Aerospace Flight Heritage – ACS / Apogee Bipropellant Thrusters
The MON / Hydrazine LEROS™ 1, 1b and 1c engines have provided reliable,
high-performance apogee propulsion for a large number of geostationary
satellites. Additionally, LEROS™ engines have been used on interplanetary
exploration/research missions including the spectacular Near Earth
Asteroid Rendezvous (NEAR) mission [LEROS™ 1], Mars Global Surveyor
[LEROS™ 1b] and Mars ODYSSEY [LEROS™ 1b]. A LEROS™ 1b is currently making the course correction maneuvers for the Mercury MESSENGER mission. In
all cases, LEROS™ engine performance has been flawless. The LEROS™ 2b adds MMH capability to the apogee engine family, and has successfully demonstrated flight performance.

Propellant Manufacturing and Ground Support Equipment
AMPAC-ISP’s Westcott facility can supply a variety of propellants, including,
but not limited to, hydrazine and hydrazine-based products. We also have
expertise in compatibility studies and the handling of a wide range of other
propellants (e.g. based on red fuming nitric acid and mixed amine fuels).
We also offer wide-ranging expertise and experience in aerospace
ground support.
