Electric Propulsion

To overcome hurdles associated with our own pursuits relating to precision formation-flight, we have had to build and qualify our own electric propulsion system from scratch. This has also allowed us to compress the price-point associated with our ORB family of satellite platforms to compelling levels. And has enabled us to build the Guardian family of satellites in a more cost-effective way.

The Nova product-line is the baseline propulsion system used in the ORB-class satellite platforms. It is specifically built to capitalise on usage of the often-neglected “tuna-can” volume made available for nanosatellites, minimising impact on volume consumed within the platform. The Kilonova and Supernova product-lines, built for compatibility with CubeSat platforms, are upgradable variants of propulsion for larger ORB-class and Guardian-class satellite platforms.

Typical Functions:

Accelerated deployment of constellations​

Accelerated RAAN drifting​

Formation maintenance​

Orbit raising

Station-keeping/Life-extension​

Collision avoidance​

Active deorbiting at end of mission

System Features:

Compact, efficient Carbon Nanotube (CNT) neutralizers​

No pressurized tanks or moving parts​

Low melting point, liquid metal propellant​

Integrated electronics​

Redundant design features​

These flight-qualified product-lines will be available for shipping from May-21 onwards.
