosphere is millions of degrees hotter than its surface. The Visible Emission Line Coronagraph (VELC) acts as an artificial eclipse, blocking the Sun's disk to image the faint corona, providing real-time space weather alerts that protect satellites and power grids on Earth.²²

2. The Silicon and Quantum Sovereignty: Computing at the Extremes

In the digital era, sovereignty is defined by the ability to process information. India’s strategy has evolved from software dominance to hardware independence, spanning indigenous supercomputing, RISC-V processor design, and the nascent field of quantum computing.

2.1 High-Performance Computing: The PARAM Rudra Ecosystem

In September 2024, Prime Minister Narendra Modi dedicated three new supercomputing facilities under the "PARAM Rudra" series.²³ These systems represent the apex of the National Supercomputing Mission (NSM), designed not just for raw speed but for specific scientific workflows.

2.1.1 Hybrid Architecture for AI and Simulation

The PARAM Rudra systems utilize a heterogeneous architecture. While traditional supercomputers relied heavily on Central Processing Units (CPUs), modern scientific workloads—such as molecular dynamics and weather modeling—benefit immensely from GPU acceleration.

• Computational Nodes: The systems are built on Intel Xeon Gold 6240R (Cascade Lake) processors for scalar tasks. However, significant compute power is derived from NVIDIA A100 GPU nodes.²⁴ For example, the system at the S.N. Bose Centre in Kolkata is optimized with high-bandwidth memory to handle the massive matrix multiplications required for material science simulations.²⁵

• Interconnect: The nodes are linked via InfiniBand HDR100. This high-speed interconnect acts as the system's nervous system, allowing thousands of cores to share data with microsecond latency. Without this, the system would merely be a cluster of independent servers rather than a unified supercomputer.²⁴

Table 2: PARAM Rudra Deployments and Scientific Focus

Location	Scientific Domain	Strategic Utility
GMRT, Pune	Radio Astronomy	Processing signals to detect Pulsars and Fast Radio Bursts (FRBs) 26
IUAC, New Delhi	Nuclear Physics	Ion beam simulation and atomic structure analysis 26
S.N. Bose Centre, Kolkata	Material Science	Quantum material simulation and cosmological modeling 26

2.2 The Quantum Leap: Indigenous Hardware Realization

The National Quantum Mission (NQM), with an outlay of ₹6,000 crore, has moved from policy to hardware. The mission aims to build intermediate-scale quantum computers (50-1000 qubits) by 2031.²⁷

2.2.1 The 6-Qubit Superconducting Processor

A landmark achievement in 2024 was the successful testing of a 6-qubit superconducting quantum processor by the Tata Institute of Fundamental Research (TIFR) in collaboration with DRDO and TCS.²⁸

• Physics of the Qubit: The processor uses superconducting circuits cooled to near-absolute zero. At these temperatures, the electrical resistance vanishes, and the circuit can behave as a quantum harmonic oscillator. Unlike a classical bit (0 or 1), these qubits can exist in a superposition of states.

• Strategic Significance: While 6 qubits is modest compared to global giants, the capability to design, fabricate, and control these qubits indigenously is the primary breakthrough. The team successfully executed quantum circuits via a cloud interface, validating the full technology stack—from the pulse control electronics to the dilution refrigerator interface.²⁸ This creates the "foundry" capability required to scale up to the planned 24-qubit and 100-qubit systems.³⁰

2.3 Silicon Independence: The Rise of RISC-V

India is aggressively pursuing semiconductor design independence through the RISC-V instruction set architecture (ISA). RISC-V is open-source, meaning Indian chip designers do not need to pay licensing fees to foreign entities like ARM or Intel.

2.3.1 Shakti and Vega Processors

Developed by IIT Madras and C-DAC respectively, the Shakti and Vega processor families have reached commercial maturity.

