1 n HPGP Thruster - ECAPS - SmallSat Catalog - Orbital Transports

1 N HPGP Thruster

The 1 N HPGP thruster enables high thrust apogee, reaction control and proximity operations maneuvering for satellites.

The thruster operates on LMP-103S low-toxicity monopropellant with 1.3X the density-Isp of hydrazine. Additionally, LMP-103S offers up to 72%(1) cheaper spacecraft loading as compared to hydrazine, reducing the total life-cycle cost of the mission.

The Propellant is long term storable (>15 years) and enables "fuel at the factory" for rapid response satellites. Over 25 satellites are presently flying the 1 N HPGP thruster (+100 units in space, and +160 additional delivd to customers).
