About
The Station Keeping Thruster Unit is designed for spacecraft station keeping operations. It was released in 1999 and boasts a guaranteed service life of 7 years. The unit is flight qualified and can be adapted to meet specific customer requirements. It consists of two thermocatalytic thrusters: one main and one redundant, both using hydrazine as propellant. The thermal management of the unit is ensured by four heaters (two main and two redundant), a radiator, and a set of Multi-Layer Insulation (MLI). Unit temperature is continuously monitored by four integrated temperature sensors. The estimated production and delivery time is 12 months, not including the time required for material procurement (4 months) and procured parts and components (6 months).
