OneArc Space Technologies is laying the computational and engineering foundations for reusable launch vehicle technology — making space access sustainable, affordable, and proudly Indian.
OneArc Space Technologies is an Indian space startup focused on developing the core technologies required for India's first fully reusable launch vehicle. We are building the computational models, control systems, control surfaces, and propulsion architectures that will make reusable rocketry a reality for India.
Operating as a division of Engatetal Solutions (OPC) Pvt. Limited, headquartered in New Delhi, we combine deep aerospace engineering expertise with cutting-edge computational techniques to solve the hardest problems in rocket reusability.
Building the full spectrum of technologies needed for rocket reusability — from computational fluid dynamics to autonomous landing systems.
Advanced CFD simulations, trajectory optimization algorithms, and thermal analysis models for accurate prediction of vehicle behavior through all flight phases.
GNC (Guidance, Navigation, and Control) systems for precise trajectory tracking, powered descent, and autonomous landing capabilities for booster recovery.
Grid fins, aerodynamic surfaces, and thrust vector control mechanisms engineered for supersonic and hypersonic regimes during powered return flights.
Engine performance modeling, relight simulation for boostback and landing burns, and propellant management system design for multi-burn mission profiles.
Optimal ascent profiles, boostback trajectory planning, and landing precision algorithms to maximize payload capacity while ensuring safe booster return.
Lightweight structural design, thermal protection systems, and landing leg mechanisms engineered to withstand repeated launch and landing cycles.
Four foundational pillars guiding our research and development towards achieving rocket reusability for India.
Developing high-fidelity computational models and simulation frameworks that accurately predict aerodynamic, thermal, and structural behavior of reusable launch vehicles across all flight regimes — from launch to hypersonic re-entry to powered landing.
Building intelligent GNC systems capable of real-time decision making for autonomous booster recovery, including powered descent guidance, precision landing algorithms, and fault-tolerant control architectures that ensure mission safety.
Designing vehicle systems for repeated use — from reusable thermal protection systems and rapid-turnaround engine designs to landing leg mechanisms and vehicle inspection automation — reducing per-launch costs by an order of magnitude.
Committed to building 100% indigenous capabilities in reusable rocketry, reducing dependence on foreign technology, contributing to India's self-reliance in space access, and fostering a homegrown aerospace ecosystem of world-class caliber.
A phased approach to developing, testing, and deploying India's first reusable rocket technology.
Establishing core computational models, CFD frameworks, and simulation pipelines. Building the foundational aerodynamic and structural analysis tools required for reusable vehicle design. Assembling the founding engineering team.
Developing GNC algorithms, control surface prototypes, and TVC systems. Conducting hardware-in-the-loop simulations and subsystem-level testing. Validating computational models against experimental data.
Sub-scale flight demonstrators, powered landing tests, and integrated vehicle simulations. Progressive testing from ground tests to hop tests to full flight profile demonstrations of controlled descent and landing.
Full-scale reusable first stage development, orbital flight testing, booster recovery demonstration, and iterative vehicle improvements toward operational reusable launch service for India and the global market.