• The 7nm Roadmap: In October 2025, plans were unveiled for the first indigenous 7-nanometer Shakti processor, with a completion target of 2028. Moving to 7nm is critical because it allows for the transistor density required for modern smartphones and high-performance servers.³¹

• Space Qualification: The "IRIS" chip, a derivative of the Shakti architecture, was successfully booted in collaboration with ISRO. Designed for the harsh radiation environment of space, it features fault-tolerant memory structures to prevent "bit flips" caused by cosmic rays.³³ The successful deployment of open-source hardware in a critical domain like spaceflight validates the reliability of the indigenous architecture.

3. Automating the Future: Autonomous Agents in Physical Domains

Robotics in India has transcended industrial automation to enter unstructured and hazardous environments. Advancements in 2024-2025 were characterized by the integration of deep learning with hardware control, enabling autonomy in underwater defense, precision agriculture, and complex surgery.

3.1 Defense Robotics: The Silent Guardian of the Deep

In November 2025, the Naval Science & Technological Laboratory (NSTL) of DRDO unveiled the Man-Portable Autonomous Underwater Vehicle (MP-AUV).³⁴ This system addresses the acute threat of naval mines in littoral (shallow) waters.

3.1.1 Sensor Fusion and Edge AI

The MP-AUV is not a remotely operated vehicle (ROV) tethered to a ship; it is a fully autonomous robot.

• Acoustic Vision: Its primary sensor is a side-scan sonar, which emits acoustic pulses to create a high-resolution 3D map of the seabed.

• Onboard Intelligence: The AUV processes this sonar data in real-time using deep learning algorithms trained to recognize "Mine-Like Objects" (MLOs). By processing data on the "edge" (on the robot itself), the vehicle avoids the need to transmit massive raw data files through the difficult underwater medium.³⁵

• Swarm Logic: The system supports underwater acoustic communication, enabling a "swarm" capability. Multiple AUVs can coordinate their search patterns; if one detects a potential threat, it can alert others to converge or relay the data to a mother ship, significantly reducing the time required to clear a shipping channel.³⁵

3.2 Medical Robotics: Democratizing Precision Surgery

The surgical robotics market, long dominated by the da Vinci system, faces a credible challenger in the indigenous "SSI Mantra," developed by SS Innovations. By 2025, the system had achieved over 100 installations and performed thousands of procedures.³⁷

3.2.1 Frugal Engineering Meets High Tech

The SSI Mantra is engineered specifically to address the cost and infrastructure constraints of the developing world without compromising capability.

• Ergonomics: It features an open-faced console with a large 4K 3D monitor. This design allows the surgeon to remain aware of the operating room environment, unlike the immersive "hooded" consoles of competitors which can be isolating.³⁸

• Flexibility: The system uses independent robotic arm carts rather than a single massive boom. This modularity allows for flexible positioning in smaller operating rooms and enables the arms to approach the patient from optimal angles, reducing the risk of collision.³⁹

• Cost Efficiency: By significantly lowering the acquisition and recurring consumable costs, the system makes robotic cardiac and general surgery viable for Tier-2 and Tier-3 city hospitals, democratizing access to minimally invasive care.⁴⁰

3.3 Agricultural Robotics: The AI Weeder

In the agricultural sector, Niqo Robotics launched a spot-spray robot in 2025 that addresses the dual challenges of labor shortage and chemical overuse.⁴¹

3.3.1 Computer Vision at Speed

The core innovation is the "Niqo Sense" AI camera system.

• Green-on-Green Detection: Distinguishing a green weed from a green crop is a complex computer vision problem. Niqo’s deep learning models can identify weeds as small as 1 inch while the vehicle moves at 4.5 miles per hour.⁴¹

• Precision Actuation: Upon detection, high-speed nozzles target only the weed with a micro-dose of herbicide. This "spot spray" technology reduces chemical usage by up to 60%, drastically lowering input costs for farmers and reducing the environmental load of agrochemicals in the soil and water table.⁴³

4. The Intelligence Revolution: Sovereign AI Infrastructure and Models

While 2023 was the year of global AI discovery, 2024-2025 became the year India built its "Sovereign AI" stack. This strategy focuses on owning the compute infrastructure and developing "Indic" models that accurately represent the linguistic and cultural diversity of the subcontinent.

