The challenge
Without stationkeeping thrusters, many LEO communication satellites would re-enter the atmosphere and burn up in less than 3 months. The mass of a modern LEO communication satellite is so low (often under 500 kg) that the propulsion system needs to be under 25 kg. Yet the delta-V requirements for these same satellites can be 500 m/s or more over the mission lifetime.
Our solution
Our thruster system includes all components (thruster, PPU, propellant tank, feed, and propellant) in a very compact volume while providing the complete delta-V required for a 5+ year mission to a modern satellite. We call this the Apollo Constellation Engine (ACE).
Better performance, a fraction of the size
Apollo systems are dramatically smaller than alternatives with best-in-class performance for impulse per mass and impulse per volume.
Full deployment with fewer flights
Reducing satellite volume by up to 20% means more satellites per launch, enabling full deployment with up to 20% fewer launches.
Faster deployment accelerates revenue
With fewer flights, deploying a constellation far faster than projected can realize billions in revenue years ahead of schedule.
Shrinking one system shrinks others
Shrinking the propulsion system creates additional mass and cost savings for many other systems, reducing the overall budget.
Maximum reliability increases margins
Higher performance means more delta-V per burn and less frequent operation. This translates to higher reliability and lower OPEX.
Propellant with a proven flight history
Our compact zero-pressure tank and feed system has the highest ionization efficiency in the market.
