About
The Station Keeping Thruster Unit is engineered for spacecraft station keeping applications. It was released in 2009 and boasts a guaranteed service life of 10 years. The unit operates using hydrazine propellant and incorporates two modified thermocatalytic thrusters: one main and one redundant, ensuring operational reliability. Its thermal management system includes four heaters (two main and two redundant), a radiator, and a set of Multi-Layer Insulation (MLI) to maintain optimal operating temperatures. Four temperature sensors are integrated for continuous monitoring of the unit’s thermal state. While not flight qualified, the product offers the possibility of adaptation to specific customer requirements. The estimated production and delivery time is 12 months, not including the time required for material procurement (4 months) and parts and components procurement (6 months).