4.1 The Compute Backbone: The IndiaAI Mission

Recognizing that AI sovereignty is predicated on compute capacity, the Government of India launched the IndiaAI Mission with a budget exceeding ₹10,000 crore. The mission’s primary mandate was to secure a national stockpile of Graphics Processing Units (GPUs).⁴⁴

4.1.1 Strategic Procurement and Access

By mid-2025, the mission had successfully empanelled a compute capacity exceeding 38,000 GPUs, far surpassing the initial target of 10,000.⁴⁵

• Hardware Diversity: To avoid vendor lock-in, the procurement strategy involved a mix of accelerators, including NVIDIA H100/A100s, Intel Gaudi 2, and AMD MI300X chips.⁴⁷

• Viability Gap Funding: To stimulate the startup ecosystem, the government offered subsidies of up to 50% on the cost of this compute power. This lowers the immense barrier to entry for training large models, allowing Indian startups to compete with well-funded Silicon Valley entities.⁴⁸

4.2 The Rise of Indic LLMs

Indian developers have moved beyond simply fine-tuning Western models (like Llama or GPT) to training foundation models from scratch, optimizing them specifically for Indian languages.

4.2.1 Krutrim: India’s First AI Unicorn

Krutrim, launched by Ola’s AI division, released "Krutrim-2" in 2025, a 12-billion parameter model built on the Mistral-NeMo architecture.⁴⁹

• Data Sovereignty: Unlike Western models trained primarily on the English-dominated Common Crawl, Krutrim was trained on over 2 trillion tokens with a massive representation of Indic languages. This ensures the model captures cultural nuances and context often lost in translation by models like GPT-4.⁵⁰

• Performance: It claims to outperform significantly larger models on Indic language benchmarks, validating the thesis that high-quality, culturally specific training data is more valuable than raw parameter count.⁵¹

4.2.2 Sarvam-1: The Efficiency of Tokenization

Sarvam AI introduced "Sarvam-1," a 2-billion parameter model that highlights a critical technical innovation: custom tokenization.⁵²

• The Fertility Problem: "Tokenization" is the process of breaking text into numerical chunks for the AI to process. Standard Western tokenizers are inefficient for Indic scripts, often breaking a single Hindi word into 4-5 tokens (high fertility). This bloats the memory usage and cost of inference.

• The Solution: Sarvam developed a tokenizer optimized for Indian scripts, reducing the fertility rate significantly. This allows Sarvam-1 to process Hindi or Tamil text with the same efficiency as English, enabling high-performance AI to run on edge devices (like smartphones) rather than requiring massive cloud servers.⁵³

4.2.3 BharatGPT (Hanooman): Multimodality for the Masses

Developed by a consortium including IIT Bombay and Reliance Jio, "Hanooman" is a family of models ranging from 1.5B to 40B parameters.⁵⁵

• Voice-First Interaction: Hanooman is designed to be multimodal native, supporting text, voice, and video. In a country with varying literacy rates but high smartphone penetration, the ability to interact with AI via voice in 22 vernacular languages is a critical feature for inclusivity.

• Sectoral Focus: The model is being fine-tuned for specific high-impact domains like governance, healthcare, and education, aiming to function as a digital assistant for the grassroots population.⁵⁷

5. Conclusion: The Convergence of Capabilities

The scientific landscape of India in 2025 is defined by convergence. The boundaries between domains are blurring: space missions rely on indigenous processors; defense robotics utilize AI algorithms; and supercomputers simulate the quantum materials of the future.

Table 3: Summary of Strategic Breakthroughs (2024–2025)
