India · Global Propulsion Systems

Independent by design.
Engineered for orbit.

Epoch Orbits develops next-generation aerospike propulsion and orbital mobility systems from India — independent, export-ready, and built for Indian missions and space operators worldwide.

The Problem

Space missions still run on
propulsion they cannot control.

Export dependency

Foreign controls and government veto rights can block access to critical propulsion hardware when a mission is ready to fly.

2+ year lead times

Global OEM procurement cycles stall constellation launches and leave capital waiting in standby configurations.

Monopoly pricing

Established primes inflate integration costs when Indian and international operators have no independent propulsion alternative.

Zero customisation

Rigid foreign platforms force satellite buses to conform to pre-existing designs, limiting mission-specific payload optimisation.

Our Technology

Two projects. One propulsion roadmap.

From an India-built demonstrator to orbital operations — a phased path to propulsion independence for Indian and international missions.

Regional Anchors

From India to every orbit.

India is our engineering and intellectual-property base. We are building a distributed network of launch, test, satellite, and institutional partners so the same propulsion platform can serve missions at home and around the world.
