From 200 km to geostationary.
Four altitudes, four machines. Each one solves a different problem of getting a satellite where it needs to be, and keeping it there.
We move satellites.
Electric and green propulsion, transfer vehicles and complete spacecraft. Flight-proven in orbit, built in Bengaluru.
Ultra-low Earth orbit
Project 200
A satellite built to fly where the atmosphere still drags. Lower means sharper imaging and shorter signal paths.
- Altitude
- 180-250 km
- Propulsion
- Arka Air
- Next flight
- 2028 or later
In development. Unveiled September 2024.
Low Earth orbit
Pushpak पुष्पक
Named for the flying chariot of the epics.
A transfer vehicle that carries small satellites from the rocket's drop-off point to the exact orbit each one needs.
- Payload
- up to 750 kg
- Delta-V
- up to 7 km/s
- Propulsion
- Electric + green
Agreement with NSIL, ISRO's commercial arm, to fly on its launches.
Manoeuvring in orbit
Rudra रुद्र
The roarer, the Vedic god of storms.
Green monopropellant thrusters for the hard, fast burns: orbit changes, collision avoidance, deorbit. Safer to handle than hydrazine.
- Thrust
- 1 N to 100 N
- Specific impulse
- 235-255 s
- Propellant
- Green
Flown on PSLV-C58 (January 2024) and PSLV-C60 (January 2025).
Raising to geostationary
Arka अर्क
A ray of the sun.
Hall-effect electric thrusters that push gently for months, spiralling a satellite outward on a fraction of the propellant.
- Power
- 50 W to 5 kW
- Thrust
- 3-260 mN
- Specific impulse
- up to 2,000 s
Flown on PSLV-C55 (April 2023) and PSLV-C58 (January 2024).
Three flights on ISRO's PSLV. A complete satellite in orbit since March 2026. Propulsion delivered in under six months.

Hall-effect electric thruster
Arka
Long, efficient burns for orbit raising and station keeping.
