About
The Cold Ammonia Corrective Propulsion System (CPS) is designed for correction and stabilization of orbit parameters and for zeroing the kinetic moment of flywheel engines in the spacecraft orientation system. It uses cold ammonia as the working body, with components including a working-fluid tank with a film electric heater, a receiver, a steam generator, and a valve with an integrated micro nozzle. Flight heritage includes components flown on the “Meteor” and “Electro” spacecraft. First released in 2014 with a 5-year guaranteed service life, 12-month delivery time. Adaptable to customer requirements.
